S-1 plus apatinib as first-line palliative treatment for stage IVB gastroesophageal junction adenocarcinoma: A case report and review of the literature.
Apatinib has been proven to significantly prolong the survival of the patients with advanced chemotherapy-refractory gastric cancer. To date, studies on apatinib plus S-1 as first-line palliative therapy for metastatic gastroesophageal junction (GEJ) cancer are rare.. A 61-year-old female patient was admitted with dysphagia, significant loss of body weight, and poor performance status.. Endoscopic biopsy revealed the diagnosis of poorly-differentiated GEJ adenocarcinoma, and the patient was clinically staged as T3NxM1G3 (IVB).. She had received 4 cycles of palliative therapy using oral apatinib (425 mg daily) plus S-1 (40 mg twice daily for 4 weeks, with a 2-week drug-free interval), followed by maintenance low-dose apatinib (250 mg daily) plus S-1 at the same dosage thereafter.. Her progression-free survival was nearly 5 months, and the overall survival was >11 months up to now. The adverse events were tolerable.. Apatinib plus S-1 might be an alternative option for late-stage GEJ cancer. However, high-quality trials are warranted before the recommendation of this therapeutic regimen.

S-1 plus apatinib followed by salvage esophagectomy for irinotecan-refractory small cell carcinoma of the esophagus: A case report and review of the literature.
Small cell carcinoma of the esophagus (SCCE) is an uncommon but lethal disease characterized by dismal prognosis. Only 10% of advanced SCCE patients survive longer than 1 year. Resection is a choice for limited-stage cases, whereas the optimal treatment regimen for primary SCCE is yet to be elucidated. To the best of our knowledge, the efficacy of S-1 plus apatinib for irinotecan-refractory SCCE has not been reported before.. A 61-year old, previously healthy male was admitted for dysphagia and fatigue. Endoscopic biopsy revealed a tumor in the middle third of the esophagus. Further exams including abdomen computed tomography excluded distant metastasis.. Primary SCCE (pT1bN1M0, IIB) was established after salvage operation.. The tumor was enlarged after 1 cycle of first-line chemotherapy using irinotecan plus cisplatin, which indicated drug resistance. Second-line oral apatinib (425 mg daily) plus S-1 (60 mg, twice daily for 4 weeks with a 2-week drug-free interval) for a month showed efficacy, as shown by decreased serum neuron-specific enolase and stable of the esophageal lesion. Thereafter, salvage minimally invasive Ivor-Lewis esophagectomy and 2-field lymph node dissection was performed, followed by oral apatinib plus S-1 at the prior dosage for 6 months. In addition, maintenance therapy using low-dose apatinib (250 mg daily) plus S-1 (40 mg, twice daily for 4 weeks with a 2-week interval) were administered for another 6 months. Then the patient was followed up irregularly at the outpatient clinic.. The adverse events including hand-foot syndrome, hypertension, vomiting, leukopenia, impaired hepatic function, and fatigue were mainly tolerable. Forty months after the operation, he was readmitted for back pain and disseminated bone metastases appeared in magnetic resonance images. His progression-free survival could not be obtained precisely, and his overall survival was longer than 40 months up to September 2019.. S-1 plus apatinib followed by a timely esophagectomy with curative intent might be an alternative option for chemotherapy-refractory SCCE in selected patients. Better evidence is warranted.

Effects of S-1 combined with radiotherapy in the treatment of advanced esophageal cancer: A systematic review and meta-analysis protocol.
Esophageal cancer is one of the worst malignant digestive neoplasms with poor treatment outcomes. Definitive concurrent chemoradiotherapy (CRT) has become the standard nonsurgical treatment option for locally advanced esophageal cancer. The chemotherapeutic drugs 5-fluorouracil and cisplatin have been most commonly used in CRT of esophageal cancer. However, radiotherapy combined with 5-FU/cisplatin often delivers severe toxicity to patients. S-1 as an oral chemotherapeutic drug exhibits higher anti-tumor activity, less adverse effects, and better biological availability. S-1 also has excellent effects as a CRT regimen for esophageal cancer.. A systematic literature search will be performed through January 2018 using MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and Google Scholar for relevant articles published in any language. Randomized controlled trials, prospective comparative studies will be included. All meta-analyses will be performed using Review Manager software. The quality of the studies will be evaluated using the guidelines listed in the Cochrane Handbook. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statements will be followed until the findings of the systematic review and meta-analysis are reported.. The results of this systematic review and meta-analysis will be published in a peer-reviewed journal.. Our study will draw an objective conclusion of the effects of S-1 combined with radiotherapy in the treatment of unresectable esophageal cancer and provide level I evidence for clinical decision makings.

Concurrent chemo-radiotherapy with S-1 as an alternative therapy for elderly Chinese patients with non-metastatic esophageal squamous cancer: evidence based on a systematic review and meta-analysis.
This systematic review and meta-analysis aims to systematically assess the effects of concurrent chemo-radiotherapy (CRT) compared with radiotherapy (RT) alone for elderly Chinese patients with non-metastatic esophageal squamous cancer.. We searched PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), China Biomedical Literature Database (CBM), and China National Knowledge Infrastructure (CNKI) databases. We retrieved randomized controlled trials on concurrent CRT with Gimeraciland Oteracil Porassium (S-1) compared with RT alone for aged Chinese patients with non-metastatic esophageal squamous cancer performed until August 2016.. Eight eligible studies involving 536 patients were subjected to meta-analysis. As a response rate measure, a relative risk (RR) of 1.37 [95% confidence intervals (CIs): 1.24, 1.53; P = 0.00], which reached statistical significance, was estimated when concurrent CRT with S-1 was performed compared with RT alone. Sensitivity analysis on response rate confirmed the robustness of the pooled result. The RR values of 1.44 (95% CIs: 1.22, 1.70; P = 0.00) and 1.77 (95% CIs: 1.26, 2.48; P = 0.00) estimated for 1- and 2-year survival rate indices, respectively, were also statistically significant. The incidence of adverse events was similar in both groups.. This review concluded that concurrent CRT with S-1 can improve the efficacy and prolong the survival period of elderly Chinese patients with non-metastatic esophageal squamous cancer and does not significantly increase the acute adverse effects of RT alone.

Capecitabine, 5-fluorouracil and S-1 based regimens for previously untreated advanced oesophagogastric cancer: A network meta-analysis.
As evidence is inconsistent and based on either isolated Asian or Western studies, we conducted a network meta-analysis (NMA) to examine efficacy and safety of 5-FU (5-fluorouracil), capecitabine and S-1-based first-line treatment of advanced esophagogastric cancer in Asian and Western patients. Medline, EMBASE, CENTRAL and conferences ASCO and ESMO were searched up to January 2016 for randomized-controlled-trials comparing 5-FU, capecitabine or S-1-based regimens with equal chemotherapy backbones. Direct and indirect data for overall survival (OS) and progression-free-survival (PFS) were combined on the Hazard Ratio (HR)-scale using random-effects NMA and calculated as combined HRs and 95%credible intervals (95%CrI). Grade 1-2 and grade 3-4 adverse events were compared with pair-wise meta-analysis. Fifteen studies were identified including capecitabine (n = 945), 5-FU (n = 2,132) or S-1 (n = 1,636). No differences were found in respectively OS and PFS for capecitabine-based versus 5-FU-based regimens (HR = 0.89, 95%CrI = 0.76-1.04 and HR = 0.98, 95%CrI = 0.75-1.32), S-1-based versus 5-FU-based regimens (HR = 0.92, 95%CrI = 0.82-1.04 and HR = 0.88, 95%CrI = 0.70-1.11) and S-1-based versus capecitabine-based regimens (HR = 1.03, 95%CrI = 0.87-1.22 and HR = 0.89, 95%CrI = 0.65-1.20). Effects were similar in Asian and Western subgroups. Toxicity profiles were different but a lower frequency of relevant adverse events was observed with S-1 In conclusion, as efficacy was similar, choosing fluoropyrimidines should be based on their individual toxicity profiles.

[Successful Multimodality Treatment Including Three-Stage Operation for Esophageal Cancer with Esophagorespiratory Fistula - A Case Report].
The esophagorespiratory fistula(ERF)is a fatal complication ofesophageal cancer, because ofadvanced oncological status and poor conditions due to pneumonia and/or malnutrition.We report here a case of patient who was successfully treated for esophageal cancer with ERF with multimodality therapy including three-stage operation. A 65-year-old woman ofesophageal cancer received preoperative chemotherapy, and developed EFR before operation. Prolonged conservative therapies for ERF let her general condition get worse. Therefore, the patient underwent esophagostomy and gastrostomy to recover her condition. She received chemo-radiotherapy followed by esophagectomy. And she was performed the reconstruction next month. She is still alive without recurrence at 20 months after resection. In previous reports, a total of 6 cases have been performed esophagectomy for esophageal cancer with ERF in Japan. Only one case was reported that had survived longer than 12 months. This multimodality therapy can be one ofthe best strategies for the patients ofesophageal cancer with ERF, even ifthey have poor condition.

The Efficacy and Safety of First-line Chemotherapy in Advanced Esophagogastric Cancer: A Network Meta-analysis.
A globally accepted standard first-line chemotherapy regimen in advanced esophagogastric cancer (AEGC) is not clearly established. We conducted a systematic review to investigate the efficacy and safety of first-line chemotherapy using Network meta-analysis (NMA).. Medline, EMBASE, CENTRAL, and conferences were searched until June 2015 for randomized controlled trials that compared regimens containing: fluoropyrimidine (F), platinum (cisplatin [C] and oxaliplatin [Ox]), taxane (T), anthracycline (A), irinotecan (I), or methotrexate (M). Direct and indirect evidence for overall survival (OS) and progression-free-survival (PFS) were combined using random-effects NMA on the hazard ratio (HR) scale and calculated as combined hazard ratios and 95% credible intervals (CrIs).. The NMA incorporated 17 chemotherapy regimens with 37 direct comparisons between regimens for OS (50 studies, n = 10 249) and 29 direct comparisons for PFS (34 studies, n = 7795). Combining direct and indirect effects showed increased efficacy for fluoropyrimidine noncisplatin doublets (F-doublets) over cisplatin doublets (C-doublets): FI vs CF (combined HR = 0.85, 95% CrI = 0.71 to 0.99), FOx vs CF (combined HR = 0.83, 95% CrI = 0.71 to 0.98) in OS and FOx vs CF (combined HR = 0.82, 95% CrI = 0.66 to 0.99) in PFS. Anthracycline-containing triplets (A-triplets: ACF, AFOx, AFM) and TCF triplet showed no benefit over F-doublets in OS and PFS. The triplet FOxT showed increased PFS vs F-doublets FT (combined HR = 0.61, 95% CrI = 0.38 to 0.99), FI (combined HR = 0.62, 95% CrI = 0.38 to 0.99), and FOx (combined HR = 0.67, 95% CrI = 0.44 to 0.99). Increased grade 3 to 4 toxicity was found for CF vs F-doublets, for ACF vs FI for TCF vs CF, and for FOxT vs FOx.. Based on efficacy and toxicity, F-doublets FOx, FI, and FT are preferred as first-line treatment for AEGC compared with C-doublets, A-triplets, and TCF. FOxT is the most promising triplet.

[Adjuvant treatment for esophagogastric junction cancer].
Conducting clinical trials to establish evidence of the benefits of adjuvant treatment for resectable esophagogastric junction (EGJ) cancer is difficult because it is a very rare disease compared with gastric or esophageal cancer. In the West, where esophageal cancer occurs more frequently than gastric cancer, a phase III trial (the CROSS trial) demonstrated the efficacy of preoperative chemoradiotherapy using carboplatin plus paclitaxel for patients with esophageal or EGJ cancer. Thus, this preoperative regimen is considered to be the standard adjuvant treatment for resectable EGJ cancer in the West. On the other hand, the Western evidence is not widely accepted in Asia because there are many differences in surgical techniques, particularly in the field of lymph node dissection, between the West and Asia. The standard adjuvant treatment for resectable EGJ cancer in Asia is postoperative chemotherapy using S-1 alone or capecitabine plus oxaliplatin based on the results of two large-scale phase III trials in gastric cancer conducted in East Asia. The incidence of EGJ cancer has recently increased in Japan, and nationwide studies to develop more effective adjuvant treatment for resectable EGJ cancer should be conducted in the near future.

[A patient with esophageal cancer recurrence responding to S-1 combined with cisplatin (CDDP)].
We administered a combination chemotherapy of S-1 plus cisplatin (CDDP) therapy to a patient with recurrenced cancer of esophagus in lymph node. S-1 (80 mg/m(2)/day), taken out of the capsule, was administered via the catheter for tube feeding on day 1 to day 21 and CDDP at 60 mg/m(2)/day by intravenous drip infusion on day 8 for 3 weeks followed by a drug-free 2 week period as the first course. After 2 courses, CT findings showed a complete regression of the lymph node for complete response (CR). He has been alive for 10 months without recurrence. Combined use of S-1 and CDDP is effective as chemotherapy for recurrenced esophageal cancer.

Medical treatment for advanced gastroesophageal adenocarcinoma.
Gastroesophageal cancers continue to pose a significant health burden around the world. Advanced gastroesophageal cancer is an incurable condition and more research is desirable. Considerable new and important information, however, has become available.. The number of phase III trials for patients with advanced gastroesophageal cancer is increasing and that is welcome news. Current results suggest that capecitabine can be substituted for 5-fluorouracil and oxaliplatin for cisplatin. Docetaxel, when combined with 5-fluorouracil and cisplatin, prolongs overall survival as well as improves safety, quality of life, and efficacy. S-1, a fourth generation oral fluoropyridine, is especially effective in combination with cisplatin. Dosing of S-1 is different between Western and Asian populations due to differences in metabolism by CYP2A6. Irinotecan should not be used as frontline therapy for advanced gastroesophageal cancer. Biologic agents are currently under investigation.. Safer, more convenient, and more effective chemotherapy combinations are being developed for patients with advanced gastroesophageal cancer; however, considerable challenges exist to select the optimal therapy for an individual patient.

[Recurrence of esophageal cancer treated by combination TS-1/CDDP therapy].
A 68-year-old man underwent subtotal esophagectomy with two fields lymphadenectomy and postoperative chemotherapy so called low dose FP therapy for advanced esophageal cancer (Stage IIIa, pT 3, pN 1, M 0) in October 1999. As he was diagnosed with a recurrence of esophageal cancer as metastatic lymph node tumors which were placed in the right anterocervical and supraclavicular region in March 2001, he underwent enucleation of metastatic lymph node tumors and postoperative chemoradiation therapy, so-called low-dose FP-R therapy. Recently, since other metastatic lymph node tumors in the neck appeared again in August 2001, he underwent radical neck lymph node dissection and postoperative chemoradiation treatment, so-called FAP-R therapy. In October 2003, a chest CT showed multiple lung tumors. He was diagnosed with multiple metastatic lung tumors originating from esophageal cancer. Then, two courses of a combined chemotherapy consisting of TS-1 and CDDP were administered at an interval of one month. We judged the effect of this chemotherapy to be a partial response (PR), because the largest metastatic lung tumor 18 mm in diameter showed a reduction rate of 81.9%, and other tumors had almost disappeared in the chest CT after the combined therapy. No severe adverse effects of more than grade 3 were observed during this combined therapy. This combined chemotherapy consisting of TS-1 and CDDP may prove effective for treating recurrent cases of esophageal cancer.

[Conceptual changes in cancer chemotherapy--biochemical modulation of 5-FU].
Recently, the demand for more useful therapies for cancer patients has increased. We describe in this paper a therapeutic modality based on a self-rescuing concept (SRC), and which features dual activity, i.e., an effect-enhancing activity and an adverse reaction-reducing activity. We present the theory and practice of S-1, a novel oral fluoropyrimidine anticancer agent designed to enhance anticancer activity and reduce gastrointestinal toxicity through the deliberate combination of the following components: the oral fluoropyrimidine agent tegafur; a DPD inhibitor (CDHP) which is more potent than uracil, which is used in UFT; and an ORTC inhibitor (Oxo) which localizes in the gastrointestinal tract. S-1 is a combination drug with a molar ratio of 1:0.4:1 in FT, CDHP, and Oxo, respectively. A clinical pharmacology study was conducted to examine blood concentrations of 5-FU after twice-a-day administration of S-1 at a dose of 40 mg/m2. Blood concentrations of 5-FU were found to be 60 to 200 ng/ml in all twelve patients examined. The overall response rate was 44.6% (45/101). In addition, the incidence of adverse reactions judged to be grade 3 or higher was 10% or less. We have also reported a combination therapy with 5-FU (civ) (5-FU: 250 to 350 mg/body, 24-hour cvi, consecutive days) and low-dose cisplatin (CDDP: 3 to 5 mg/body, i.v., 5 days/week), in which CDDP was used as a modulator of 5-FU. Low-dose FP therapy provided response rates as high as 40 to 60% in 163 patients with various gastrointestinal cancers other than pancreas cancer. The incidence of the adverse reactions of nausea and vomiting which were judged to be grade 3 or higher was 2.5% (4/163). The incidences of other adverse reactions were 1% or less. In line with the theory and practice of combination therapy with 5-FU (cvi) 24 hr cvi; 5-FU: 750 to 1,000 mg/body/day on Monday, Wednesday, and Friday (withdrawal on Tuesday, Thursday, Saturday and Sunday) intermittent administration and low-dose CDDP (3 to 5 mg/body/day day 1-5/w) consecutive administration was utilized in which there was a difference in cell cycle between gastrointestinal mucosal cell and tumor cell, or between bone marrow cell and tumor cell. Few adverse reactions, e.g., diarrhea and stomatitis, were observed despite the overall response rate being as high as 52.4% (22/42). The incidence of adverse reaction judged to be grade 3 or higher was as low as 9.3% (5/54), with an incidence of 9.3% (5/54) in Grade 3 or higher myelotox Topics: Administration, Oral; Antineoplastic Combined Chemotherapy Protocols; Cisplatin; Colonic Neoplasms; Drug Administration Schedule; Drug Combinations; Esophageal Neoplasms; Fluorouracil; Humans; Infusions, Intravenous; Oxonic Acid; Pancreatic Neoplasms; Pyridines; Rectal Neoplasms; Tegafur | 2000 |

Clinical efficacy and safety of apatinib combined with S-1 in advanced esophageal squamous cell carcinoma.
Background Esophageal cancer is a very common malignant tumor in China, especially esophageal squamous cell carcinoma (ESCC), but there is currently no effective treatment for patients after first-line chemotherapy failure. Apatinib has shown promising outcomes in treatment with various solid tumors. Objectives To evaluate the clinical efficacy and safety of apatinib combined with S-1 in the treatment of advanced ESCC patients after first-line chemotherapy failure. Methods In this prospective study, fifteen patients with advanced ESCC who failed first-line chemotherapy were enrolled from Nov 2016 to Apr 2019. Patients received the combination therapy with apatinib (250-500 mg, once daily) plus S-1 (40-60 mg based on body surface area, twice daily). Primary endpoint was progression-free survival (PFS). Secondary endpoints included overall survival (OS), disease control rate (DCR) and objective response rate (ORR). Adverse events (AEs) were recorded to evaluate the safety. Results A total of 12 patients were included in the efficacy analysis. The median PFS was 6.23 months, and the median OS was 8.83 months. Two (16.67%) patients achieved partial remission, 9 patients (75.00%) achieved stable disease and 1 (8.33%) patient achieved progressive disease. DCR and ORR was 91.67%and 16.67%, respectively. Most frequent AEs were hypertension, myelosuppression, weakness, hemorrhage, hand-foot syndrome, total bilirubin elevation, sick, proteinuria, oral ulcer, loss of appetite, and transaminase elevation. The most AEs were in grade I~II. Conclusion The combination therapy of apatinib plus S-1 was effective and well tolerated in the treatment of advanced ESCC patients after first-line chemotherapy failure. The combination therapy has the potential to be a potent therapeutic option for advanced ESCC patients after first-line chemotherapy failure.

Safety and efficacy of pembrolizumab in combination with S-1 plus oxaliplatin as a first-line treatment in patients with advanced gastric/gastroesophageal junction cancer: Cohort 1 data from the KEYNOTE-659 phase IIb study.
The KEYNOTE-659 study evaluated the efficacy and safety of pembrolizumab in combination with chemotherapy as the first-line treatment in Japanese patients with advanced gastric/gastroesophageal junction (G/GEJ) cancer. In this paper, we report results from cohort 1 (S-1 plus oxaliplatin [SOX] with pembrolizumab).. This was a non-randomised, multicentre, open-label phase IIb study in patients with advanced programmed death-ligand 1 (PD-L1)-positive, human epidermal growth factor receptor 2-negative G/GEJ tumours. The primary endpoint was the objective response rate (ORR) assessed by blinded independent central review (BICR). Secondary endpoints were duration of response (DOR), disease control rate (DCR), time to response (TTR), progression-free survival (PFS), overall survival (OS) and safety. Exploratory analyses were performed based on the PD-L1 combined positive score (CPS) status.. Fifty-four patients were evaluated. The median follow-up was 10.1 months. ORR and DCR by BICR were 72.2% (95% confidence interval [CI] 58.4-83.5) and 96.3% (95% CI 87.3-99.5), respectively. Median DOR, TTR, PFS and OS were as follows: not reached, 1.5 months, 9.4 months and not reached. The ORR was 73.9% in patients with CPS ≥1 to <10 and 71.0% in those with CPS ≥10. Grade ≥3 treatment-related adverse events (TRAEs) were reported by 57.4% of patients. The most common grade ≥3 TRAEs were decreased platelet count (14.8%), decreased neutrophil count (13.0%), colitis (5.6%) and adrenal insufficiency (5.6%).. SOX with pembrolizumab showed encouraging efficacy and a manageable safety profile for the first-line treatment of advanced G/GEJ cancer.. NCT03382600/JapicCTI-183829.

An Open-Label Single-Arm Phase II Study of Treatment with Neoadjuvant S-1 Plus Cisplatin for Clinical Stage III Squamous Cell Carcinoma of the Esophagus.
Two courses of neoadjuvant therapy using S-1 plus cisplatin for clinical stage III esophageal squamous cell carcinoma did not achieve expected response rate according to endoscopic evaluation of primary tumors. Subsequent esophagectomy was safely performed.. In Japan, esophagectomy after two courses of 5-fluorouracil plus cisplatin is regarded a standard strategy for treating stage II or III esophageal squamous cell carcinoma (ESCC). However, 5-fluorouracil plus cisplatin does not benefit cohorts with clinical stage III ESCC, suggesting the need for a more effective regimen.. A single-arm, open-label phase II trial was conducted to evaluate the safety and efficacy of two courses of neoadjuvant chemotherapy using S-1 plus cisplatin (NAC-SP) for clinical stage III ESCC. The primary endpoint was overall response rate as defined by endoscopic evaluation of primary tumors.. We enrolled 26 patients. The completion rate for the two courses of NAC-SP was 61.5%. Grade 3 or higher adverse events were experienced by 38.4% of patients. The treatment response rate according to endoscopic findings, acquired before the second course, was 34.6% and below the expected level (55.0%). The morbidity rate of patients who underwent radical subtotal esophagectomy (96.2%) was 32.0%. Repeat surgery was unnecessary, and surgery-associated deaths did not occur. The 5-year progression-free survival (PFS) and overall survival (OS) rates were 84.6% and 92.2%, respectively.. We demonstrate safety of NAC-SP, but not its efficacy, for patients with clinical stage III ESCC. Subsequent esophagectomy was safely performed.

Phase II Study of S-1 plus Cisplatin as First-Line Therapy in Patients with Metastatic Esophageal Carcinoma.
Patients with metastatic esophageal squamous cell cancer (ESCC) need safer and more efficacious treatments. The aim of this phase II study was to investigate the efficacy and safety of S-1 plus cisplatin as first-line therapy in metastatic ESCC.. 50 patients with metastatic ESCC who had not received prior systemic chemotherapy for metastatic disease were enrolled. Patients received S-1 at 40 mg/m2 divided into 2 daily doses for 14 days and cisplatin at 75 mg/m2 on day 1 or 25 mg/m2 on days 1-3 intravenously, repeated every 21 days with a maximum of 6 cycles.. 47 patients were assessable for response and 18 patients achieved a partial response, giving an overall response rate of 38.3%. Among those who had objective responses, a large percentage (72.2%) quickly showed remarkable tumor shrinkage during the first 2 cycles. 18 (38.3%) patients had stable disease. The median progression-free survival was 5.6 months, and the median overall survival was 12.0 months. Toxicity was mild to moderate and generally tolerable.. The combination of S-1 plus cisplatin was a well-tolerated and convenient chemotherapy regimen with promising efficacy.

Irinotecan plus S-1 versus S-1 in patients with previously treated recurrent or metastatic esophageal cancer (ESWN 01): a prospective randomized, multicenter, open-labeled phase 3 trial.
The benefit of systemic treatments in esophageal squamous cell carcinoma (ESCC) which has progressed after chemotherapy is still uncertain and optimal regimens based on randomized trials have not yet been established. We aimed to compare the efficacy of irinotecan plus S-1 with S-1 monotherapy in recurrent or metastatic ESCC patients who had resistance to platinum- or taxane-based chemotherapy.. Between December 23, 2014 and July 25, 2016, we screened 148 patients and randomly assigned 123 patients to receive either irinotecan plus S-1 regimen (n = 61) or S-1 monotherapy (n = 62). After a median follow-up of 29.2 months (95% confidence interval [CI] 17.5-40.9 months), the median PFS was significantly longer in the irinotecan plus S-1 group than in the S-1 monotherapy group (3.8 months [95% CI 2.9-4.3 months] vs. 1.7 months [95% CI 1.4-2.7 months], hazard ratio = 0.58, 95% CI 0.38-0.86, P = 0.006). The objective response rates were 24.6% in the irinotecan plus S-1 group and 9.7% in the S-1 monotherapy group (P = 0.002). The patients in the irinotecan plus S-1 group presented with increased rates of grade 3-4 leukopenia (16.4% vs. 0%), neutropenia (14.8% vs. 1.6%), and nausea (4.9% vs. 0%). No significant difference in grade 3-4 diarrhea and no treatment-related deaths were observed in both groups.. The combination of irinotecan with S-1 was similarly tolerable but significantly prolonged PFS compared to S-1 monotherapy as a second- or third-line treatment in patients with recurrent or metastatic ESCC.

A multicenter phase III study comparing Simultaneous Integrated Boost (SIB) radiotherapy concurrent and consolidated with S-1 versus SIB alone in elderly patients with esophageal and esophagogastric cancer - the 3JECROG P-01 study protocol.
The importance of definitive radiotherapy for elderly patients with esophageal and esophagogastric-junction cancer is pronounced. However, little is known in terms of the best way to combine radiotherapy with other treatment options. This study aims to compare the efficiency of SIB radiotherapy alone with SIB radiotherapy concurrent and consolidated with S-1 for elderly patients. Comprehensive geriatric assessment is also incorporated in the procedure of treatment.. The study is a two arm, open, randomized multicenter Phase III trial with patients over 70 years old with stage IIA-IVB (UICC 2002, IVB only with metastasis to supraclavicular or celiac lymph nodes) squamous cell carcinoma or adenocarcinoma of esophagus or gastroesophageal junction. A total of 300 patients will be randomized using a 1:1 allocation ratio stratified by disease stage and study site. Patients allocated to the SIB arm will receive definitive SIB radiotherapy (95%PTV/PGTV 50.4Gy/59.92Gy/28f) while those randomized to SIB + S-1 arm will receive definitive SIB radiotherapy concurrent and consolidated with S-1. The primary endpoint of the trial is 1-year overall survival. Secondary objectives include progression-free survival, recurrence-free survival (local-regional and distant), disease failure pattern, toxicity profile as well as quality of life. Besides, detailed radiotherapy protocol and quality assurance procedure have been incorporated into this trial.. The proportion of elderly patients in esophageal cancer is now growing, but there is a lack of evidence in term of treatment standard for this group of patients, which is what we aim to obtain through this prospective phase III study.. clinicaltrials.gov NCT02979691 .

Study protocol of a randomized phase III trial of comparing preoperative chemoradiation with preoperative chemotherapy in patients with locally advanced gastric cancer or esophagogastric junction adenocarcinoma: PREACT.
The prognosis of patients with locally advanced gastric cancer or esophagogastric junction adenocarcinoma is still dismal. There are no standard treatment strategies for these patients. Multidisciplinary team (MDT) approach is a good choice for making a high-quality decision. Generally, MDT will recommend these patients to receive preoperative chemotherapy or preoperative chemoradiation based on all kinds of treatment guidelines. However, the preferred preoperative treatment is still not established. In order to solve this problem, we carry out this randomized phase III trial of comparing preoperative chemoradiation with preoperative chemotherapy in patients with locally advanced gastric cancer or esophagogastric junction adenocarcinoma.. Eligible patients with locally advanced gastric cancer or esophagogastric junction adenocarcinoma are randomized to receive preoperative chemoradiation or preoperative chemotherapy, followed by surgery and postoperative chemotherapy. In the preoperative chemoradiation arm (Pre-CRT), patients receive two cycles of S-1 and oxaliplatin (SOX), chemoradiation, then followed by surgery and three more cycles of SOX chemotherapy. In the preoperative chemotherapy arm (Pre-CT), patients receive three cycles of SOX, following surgery three more cycles of SOX are given. The primary endpoint of this trial is to verify that preoperative chemoradiation could significantly improve the 3-year disease free survival (DFS) of patients with locally advanced gastric cancer or esophagogastric junction adenocarcinoma compared to preoperative chemotherapy.. The results from this trial will provide important information about whether preoperative chemoradiation could improve survival compared to preoperative chemotherapy among patients with locally advanced gastric cancer or esophagogastric junction adenocarcinoma..

Phase I/II Trial of Chemotherapy with Docetaxel, Cisplatin, and S-1 for Unresectable Advanced Squamous Cell Carcinoma of the Esophagus.
Our previous trial with a docetaxel, cisplatin, and 5-fluorouracil (DCF) regimen showed high response rates in metastatic squamous cell carcinoma of the esophagus (SCCE). The observed increased toxicity of the DCF regimen, however, was clinically harmful. S-1, an oral anticancer drug, has been approved as a combination therapy for SCCE, and alternate-day regimen with S-1 has shown lower levels of toxicity. This prospective single-center phase I/II trial examines the efficacy and toxicity of a combination of docetaxel, cisplatin, and an alternate-day regimen of S-1 (modified DCS) for patients with metastatic SCCE. We use a two-stage design. Phase I is undertaken to determine the maximum tolerated dose and the recommended dose. The phase I trial adopts a three-patient cohort with escalating dose study design. In the phase II trial, the primary endpoint is the assessment of the overall response rate (Response Evaluation Criteria in Solid Tumors 1.1). The secondary endpoints are the evaluation of drug-related toxicity (National Cancer Institute Common Toxicity Criteria 4.0), overall survival, and progression-free survival. Fifty patients with metastatic SCCE participate in the phase II section. This study protocol is the first to test the effects of the modified DCS regimen for metastatic SCCE.

Comparative study of cisplatin-based definitive concurrent chemoradiotherapy with S-1 versus paclitaxel for unresectable locally advanced esophageal squamous cell carcinoma.
This study compared the efficiency and safety of definitive concurrent chemoradiotherapy (CCRT) using Paclitaxel plus Cisplatin (TP) versus S-1 plus Cisplatin (CS) in unresectable locally advanced esophageal squamous cell carcinoma (LAESCC). Between January 2009 and December 2013, 203 LAESCC patients were retrospectively reviewed. We performed a propensity score matching analysis; 41 patients treated with the CS regimen were matched 1:1 to patients who received the TP regimen. Patient- and disease-related characteristics were well-balanced between the two groups. The CS group showed significantly better treatment compliance (90.2% vs. 70.7%, P = 0.026) and less hospital stay (48 days vs 49 days, P = 0.025) over the TP group during the CCRT course. The complete response rate was comparable between the two groups (51.2% vs. 48.8%, P = 0.825). The 1- and 3-year overall survival (OS) rates in the TP group were 63.4% and 32.4% compared to 62.8% and 32.1% in the CS group, respectively (P = 0.796). The 1- and 3-year progression-free survival (PFS) rates in the TP group were 51.2% and 24.9%, compared to 53.6% and 18.9% in the CS group, respectively (P = 0.630). The incidence of severe and total neutropenia in the TP group was significantly higher compared to the CS group (P = 0.011 and 0.046, respectively). Multivariate analysis revealed that T stage and the complete response rate were strong prognostic factors associated with OS and PFS. In conclusion, both treatment regimens yielded satisfactory survival outcomes, but the CS regimen could significantly improve treatment compliance, reduce hematological toxicities and lengths of hospital stay. Future prospective studies in large cohorts are highly warranted to confirm the findings in our report.

S-1 versus S-1 plus cisplatin concurrent intensity modulated radiation therapy in the treatment of esophageal squamous cell carcinoma: Study protocol for a randomized controlled phase II trial.
Chemotherapy regimens are often a 2-drug regimen in concurrent chemotherapy and radiotherapy for esophageal cancer (EC). However, some retrospective studies have suggested that for patients with EC receiving radiotherapy combined with 2-drug chemotherapy have the severe toxicity. And S-1 alone with the combination of radiotherapy treatment effect is good, and achieved good clinical remission rate. The purpose of this trial is compare the efficacy and toxicity of combining S-1 or S-1 plus cisplatin with radiotherapy for esophageal squamous cell carcinoma.. The study is a randomized, controlled, multicenter trial, comparing S-1 versus S-1 plus cisplatin concurrent radiotherapy for patients with esophageal squamous cell carcinoma. Eighty-eight patients with unresectable or medically unfit for surgery esophageal squamous cell carcinoma (clinical stage I to III), will randomly assigned to receive four cycles (2 concomitant and 2 postradiotherapy) S-1 or S-1 plus cisplatin along with radiotherapy 60-66 Gy/30 to 33 fractions. The primary outcome is complete response rate of primary tumor which will be measured by endoscopy and computer screen at 3 months after the completion of treatment. Secondary outcomes include survival and toxicity.. To our knowledge, this study protocol is the first to test the effect between S-1 versus S-1 plus cisplatin concurrent intensity modulated radiation therapy in the treatment of esophageal squamous cell carcinoma. If the result will be the same effect and fewer side effects and less costly in S-1 plus radiotherapy. It will supply more treatment selection for esophageal squamous cell carcinoma.

Phase II trial of neoadjuvant chemotherapy with docetaxel, nedaplatin, and S1 for advanced esophageal squamous cell carcinoma.
Although standard chemotherapy for esophageal cancer patients is fluorouracil and cisplatin, the prognosis is still unsatisfactory. A new therapeutic regimen combining docetaxel, cisplatin, and 5-fluorouracil was recently developed to improve both local and distant tumor control. We developed a new regimen of docetaxel, nedaplatin, and S1 (DGS) and previously reported the recommended dose in a phase I dose-escalation study. We then undertook a phase II study of DGS for advanced esophageal squamous cell carcinoma. Patients with clinical stage IB/II/III disease were eligible. Patients received two courses of chemotherapy: docetaxel 35 mg/m(2) with nedaplatin 40 mg/m(2) on day 8, 80 mg/m(2) S1 on days 1-14, and 2 weeks off. After completion of chemotherapy, patients underwent esophagectomy. The primary endpoint was the completion rate of protocol treatment (completion of two courses of preoperative chemotherapy and R0 surgery [no residual tumor]). We enrolled 32 patients. The completion rate of protocol treatment was 96.9%. During chemotherapy, the most common grade 3 or 4 toxicity was neutropenia (25.0%). No treatment-related deaths were observed, and the incidence of operative morbidity was tolerable. The overall response rate after chemotherapy was 83.3%. This DGS regimen was well tolerated and highly active. This trial is registered with the University Hospital Medical Information Network (UMIN ID: 000014626).

Randomized phase 2 trial of S1 and oxaliplatin-based chemoradiotherapy with or without induction chemotherapy for esophageal cancer.
To assess, in a randomized, phase 2 trial, the efficacy and safety of chemoradiotherapy with or without induction chemotherapy (ICT) of S1 and oxaliplatin for esophageal cancer.. Patients with stage II, III, or IVA esophageal cancer were randomly allocated to either 2 cycles of ICT (oxaliplatin 130 mg/m(2) on day 1 and S1 at 40 mg/m(2) twice daily on days 1-14, every 3 weeks) followed by concurrent chemoradiotherapy (CCRT) (46 Gy, 2 Gy/d with oxaliplatin 130 mg/m(2) on days 1 and 21 and S1 30 mg/m(2) twice daily, 5 days per week during radiation therapy) and esophagectomy (arm A), or the same CCRT followed by esophagectomy without ICT (arm B). The primary endpoint was the pathologic complete response (pCR) rate.. A total of 97 patients were randomized (arm A/B, 47/50), 70 of whom underwent esophagectomy (arm A/B, 34/36). The intention-to-treat pCR rate was 23.4% (95% confidence interval [CI] 11.2-35.6%) in arm A and 38% (95% CI 24.5% to 51.5%) in arm B. With a median follow-up duration of 30.3 months, the 2-year progression-free survival rate was 58.4% in arm A and 58.6% in arm B, whereas the 2-year overall survival rate was 60.7% and 63.7%, respectively. Grade 3 or 4 thrombocytopenia during CCRT was more common in arm A than in arm B (35.4% vs 4.1%). The relative dose intensity of S1 (89.5% ± 20.6% vs 98.3% ± 5.2%, P=.005) and oxaliplatin (91.4% ± 16.8% vs 99.0% ± 4.2%, P=.007) during CCRT was lower in arm A compared with arm B. Three patients in arm A, compared with none in arm B, died within 90 days after surgery.. Combination chemotherapy of S1 and oxaliplatin is an effective chemoradiotherapy regimen to treat esophageal cancer. However, we failed to show that the addition of ICT to the regimen can improve the pCR rate.

Clinical Benefit and Health-Related Quality of Life Assessment in Patients Treated with Cisplatin/S-1 Versus Cisplatin/5-FU: Secondary End Point Results From the First-Line Advanced Gastric Cancer Study (FLAGS).
Patient-reported outcomes (PRO) of health-related quality of life (HRQoL) and time to worsening of clinical benefit parameters were evaluated as secondary end points in the phase 3 first-line advanced gastric cancer study (FLAGS) trial of cisplatin/S-1 versus cisplatin/5-fluorouracil (5-FU) in patients with previously untreated advanced gastric cancer.. The primary PRO end point was the Trial Outcome Index of the Functional Assessment of Cancer Therapy-Gastric (FACT-Ga). FACT-Ga was completed at the beginning of the first 4 cycles, cycle 6, and then every 3 cycles thereafter. The Chemotherapy Convenience and Satisfaction Questionnaire (CCSQ) was administered before the first 4 cycles; clinical benefit parameters (performance status, weight loss, and anorexia) were assessed at baseline, prior to study drug administration on day 1 of each cycle after cycle 1, and at the end of study treatment.. Compliance to questionnaire fulfillment was more than 80 % through cycle 9. Significantly, fewer patients treated with cisplatin/S-1 reported worsened physical well-being (PWB) scores (45.1 versus 51.7 %, p = 0.044) and experienced significantly longer time to worsening in PWB scores, with a median of 4.5 months (95 % confidence interval (CI), 3.1-5.1) compared to 3.0 months (2.8-4.6) with cisplatin/5-FU (CF) (p = 0.01). Patients receiving cisplatin/S-1 also reported significantly higher best and worst score of PWB as well as CCSQ scores and a longer median time to worsening in clinical benefit parameters.. Differences in secondary end points of PWB, CCSQ scores, and clinical benefit parameters favoring the cisplatin/S-1 arm provide further evidence for considering this combination a standard therapeutic option for first-line treatment of advanced gastric cancer.

Phase I/II trial of chemoradiotherapy with concurrent S-1 and cisplatin for clinical stage II/III esophageal carcinoma (JCOG 0604).
We carried out a phase I/II trial of chemoradiotherapy concurrent with S-1 and cisplatin to determine the maximum tolerated dose and recommended dose and to evaluate the efficacy and safety of this treatment in patients with esophageal carcinoma. Thoracic esophageal cancer patients with clinical stage II/III disease, excluding T4, were eligible. Chemotherapy consisted of S-1 at a dose of 60-80 mg/m(2) /day on days 1-14, and cisplatin at 75 mg/m(2) on day 1, repeated twice every 4 weeks. Single daily radiation of 50.4 Gy was given in 28 fractions concurrently starting on day 1. Patients achieving an objective response after chemoradiotherapy underwent two additional cycles of chemotherapy. Patient accrual was terminated early due to slow enrolment after 44 patients were accrued. In the phase I part, two of six patients experienced dose-limiting toxicities at each level of S-1 (S-1 60 or 80 mg/m(2) /day). Considering treatment compliance, the recommended dose was determined to be S-1 60 mg/m(2) /day. The complete response rate, the primary endpoint of phase II, was 59.5% (22/37; 90% confidence interval, 44.6-73.1%; weighted threshold, 57.2%; P = 0.46 by the exact binomial test) on central review. In the phase II part, 3-year progression-free survival was 48.4%, with a 3-year overall survival of 61.9%. Grade 3 or 4 toxicity in phase II included leukopenia (57.9%), neutropenia (50%), hyponatremia (28.9%), anorexia (21.1%), anemia (18.4%), thrombocytopenia (18.4%), and febrile neutropenia (2.6%). No treatment-related deaths were observed. Although this combination showed acceptable toxicity and favorable 3-year survival, the study did not meet its primary endpoint.

A randomized Phase II trial of systemic chemotherapy with and without trastuzumab followed by surgery in HER2-positive advanced gastric or esophagogastric junction adenocarcinoma with extensive lymph node metastasis: Japan Clinical Oncology Group study JC
Pre-operative chemotherapy with S-1 plus cisplatin is considered to be acceptable as one of the standard treatment options for gastric cancer patients with extensive lymph node metastases in Japan. Addition of trastuzumab to chemotherapy is shown to be effective for HER2-positive advanced gastric cancer patients, and we have commenced a randomized Phase II trial in March 2015 to evaluate S-1 plus cisplatin plus trastuzumab compared with S-1 plus cisplatin alone in the neoadjuvant setting for HER2-positive gastric cancer patients with ELM, which are followed by adjuvant chemotherapy with S-1 for 1 year. A total of 130 patients will be accrued from 41 Japanese institutions over 3 years. The primary endpoint is overall survival. The secondary endpoints are progression-free survival, response rate of pre-operative chemotherapy, proportion of patients with R0 resection, proportion of patients who complete the pre-operative chemotherapy and surgery, proportion of patients who complete the protocol treatment including post-operative chemotherapy, pathological response rate and adverse events.

A prospective phase II trial of S-1 and cisplatin-based chemoradiotherapy for locoregionally advanced esophageal cancer.
S-1 is a novel oral fluoropyrimidine anticancer agent designed to enhance clinical efficacy, reduce gastrointestinal toxicity, and enhance radiotherapy effectiveness. A phase II trial was conducted to evaluate the efficacy and safety of preoperative chemoradiation with S-1 and cisplatin in locoregionally advanced esophageal cancer.. Eligible patients had stage IIA-IVA esophageal cancer. Patients received two cycles of S-1 (days 1-14 and days 22-35) and cisplatin (days 1 and 22) with concurrent radiotherapy (50.4 Gy total; 1.8 Gy/fraction). Esophagectomy was performed between weeks 12 and 18 as determined by the specialist multidisciplinary team.. Sixty patients were enrolled in this study between March 2008 and August 2011, and 59 were eligible. The clinical stage was ≥T3 in 28 patients (47 %) and N1 in 43 patients (72 %), with squamous cell carcinoma histology in 58 patients (97 %). Fifty-four patients (90 %) completed the planned chemoradiation. After chemoradiation, the clinical tumor response rate was 64.4 %. The primary toxicities included neutropenia (24 %) and esophagitis (8.5 %). Three treatment-related deaths were noted. Twenty-five patients (42 %) underwent esophagectomy following chemoradiation, and 15 achieved complete pathologic regression. The estimated overall survival and progression-free survival rates after 2 years were 65 and 48 %, respectively.. Concurrent chemoradiation with S-1 and cisplatin exhibited encouraging results with complete pathologic regression. The survival data were promising compared with the historical data of 5FU/cisplatin and should be confirmed in a randomized phase III trial. Toxicities were significant but clinically manageable.

Concurrent chemoradiotherapy with a novel fluoropyrimidine, S-1, and cisplatin for locally advanced esophageal cancer: long-term results of a phase II trial.
A phase II study was performed to investigate the safety and efficacy of concurrent chemoradiotherapy (CCRT) combined with an orally active fluoropyrimidine, S-1, plus cisplatin for locally advanced esophageal cancer (LAEC).. CCRT comprised 2 courses, a 30-Gy radiotherapy over 3 weeks plus daily oral S-1 (80 mg/m(2)/day) for 2 weeks and a 24-hour cisplatin infusion (70 mg/m(2)) on day 8, and an identical course administered after a 2-week break.. One hundred and sixteen patients, 12 with stage II, 71 with stage III, and 33 with stage IVa LAEC participated, and 106 of them (91.4%) completed the CCRT course. The most serious toxicity was myelosuppression: grade 3 and 4 neutropenia occurred in 28.4 and 9.5% of patients, respectively. Nonhematologic toxicity was moderate. Complete response rates in patients with stage II, III, and IVa LAEC were 91.7, 67.6, and 36.4%, respectively. The overall median survival time was 2.3 years and that of patients with stage II, III, and IVa cancer was 7.0, 2.6, and 1.3 years, respectively.. CCRT combined with S-1 plus cisplatin showed promising safety and efficacy. Potentially, this combination therapy could become a baseline medication for patients with LAEC.

Combination of cisplatin/S-1 in the treatment of patients with advanced gastric or gastroesophageal adenocarcinoma: Results of noninferiority and safety analyses compared with cisplatin/5-fluorouracil in the First-Line Advanced Gastric Cancer Study.
The aim of developing oral fluorouracil (5-FU) is to provide a more convenient administration route with similar efficacy and the best achievable tolerance. S-1, a novel oral fluoropyrimidine, was specifically designed to overcome the limitations of intravenous fluoropyrimidine therapies.. A multicentre, randomised phase 3 trial was undertaken to compare S-1/cisplatin (CS) with infusional 5-FU/cisplatin (CF) in 1053 patients with untreated, advanced gastric/gastroesophageal adenocarcinoma. This report discusses a post-hoc noninferiority overall survival (OS) and safety analyses.. Results (1029 treated; CS = 521/CF = 508) revealed OS in CS (8.6 months) was statistically noninferior to CF (7.9 months) [hazard ratio (HR) = 0.92 (two-sided 95% confidence interval (CI), 0.80-1.05)] for any margin equal to or greater than 1.05. Statistically significant safety advantages for the CS arm were observed [G3/4 neutropenia (CS, 18.6%; CF, 40.0%), febrile neutropenia (CS, 1.7%; CF, 6.9%), G3/4 stomatitis (CS, 1.3%; CF, 13.6%), diarrhoea (all grades: CS, 29.2%; CF, 38.4%) and renal adverse events (all grades: CS, 18.8%; CF, 33.5%)]. Hand-foot syndrome, infrequently reported, was mainly grade 1/2 in both arms. Treatment-related deaths were significantly lower in the CS arm than the CF arm (2.5% and 4.9%, respectively; P<0.047).. CS is noninferior to CF with a better safety profile and provides a new treatment option for patients with advanced gastric carcinoma.

A phase II study of neoadjuvant docetaxel, oxaliplatin, and S-1 (DOS) chemotherapy followed by surgery and adjuvant S-1 chemotherapy in potentially resectable gastric or gastroesophageal junction adenocarcinoma.
Adjuvant chemotherapy trial of TS-1 for gastric cancer study demonstrated that postoperative S-1 chemotherapy for 1 year improved overall survival of locally advanced gastric cancer (LAGC) patients. The goals of this study were to evaluate the feasibility and efficacy of neoadjuvant docetaxel, oxaliplatin, and S-1 (DOS) chemotherapy followed by surgery and adjuvant S-1 chemotherapy.. In this single-center, open-label, phase II study, patients with potentially resectable adenocarcinoma of the stomach or gastroesophageal junction were eligible. For neoadjuvant chemotherapy, docetaxel 50 mg/m(2) on day (D) 1, oxaliplatin 100 mg/m(2) on D1, and S-1 40 mg/m(2) bid orally on D1-14 were administrated every 3 weeks for three cycles. After DOS chemotherapy, gastrectomy was performed, and then, adjuvant S-1 40 mg/m(2) bid was given on D1-28 every 6 weeks for 1 year. The primary endpoints were the proportion of patients who did not experience grade 3 or 4 toxicities (except grade 3 neutropenia) and R0 resection rates.. A total of 41 patients were enrolled. All patients completed three planned cycles of neoadjuvant chemotherapy without disease progression. Eighteen patients (43.9 %) did not experience any grade 3-4 toxicity (except grade 3 neutropenia) during the neoadjuvant chemotherapy. All patients underwent surgery, and R0 resection was achieved in 40 patients (97.6 %).. Neoadjuvant DOS chemotherapy could be performed safely with a high R0 resection rate in LAGC patients. A phase III trial is currently underway.

More effective regimens are urgently needed for treatment of esophageal carcinoma; therefore, we conducted a phase I trial of a combination of docetaxel, nedaplatin, and S-1 (DGS) to determine the optimal dose in patients with advanced esophageal carcinoma.. We studied 14 patients with previously untreated advanced cervical esophageal carcinoma with T3-4 tumors and/or M1 staging and esophageal carcinoma with cervical lymph node metastasis. The patients received an infusion of docetaxel at different dose levels (levels 1, 2, 3, 4: 25, 30, 35, 40 mg/m(2), respectively) and an infusion of nedaplatin (40 mg/m(2)) on day 8 plus oral administration of S1 (80 mg/m(2)/day) for two consecutive weeks at two-week intervals.. Dose-limiting toxicities (DLTs) included febrile neutropenia and leukopenia. DLTs occurred in 2 out of 5 patients at level 4. The response rate was 78.6 (11/14)%, including a complete response rate of 35.7(5/14)%.. The DGS regimen reported here was well tolerated and toxicities were manageable. The maximum tolerated dose was level 4, and the recommended dose was determined to be docetaxel at 35 mg/m(2) with nedaplatin at 40 mg/m(2) plus S1 at 80 mg/m(2). We found that our regimen, administered on an outpatient basis, showed high activity and tolerance. A phase II study has been started.

Multicenter phase III comparison of cisplatin/S-1 with cisplatin/infusional fluorouracil in advanced gastric or gastroesophageal adenocarcinoma study: the FLAGS trial.
Patients with advanced gastric or gastroesophageal adenocarcinoma need more efficacious and safer treatments than established today. S-1, a contemporary oral fluoropyrimidine, can provide that advantage.. This study was conducted in 24 countries and 146 centers. One thousand fifty-three patients were stratified (center, number of metastatic sites, prior adjuvant therapy, and measurable cancer) and randomly assigned. Patients received either S-1 at 50 mg/m(2) divided in two daily doses for 21 days and cisplatin at 75 mg/m(2) intravenously on day 1, repeated every 28 days (527 patients) or infusional fluorouracil at 1,000 mg/m(2)/24 hours for 120 hours and cisplatin at 100 mg/m(2) intravenously on day 1, repeated every 28 days (526 patients). The primary end point was superiority in overall survival (OS) from cisplatin/S-1 compared with cisplatin/infusional fluorouracil in patients with advanced, untreated gastric, or gastroesophageal adenocarcinoma. The secondary end points were response rate, progression-free survival, time to treatment failure, and safety.. The median OS was 8.6 months in the cisplatin/S-1 arm and 7.9 months in the cisplatin/infusional fluorouracil arm (HR, 0.92; 95% CI, 0.80 to 1.05; P = .20). Significant safety advantages were observed in the cisplatin/S-1 arm compared with the cisplatin/infusional fluorouracil arm for the rates of grade 3/4 neutropenia (32.3% v 63.6%), complicated neutropenia (5.0% v 14.4%), stomatitis (1.3% v 13.6%), hypokalemia (3.6% v 10.8%), and treatment-related deaths (2.5% v 4.9%; P < .05).. Cisplatin/S-1 did not prolong OS of patients with advanced gastric or gastroesophageal adenocarcinoma compared with cisplatin/infusional fluorouracil, but it did result in a significantly improved safety profile.

Concurrent chemoradiotherapy with S-1 and cisplatin in advanced esophageal cancer.
How best to manage advanced esophageal cancer remains unresolved, especially in palliative care. Here, in a pilot study, we evaluated the efficacy and safety of concurrent chemoradiotherapy with S-1 and cisplatin in advanced esophageal cancer. Patients with locally advanced or metastatic squamous cell carcinoma of the esophagus received S-1 and cisplatin at doses of 70 mg/m(2)/day for 14 days and 70 mg/m(2) on day 1, respectively, every 3 weeks. Concurrently, radiotherapy was started at a dose of 200 cGy/day, up to a total of 5400 cGy. After concurrent chemoradiotherapy, additive chemotherapy was repeated up to six cycles. Thirty patients were enrolled in this study; of the 27 in whom efficacy could be evaluated, an objective response rate was seen in 20 (74.1%), including five (18.5%) complete pathologic responses in primary lesions. Improvement of dysphagia was seen in 21 (76%) patients. In patients with stage II or III esophageal cancer, the median progression-free survival and overall survival were 10.6 +/- 0.6 months (95% CI: 9.4-11.8) and 23.0 +/- 5.1 months (95% CI: 13.0-32.9), respectively. In patients with stage IV esophageal cancer, the median progression-free survival and overall survival were 5.4 +/- 1.6 months (95% CI: 2.2-8.6) and 11.6 +/- 1.6 months (95% CI: 8.4-14.8), respectively. The main hematological toxicity was neutropenia, but no neutropenic fever was observed. The major non-hematological toxicities were asthenia and vomiting, mostly of grades 1 and 2. Thus, concurrent chemoradiotherapy with S-1 and cisplatin may be a promising nonsurgical treatment in advanced esophageal cancer.

[Radiotherapy combined with S-1 and cisplatin for locally advanced and metastatic esophageal cancer].
Chemoradiotherapy combined with 5-fluorouracil and cisplatin have been effective for the treatment of advanced esophageal cancer, but superior treatments are needed. We prospectively analyzed the efficacy of concurrent chemoradiotherapy using oral fluoropyrimidine (S-1) and cisplatin for the treatment of advanced esophageal cancer.. The treatment protocol was determined on a phase I study. The first chemoradiotherapy course consisted of 30 Gy over 3 weeks, a daily oral administration of S-1 (80 mg/m2/day) for 2 weeks, and a 24-hour infusion of cisplatin (70 mg/M2) on day 8. A second course of chemoradiotherapy was performed after an interval of 2 weeks.. Seventy-one patients entered to this phase II study for five years (stage II: n=6, stage III: n=40, stage IV: n=25). All the stage II patients obtained a complete response, while 55% and 93% of the stage III patients and 20% and 76% of the stage IV patients obtained complete and partial responses, respectively. The major toxicity was myelosuppression. Eight patients (11%)developed a grade 4 leukocytopenia. The median survival times were thirty-nine months and eleven months for the stage II + stage III and stage IV patients, respectively.. Chemoradiotherapy combined with S-1 and cisplatin may be a promising treatment option for advanced esophageal cancer.

[A phase I/II study of docetaxel/TS-1 with radiation for esophageal cancer patients--step 1].
The therapy 5-FU and CDDP with radiation is thought to be the standard therapy for esophageal cancer patients by now. However, the therapy is associated with a comparatively high incidence of gastrointestinal disorders and requires hospitalization. We have proposed a new regimen of Docetaxel and TS-1 with radiation for maintaining of QOL and improving outcome. Step 1 of the clinical phase I/ II study was conducted for 10 cases from May 2004 to March 2006. Treatment could be accomplished in all cases, and no treatment-related deaths or adverse events of grade 4 were observed in any case. As for hematotoxicity, one case had leucopenia of grade 3 and neutropenia of grade 2. As for non-hematotoxic adverse events, anorexia of grade 3 was recognized in one case of level 3. The response rate evaluated by RECIST was 66% (CR in 2 cases, PR in 4 cases), and the rate based on the Guide Lines for the Clinical and Pathologic Studies on Carcinoma of Esophagus by the Japanese Society for Esophageal Cancer was 70% (CR in 3 cases, PR in 4 cases). We assumed that the recommended dosage of TXT was 30 mg/m(2) and that of TS-1 was 60 mg/m(2) with radiotherapy of 60 Gy. This combination therapy may be recommended because of fewer adverse events and a higher responsive rate than the standard therapies. We intend to continue this study to step 2 and 3, and to reveal the response rate and adverse events for more esophageal cancer patients.

Effect and safety of anlotinib combined with S-1 for recurrent or metastatic esophageal cancer patients who refused or were intolerant to intravenous chemotherapy.
This study aimed to evaluate the effect and safety of anlotinib combined with S-1 in the treatment of recurrent or metastatic esophageal cancer patients who refused or were intolerant to intravenous chemotherapy.This study retrospectively reviewed 22 recurrent or metastatic esophageal cancer patients who refused or were intolerant to intravenous chemotherapy between June 1, 2018 and February 28, 2019. All patients did not previously receive anlotinib or S-1.Of 22 patients, 20 patients had squamous cell cancer. Seventeen patients received at least 2 cycles of anlotinib plus S-1. The objective response rate (ORR) was 35.3%, and the disease control rate (DCR) was 82.4%. The median progression-free survival (PFS) was 3.5 months, and median overall survival (OS) was 5.2 months. In the first-line treatment subgroup, the ORR was 50%, the DCR was 80%, the median PFS was 4.5 months, and the median OS was 5.8 months. In the second-line and above treatment subgroup, the ORR was 14.3%, the DCR was 85.7%, the median PFS was 3.0 months, and the median OS was 3.7 months. The main adverse events (AEs) of anlotinib combined with S-1 were fatigue (58.8%), hypertension (47.1%), hemoptysis (29.4%), anemia (29.4%), nausea (23.5%), liver function damage (23.5%), albuminuria (17.6%), abdominal pain (17.6%), leukopenia (17.6%), neutropenia (11.8%), fever (11.8%), and hand-foot syndrome (11.8%). Grade 3 AEs included nausea (5.9%) and hypertension (5.9%), and no grade 4 or more AEs were reported.Anlotinib combined with S-1 achieved promising disease control and satisfactory survival with tolerable safety in recurrent metastatic esophageal cancer who refused or were intolerant to intravenous chemotherapy.

Oral maintenance therapy using apatinib combined with S-1/capecitabine for esophageal squamous cell carcinoma with residual disease after definitive chemoradiotherapy.
A substantial number of patients with esophageal squamous cell carcinoma (ESCC) do not achieve complete remission after definitive concurrent chemoradiotherapy (dCRT). We performed this retrospective study to evaluate the efficacy and safety of apatinib combined with S-1/capecitabine as the oral maintenance therapy for these patients.. Thirty-nine ESCC patients with residual disease after dCRT were included. Patients were treated with apatinib combined with S-1 /capecitabine after dCRT. Efficacy, toxicity, and survival were analyzed.. Of the 39 patients, 5 (12.8%) achieved a partial response and 29 (74.4%) achieved stable disease, yielding a disease control rate of 87.2%. The median progression-free survival (PFS) and overall survival (OS) were 27.5 (95%CI: 14.9 - 40.1) and 38.1 (95%CI: 31.3 - 44.8) months. Most frequent adverse events were of grade 1 to 2. Multivariate analysis revealed the occurrence of any adverse events (HR = 0.274, 95%[CI] = 0.119 - 0.630) correlated to better PFS and occurrence of proteinuria (HR = 0.108, 95%[CI] = 0.025 - 0.456) predicted better OS.. The oral combination therapy consisting of apatinib and S-1/capecitabine showed a tolerable toxicity profile and achieved satisfactory disease control in ESCC patients with residual disease after dCRT.

[Successful Administration of Alternate-Day, Low-Dose S-1 in a Patient with Recurrent Esophageal Cancer with a Poor Compliance Profile].
A 79-year-old woman had recurrence in the mediastinal lymph node 6 months after curative resection of advanced esophageal cancer(pStage Ⅲ). After radiation therapy and 12 courses of chemotherapy with docetaxel, new recurrent tumors progressed in the mediastinum and apical region of the left lung, and her performance status(PS)deteriorated to grade 3. Alternate-day, low-dose S-1 chemotherapy was started at a dose of 60mg/day. Tumors decreased in size within 6 months, and her PS improved from grade 3 to 0. She had been treated for 33 months without severe adverse events until disease progression. So far, we have experienced in clinical practices that the alternate-day S-1 administration was tolerable for patients who were unfit for the standard daily administration. Alternate-day, low-dose S-1 administration may be a sustainable and effective option in S-1 chemotherapy in patients with recurrent esophageal cancer with impaired PS.

S-1 in Patients with Advanced Esophagogastric Adenocarcinoma: Results from the Safety Compliance Observatory on Oral fluoroPyrimidines (SCOOP) Study.
S-1-based regimens have been shown to be as effective as other fluoropyrimidine-based regimens with a better safety profile in patients with advanced esophagogastric adenocarcinoma. However, real-world data on S-1 in European patients with advanced esophagogastric adenocarcinoma are lacking. The Safety Compliance Observatory on Oral fluoroPyrimidines (SCOOP) study evaluated safety and relative dose intensities for patients treated with S-1-based regimens for advanced esophagogastric adenocarcinoma as part of daily practice.. Overall, data for 125 patients with advanced esophagogastric adenocarcinoma were collected at 21 centers in five countries in Europe. Demographics, treatment, and adverse-event data were recorded over a planned treatment of six cycles.. Most patients (87%) received combination treatment of S-1 plus a platinum compound. Adverse events related to S-1 treatment were mostly grade 1 or 2 while reported grade 3-4 serious adverse events related to S-1 occurred in 12 patients and were most often grade 3 neutropenia (n = 4, 3.2%) or diarrhea (n = 5, 4%). The most common adverse events of any grade that were attributable to S-1 treatment included neutropenia, anemia, thrombocytopenia, diarrhea, nausea, vomiting, and fatigue. No patients experienced mucositis, dehydration, or febrile neutropenia, whereas 2% (3/125) of patients experienced hand-foot syndrome.. The overall relative dose intensity was 70%. In a real-world setting, patients with advanced esophagogastric adenocarcinoma tolerated S-1 treatment well with high compliance rates. The SCOOP study provides valuable information on S-1 relative dose intensity that can be used for treatment decision making.

S-1 Monotherapy After Failure of Platinum Plus 5-Fluorouracil Chemotherapy in Recurrent or Metastatic Esophageal Carcinoma.
Platinum plus 5-fluorouracil (FP) is a first-line regimen of palliative chemotherapy for recurrent or metastatic esophageal squamous cell carcinoma (RM-ESCC). In this retrospective study, we evaluated the efficacy and safety of S-1 monotherapy as a salvage line treatment for RM-ESCC, focusing on the reasons for discontinuation of prior FP.. The subjects of this study had RM-ESCC and received S-1 after failure of FP.. Eleven patients were enrolled. Nine patients were refractory and two were intolerant to prior FP. The median progression-free survival and overall survival time were 3.0 and 11.7 months, respectively. Overall response rate was 22.2% and disease control rate of the 11 patients was 36.4%. Median relative dose intensity of 5-FU was 100% (range=85-100%).. S-1 efficacy in RM-ESCC when given after FP was modest. Favorable OS may be attributed to good local control rather than to the efficacy of S-1 monotherapy.

[A Case of Advanced Esophagogastric Junction Cancer Responding to S-1 Neoadjuvant Chemotherapy].
A 56-year-old man was diagnosed with advanced adenocarcinoma of the esophagogastric junction. He received 1 course of neoadjuvant chemotherapy with S-1. After neoadjuvant chemotherapy, the primary tumor showed a remarkable decrease in size. Subtotalesophagectomy, D2 lymph node dissection, and reconstruction with a gastric tube through the posterior mediastinal route were performed. Pathological examination showed that most of the cancer cells had been destroyed, with a part where adenocarcinoma mucosa was seen. We successfully treated a case of advanced adenocarcinoma of the esophagogastric junction, with neoadjuvant S-1 chemotherapy and surgicalresection.

[Radical Thoracoscopic Esophagectomy for Elderly Patients with Advanced Esophageal Cancer].
We report a case of an elderly patient with advanced esophageal cancer who underwent multidisciplinary treatment. An 86-year-old male consulted our hospital with complaints of pharynx discomfort and difficulty in swallowing. He was preoperatively diagnosed with esophageal cancer, T3N2M0, Stage III . We performed 2 courses of cisplatin plus 5-FU therapy as neoadjuvant chemotherapy. The primary tumor and metastatic lymph nodes reduced in size, and thoracoscopic esophagectomy in the prone position was performed. Pathological findings were esophageal cancer, pT3-Ad, INF b, ly2, v1, IM0, pPM0, pDM0, pRM1, pN3, pStage III . As the radical margin was positive, chemoradiotherapy was performed. We continued postoperative chemotherapy for approximately 1 year, and the patient has survived without relapse for 4 years from esophagectomy. Even in patients over 80 years old, long-term prognosis can be expected by performing radical surgery and chemoradiotherapy.

A retrospective clinical study of comparing paclitaxel plus S-1 versus paclitaxel plus cisplatin as the first-line treatment for patients with advanced esophageal squamous cell carcinoma.
In advanced esophageal squamous cell carcinoma (ESCC), paclitaxel plus cisplatin are considered as active and tolerable. The current clinical study was conducted to retrospectively compare the efficacy and safety of first-line paclitaxel/S-1(PS) and paclitaxel/cisplatin(TP) regimens in advanced ESCC.. The overall response rate of PS was slightly, but not significantly, higher (25 patients, 46%) than that of TP (23 patients, 39%, P = 0.432). Median overall survival (OS) was similar for PS and TP (11.5 months vs. 10.4 months, p = 0.37). However PS had longer median progression-free survival than TP (PFS: 5.5 months vs5.0months, p = 0.04). When compared with PS, more grade 3 or 4 adverse events were recorded for TP, including leukopenia, neutropenia, anemia, anorexia and vomiting (P < 0.05). No treatment-related deaths were recorded in either group.. Between 2008 and 2014, all patients diagnosed with advanced ESCC and treated with paclitaxel/S-1 or paclitaxel/cisplatin at Cancer Hospital Affiliated to Zhengzhou University were analyzed retrospectively. One hundred and thirteen patients were included in this study. Disease control rates and progression-free survival (PFS) and overall survival (OS) were recorded. Survival analysis was calculated by using Kaplan-Meier method.. The PS option improves PFS and its OS is similar to TP. Moreover, the PS regimen is an effective and safe first-line treatment for ESCC with less hematological and non-hematological toxicity.

Prognostic impact of HER2, EGFR, and c-MET status on overall survival of advanced gastric cancer patients.
This study was conducted to investigate whether human epidermal growth factor receptor 2 (HER2) status, epidermal growth factor receptor (EGFR) status, and c-MET status are independent prognostic factors for advanced gastric cancer patients who received standard chemotherapy.. Unresectable or recurrent gastric or gastroesophageal junction cancer patients with histologically confirmed adenocarcinoma treated with S-1 plus cisplatin as first-line chemotherapy were eligible. Formalin-fixed paraffin-embedded tumor samples were examined for HER2, EGFR, and c-MET status using immunohistochemistry (IHC). Additionally, gene amplification was examined using fluorescent in situ hybridization (FISH) for HER2. Positivity was defined as an IHC score of 3+ or an IHC score of 2+/FISH positive for HER2, and an IHC score of 2+ or 3+ for both EGFR and c-MET.. Of the 293 patients from nine institutions, 43 (15%) were HER2 positive, 79 (27%) were EGFR positive, and 120 (41%) were c-MET positive. Ten patients (3%) showed positive co-expression of HER2, EGFR, and c-MET. After a median follow-up time of 58.4 months with 280 deaths, there was no significant difference in overall survival (OS) in terms of HER2 and EGFR status. However, there was a significant difference in OS between c-MET-positive and c-MET-negative patients [median, 11.9 months vs 14.2 months; hazard ratio, 1.31 (95% confidence interval, 1.03-1.67); log-rank P = 0.024]. Multivariate analysis also showed that c-MET positivity was still a prognostic factor for OS [hazard ratio, 1.30 (95% confidence interval, 1.02-1.67); P = 0.037].. The study suggested that c-MET-positive status had poor prognostic value. These data could be used as the basis for future clinical trials for targeting agents for advanced gastric cancer patients.

Efficacy and feasibility of ambulatory treatment-based monthly nedaplatin plus S-1 in definitive or salvage concurrent chemoradiotherapy for early, advanced, and relapsed esophageal cancer.
Standard chemoradiotherapy (CRT) using cisplatin (CDDP) and 5-fluorouracil (5-FU) is an optional treatment for patients with stage II-III esophageal cancer. However, there are some demerits in this regimen because CDDP administration requires a large transfusion volume and 5-FU must be continuously infused over 24 h. Therefore, hospitalization is unavoidable. We collected retrospectively the data of definitive CRT with nedaplatin and S-1 as carried out in our institution.. Patients with early and advanced esophageal cancer and relapsed esophageal cancer after radical surgery were included. Nedaplatin 80 mg/m(2) was given on days 1 and 29, and S-1 80 mg/m(2) on days 1-14 and 29-42. No prophylactic treatment with granulocyte colony stimulating factor was administered. Patients received two courses of concurrent radiotherapy of more than 50 Gy with or without two additional courses as adjuvant therapy every 4 weeks.. Between August 2011 and June 2015, 89 patients (age range, 44-86 years; K-PS 90-100, 81 %; squamous cell carcinoma histology, 97 %; definitive/salvage CRT, 75/25 %) were collected. Twenty-one (24 %) patients completed four cycles, and 94 % received two or more cycles. Grade 4 leukopenia, thrombocytopenia, and anemia occurred in 12, 7, and 10 % of the patients, respectively. Five patients developed febrile neutropenia. Grade 3 non-hematological toxicity included infection in 12 %, mucositis/esophagitis in 3 %, kidney in 3 %, and fatigue in 3 %. Sixty-four patients (72 %) received the prescribed full dose and full cycles of chemotherapy. A complete response was achieved in 76 patients (85 %). The 3-year overall survival rate was 54.4 % in definitive CRT and 39.8 % in salvage CRT, respectively. Sixty-two subjects (70 %) received treatment as outpatients.. Nedaplatin and S-1 in combination with radiotherapy is feasible, and toxicity is tolerable. This treatment method has the potential to shorten hospitalization without impairing the efficacy of CRT.

Comparison of Definitive Chemoradiotherapy in Locally Advanced Esophageal Squamous Cell Carcinoma.
This retrospective study was designed to estimate the efficacy and toxicity of definitive radiotherapy with concurrent or sequential docetaxel/S-1 for patients with locally advanced esophageal squamous cell carcinoma (ESCC).. Of the 62 eligible patients enrolled in this study during January 1, 2010 to December 31, 2014 from Qilu Hospital, Shandong University, Shandong Province, 39 patients received 3 cycles of docetaxel/S-1 during and after radiotherapy (concurrent chemoradiotherapy, CCRT), and 23 patients had radiotherapy followed by 3 cycles of docetaxel and S-1 (sequential chemoradiotherapy, SCRT).. The CR of CCRT and SCRT groups were 48.72 and 21.74 %, respectively (p = 0.035). The median progress-free survival (PFS) of CCRT group (23.5 months) was significantly higher than SCRT group (11.7 months; p = 0.004). The median overall survival (OS) of CCRT group (33.5 months) also was significantly higher than SCRT group (24.0 months; p = 0.004). At 2 years, in this patient population, the rate of PFS of CCRT group was (44.2 ± 8.2 %), significantly higher than SCRT group (11.9 ± 9.6 %; p = 0.002). The 2-year OS rate of CCRT (68.6 ± 7.5 %) was significantly higher than SCRT group as well (42.0 ± 14.0 %; p = 0.002). The incidence of adverse events was higher in CCRT than SCRT group. No grade 4 or grade 5 adverse events occurred in our study.. Definitive radiotherapy with concurrent or sequential docetaxel and S-1 for inoperable locally advanced ESCC was very well tolerated and remarkably active. In both CCRT and SCRT groups, acute toxicities were manageable. This regimen holds promises for treatment of esophageal carcinoma and warrants further investigation.

[A Case of Synchronous Esophageal and Gastric Cancer Successfully Treated Using Multimodal Therapy].
We report a case of advanced esophageal and gastric cancer that was successfully treated via multimodal therapy. A 65- year-old man with hoarseness was referred to our hospital. He was diagnosed with clinical T4aN2M0, Stage IV esophageal squamous cell carcinoma and clinical T3N1M0, Stage II B gastric adenocarcinoma. He was treated with 3 courses of chemotherapy, administered over 4weeks, with S-1(80mg/m / / 2: day 1-14), cisplatin(60mg/m2: day 1), and docetaxel(40mg/m2: day 1). Computed tomography(CT)revealed shrinkage of the primary esophageal tumor, gastric tumor, and lymph node metastases. Next, we selected definitive radiation chemotherapy(CRT), because lymph node metastases remained around the bilateral recurrent laryngeal nerves. After CRT with a total 60 Gy plus administration of 5-fluorouracil and cisplatin, CT showed that the primary esophageal tumor and lymph node metastases had disappeared. Then, distal gastrectomy was performed for the remaining gastric cancer, as part of the multimodal therapy. After gastrectomy, no systemic chemotherapy was performed. At a follow-up examination 5 years and 6 months after the start of chemotherapy, the patient is alive without recurrence.

[A Case of Successful Multidisciplinary Therapy for Advanced Esophagogastric Junction Cancer with Multiple Lymph Node Metastase].
A 64-year-old man reporting dysphagia was examined. Upper gastrointestinal endoscopy showed a type 3 cancer at the esophagogastric junction. Enhanced CT scan showed several swollen mediastinal and abdominal lymph nodes. We diagnosed the patient with advanced adenocarcinoma of the esophagogastric junction with multiple lymph node metastases(Siewert type II , cT3N2M1[LYM], Stage IV ). After 5 courses of chemotherapy(S-1 plus cisplatin), a significant reduction was observed in the size of the tumor and lymph nodes. Therefore, we performed conversion surgery. The patient underwent esophagectomy and mediastinal lymph node dissection using a right thoracotomy approach. He has survived without recurrence in the 10 months since this radical surgery.

[A Case of Carcinosarcoma of the Esophagus Treated with Chemoradiotherapy].
Carcinosarcoma of the esophagus is a rare malignant neoplasm. We report a case of an 87-year-old man treated with chemoradiotherapy. The main presenting complaint was hiccups. Histological analysis of a biopsy from the tumor demonstrated a carcinosarcoma. The clinical diagnosis was T2N0M0, cStageⅡ. In consideration of his advanced age, a past history of cerebral infarction, high blood pressure, aortic valve sclerosis, and chronic renal failure (Cr 1.5-1.8 mg/dL), chemoradiotherapy consisting of TS-1 40 mg/day with radiotherapy of 66 Gy was administered to the patient. The carcinosarcoma decreased in size on endoscopic examination in response to the chemoradiotherapy. Surgery with extended lymphadenectomy for esophageal carcinosarcoma is the standard treatment, but chemotherapy may be a good choice for local control for patients who cannot undergo surgical resection.

[Effectiveness of chemoradiotherapy for a patient with local recurrence of advanced gastric cancer followed by curable gastrectomy].
We report here the effectiveness of chemoradiotherapy for a patient with local recurrence followed by curable gastrectomy. A 57-year-old man presented with a history of total gastrectomy with distal pancreatectomy and splenectomy, D2 lymphadenectomy, and Roux-en-Y reconstruction for advanced gastric cancer arising from the cardia. Esophageal intramural metastasis and lymph node metastasis around the right recurrent nerve were detected by chest-abdominal computed tomography and gastrointestinal endoscopy 27 months after the initial gastrectomy. Stable disease was achieved following 7 courses of chemotherapy using S-1 plus CDDP. Concurrent chemoradiotherapy including administration of S-1 and radiation of total 50 Gy (2 Gy/25 Fr) was selected for local tumor control. The patient was not able to eat solid food because of esophageal stenosis from regrowth of intramural metastasis of the esophagus 60 months after the chemotherapy. A WallFlex™ Duodenal Stent was placed to improve the dysphagia 67 months after chemotherapy. The patient died from recurrence of gastric cancer 69 months after completion of the initial chemotherapy and 2 months after the stent insertion.

[A case of AFP-producing esophagogastric junction cancer with liver metastases with a good response to chemotherapy].
A 62-year-old man was diagnosed with esophagogastric junction cancer following esophagogastroduodenoscopy in response to hematemesis. Although liver metastasis was detected during surgery, a total gastrectomy and lower esophagus resection for local control was performed. Alpha-fetoprotein(AFP)-producing tumor with hepatoid adenocarcinoma was diagnosed on the basis of the pathological examination. Serum AFP levels remained high postoperatively and multiple liver metastases were detected on computed tomography imaging. After 6 courses of chemotherapy with S-1 and cisplatin (CDDP), a significant reduction in the size of the liver metastases and a decrease of serum AFP levels were achieved. Postoperative 2-year tumor control using S-1 single agent chemotherapy was obtained. AFP-producing esophagogastric junction cancer has a poor prognosis. This case raises the possibility that long-term survival can be obtained by combining surgery for local control with systemic chemotherapy.

S-1 monotherapy as second- or third-line chemotherapy for unresectable and recurrent esophageal squamous cell carcinoma.
S-1 is widely used for various cancers. It may be useful for esophageal squamous cell carcinoma (ESCC); however, there are insufficient data. The purpose is to provide results of an analysis of S-1 monotherapy for unresectable and recurrent ESCC.. Twenty patients with histologically proven ESCC who were previously treated with other chemo(radio)therapies were treated with S-1 alone as second- or third-line chemotherapy.. A complete response (CR) was observed in 1 case (5%). A partial response (PR), stable disease (SD), and progressive disease (PD) were seen in 4 (20.0%), 7 (35.0%), and 8 (40.0%) cases, respectively. Two cases (10%) of anemia, 1 case (5%) of leukopenia, 3 cases (15%) of fatigue, and 3 cases (15%) of diarrhea were observed as grade 3 toxicity; however, there were no cases of grade 4 toxicity. The 1-year progression-free survival (PFS) rate was 10.0%, and the median PFS was 100 days. The 1-year overall survival (OS) was 30.5%, and the median OS was 330 days. The 1-year PFS rate in CR/PR/SD and PD was 16.7 and 0%, and the median survival time was 120 and 40 days.. S-1 is a promising new drug which can be used as a second- or third-line chemotherapy for ESCC.

[A case of esophageal cancer with a funnel chest].
Esophageal cancer is a disease that is difficult to manage before and after surgery and is associated with a high in-hospital mortality rate despite there being reports of improved outcomes after multidisciplinary treatment. Meanwhile, although funnel chest is generally a subclinical condition, patients with this deformity may sometimes present with cardiac failure and chest pain. We report a case of advanced esophageal cancer with a funnel chest deformity that was very difficult to reconstruct after thoracoscopy-assisted resection.

[Docetaxel plus S-1 as a second-line chemotherapy for metastasis or recurrence of esophageal cancer].
Although chemotherapy consisting of cisplatin and 5-fluorouracil(CF)has been a standard regimen for esophageal cancer, it might be difficult to use continuously. This study evaluated the response and safety of docetaxel plus S-1 used as a second line therapy. We reviewed 21 patients(postoperatively, 11; after definitive chemoradiotherapy, 8; after chemotherapy, 2) who received chemotherapy between 2006 and 2010. Metastatic or recurrent disease was detected in the organs(n=8), lymph nodes(n=8), main tumors(n=3), mediastinum(n=1), and pleura(n=1). Docetaxel 30mg/m2 was infused every 2 weeks, and S-1 80mg/m2 was taken for 2 weeks, then with 2 weeks rest until progression. Almost all of the patients received docetaxel in the outpatient chemotherapy room. The median number of treatment cycles was 3, ranging from 1-12. Among the 14 patients with a therapeutic response, three(21%)achieved PR, 8 showed SD, and 3 had PD. Toxicity which included grade 3/4 was neutropenia in 6 patients, and anemia in one patient. After a follow-up of over one year, the median overall survival was 10 months, and the one-year survival rate was 38%. Docetaxel plus S-1 might be a feasible regimen as a second-line chemotherapy for metastasis or recurrence of esophageal cancer.

A pilot trial of S-1 plus irinotecan chemotherapy for esophageal adenocarcinoma.
This study investigated the clinical efficacy and toxicity of the combination chemotherapy using S-1 plus irinotecan for esophageal adenocarcinoma.. This study included 10 patients with histologically confirmed adenocarcinoma of the esophagus or esophagogastric junction between April 2005 and August 2011. S-1 was administered orally at a dose of 80 mg/m²/day from day 1 to 14 and irinotecan was given intravenously on day 1 and 8 at a dose of 80 mg/m².. A total of 65 cycles were administered and the response rate was 62.5%. The 50% progression-free survival period and the 50% overall survival period for all of the patients was 8.4 months and 19.1 months, respectively and 5.9 months and 16.3 months for the 8 patients with unresectable or recurrent tumors, respectively. The 2 patients that received adjuvant chemotherapy demonstrated a prophylactic effect for the post-operative recurrence. On the other hand, this therapy showed no severe non-hematological toxicity and only 20% experienced grade 3 neutropenia. As a result, the treatment regimen could generally be performed in an outpatient basis.. The combination chemotherapy using S-1 and irinotecan showed tolerable clinical efficacy in terms of the response rate, survival and toxicity for esophageal adenocarcinoma.

A complete response to S-1 plus cis-diamminedichloroplatinum in advanced-stage esophageal and gastric adenocarcinoma: a case report.
Complete remission from advanced-stage synchronous double primary (SDP) esophageal and gastric adenocarcinoma by chemotherapy alone is rare. We report a case of advanced-stage SDP esophageal and gastric adenocarcinoma in which a complete response to treatment was obtained with S-1 and cis-diamminedichloroplatinum (CDDP).. The patient was a 74-year-old man referred to our hospital complaining of dysphagia. Gastrointestinal endoscopy was performed and advanced-stage SDP esophageal and gastric adenocarcinoma diagnosed. Computed tomography revealed multiple regional lymph node metastases in the mediastinum. Neoadjuvant chemotherapy with S-1 and CDDP for advanced esophageal and gastric cancer was planned. An endoscopy following two courses of chemotherapy revealed that the esophageal cancer had been replaced with a normal mucosal lesion and the gastric tumor with a scar lesion; the results of biopsies of both were negative for cancer. Computed tomography revealed that the multiple lymph node metastases had disappeared. We diagnosed a complete response to S-1 and CDDP in advanced-stage SDP esophageal and gastric cancer. The patient is still alive with no signs of recurrence 22 months after the disappearance of the original tumor and metastatic lesions without surgical treatment.. These results suggest that complete remission from advanced-stage esophageal and gastric cancer can be obtained with chemotherapy with S-1 plus CDDP.

Evaluation of 5-FU plasma concentration by 13C breath test in patients treated with oral 5-FU analogs.
The objective of this study was to investigate the influence of digestive gastrointestinal absorption function on the pharmacokinetics of the orally-administered anticancer drug, Tegafur-gimestat-otastat potassium (TS-1), by measuring the plasma 5-fluorouracil (5-FU) concentration using stable isotope breath tests.. Twenty-nine patients with progressive/recurrent digestive organ cancer were enrolled for this pharmacokinetic study, and blood samples were obtained from each patient. The area under-the-time-concentration curve between 0 and 480 min (AUC0-480 min), time-of-drug concentration peak (T(max)), maximum drug concentration (C(max)) and the half-life period (t(1/2)) of 5-FU were investigated. Simultaneously, a continuous (13)C-acetate breath test was performed for each patient. The parameters measured with the breath test were the area under the (13)CO(2) excretion rate curve between 0-4 h (AUC(0-4h)), peak (13)CO(2) value and elimination rate constant (K(el)) value.. The AUC(0-8h) and C(max) of 5-FU were significantly correlated with K(el) (p=0.012 and p=0.024, respectively), and the 5-FU C(max) value was significantly correlated with the peak value of (13)CO(2) (p=0.037). Multivariate regression analysis also found the C(max) of 5-FU to be associated with K(el) (p=0.0118). The C(max) and AUC(0-8h) of 5-FU were also significantly correlated (p<0.0001).. The results of this study suggest that gastrointestinal absorption is closely-related to plasma 5-FU concentration after oral administration of TS-1.

[A case of advanced gastric cancer with esophageal severe dysplasia resected after neoadjuvant S-1+cisplatin therapy].
A 72-year-old man was admitted to our hospital complaining of upper abdominal pain and back pain. Advanced gastric cancer was found at the fundus of the stomach, and severe dysplasia was found at the lower esophagus. We proceeded with neoadjuvant chemotherapy (S-1+CDDP) because the lymph nodes in the lesser curvature of the stomach were metastasized and invasion of the pancreas and some vessels was suspected by computed tomography. The tumor size was reduced remarkably, the esophageal dysplasia disappeared after preoperative chemotherapy, and we were able to perform total gastrectomy.

A case of complete response to S-1 plus CDDP in early-stage mucosal esophageal cancer.
We report a case of early-stage mucosal esophageal cancer, showing a complete response to S-1 and cis-diamminedichloplatinum (CDDP). The patient was a 67-year-old man with synchronous double primary early-stage mucosal esophageal and advanced gastric cancer. We planned neoadjuvant chemotherapy with S-1 and CDDP for the advanced gastric cancer and endoscopic mucosal resection for the early-stage esophageal cancer. After the first course of chemotherapy, the endoscopy revealed that the esophageal cancer had become a normal mucosal lesion, and the biopsy was negative for cancer. We diagnosed a complete response to S-1 and CDDP in early-stage esophageal cancer. After two courses of chemotherapy, distal gastrectomy was performed. The patient is still alive with no sign of recurrence at 16 months after the disappearance of the original tumor. These results suggest that chemotherapy with S-1 plus CDDP may be effective in early-stage esophageal cancer.

[A case of advanced adenocarcinoma of esophagogastric junction with severe esophageal invasion effectively treated by chemoradiotherapy using paclitaxel and cisplatin, and S-1 after chemoradiotherapy].
The patient was a 66-year-old male with adenocarcinoma of the esophagogastric junction and severe esophageal invasion, which was diagnosed as cType 3, cT4a (SE) cN3cM1 (LYM), cStage IV(histopathology: por 1). We tried concurrent chemoradiotherapy consisting of PTX 60 mg/m(2) and CDDP 25 mg/m(2), respectively (once a week), and a total of 45 Gy of radiotherapy treatment. Then, for effective continuation, chemotherapy using S-1 was performed as second-line therapy. A complete response was achieved and continued for more than 2 years after initial chemoradiotherapy; his complaints abated and his quality of life improved. Although gastro-intestinal symptoms and bone marrow suppression were observed as adverse effects, they were within a tolerable range and did not interfere with the concurrent chemoradiotherapy. This regimen appears to be feasible and effective for advanced gastric carcinoma refractory to other regimens.

[A case of adenocarcinoma of the esophagogastric junction successfully treated with chemoradiation therapy].
The patient was an 80-year-old female with chief complaint of anemia. She was diagnosed as a type 3 gastric cancer (por/tub2) of the esophagogastric junction by gastrointestinal endoscopy in November 2010. CT scan revealed no distant metastasis and we diagnosed as c-stage II B (T4aN0M0). However, severe COPD was detected by the respiratory function test. Considering her age and respiratory function, we decided that total gastrectomy under general anesthesia was difficult. She was treated with radiation( 50.4 Gy/28 Fr) and the combination chemotherapy of S-1( 80 mg/m², day 1-21) plus low-dose CDDP (6 mg/m², day 1-5, 8-12, 15-19) during her hospitalization, and treated with S-1 mono-therapy as an outpatient. The tumor was reduced and the hemorrhage was not seen though the response was SD. Moreover, she did not experience any adverse event of grade 3 or more. The chemoradiation therapy appears to be effective for patients of adenocarcinoma of the esophagogastric junction.

[A case of residual metastatic lymph node lesion following definitive chemoradiotherapy for T4 esophageal cancer, successfully treated by outpatient clinic-based sequential chemotherapy with docetaxel followed by S-1].
Patients with T4 esophageal cancer generally have poor prognosis. Of these patients, prognosis of non-responder to chemoradiothrapy (CRT) is extremely poor. We report a case of residual lymph node metastasis following definitive CRT, which showed a good response to outpatient clinic-based chemotherapy consisting of docetaxel (DOC) followed by S-1 in a patient with T4 esophageal cancer. The patient was a 65-year-old man with the diagnosis of squamous cell carcinoma of the middle thoracic esophagus with the 5 cm size lymph node metastasis with tracheal invasion along right recurrent laryngeal nerve [T4 (106recR-rt subclavian A) N2M0, Stage IVa]. He underwent induction chemotherapy with two courses of FP followed by one course of DCF. As a result, primary tumor was judged as complete response on endoscopy, and the lymph node lesion was judged as partial response, but unresectable on CT. Then, he underwent definitive CRT (FP+60 Gy). Following CRT, although the lymph node lesion was judged as non-CR on CT, a significant decrease of FDG uptake (PET-CR) was observed on PET-CT. Five months later, a recurrence of the lymph node lesion was observed on PET-CT. Then, he underwent outpatient clinic-based chemotherapy with DOC( 60 mg/m², triweekly) followed by S-1( 80 mg/ body/day, 6 weeks/course, administration for 4 weeks with 2 weeks cessation). DOC was administered for 8 months, and was converted to S-1 because of the regrowth of the lesion on PET-CT. After 3 months following initiation of S-1, a remarkable decrease of the lesion was observed on PET-CT. During outpatient clinic observation, the residual lymph node lesion after definitive CRT was well controlled over 1 year, and no new metastatic lesions were observed at other sites. Sequential chemotherapy with DOC followed by S-1 may be effective in controlling progression of resistant tumor against prior CRT.

[Complete response in a case of advanced unresectable esophageal cancer treated by chemoradiation therapy and S-1+CDDP chemotherapy].
We report a 37-year-old woman who complained of chest discomfort as of August 2004, and was found to have advanced esophageal cancer in the upper thoracic area in December 2004.S he was diagnosed as Stage IVa (T4N1M0) because chest computed tomography (CT) indicated trachea invasion and lymph node metastasis. We diagnosed it to be a case of unresectable esophageal cancer, and she underwent chemoradiation therapy. CT showed regression of the main tumor and metastatic lymph nodes when the CRT course was completed. The main tumor disappeared macroscopically. We again considered an operation, but the CRT was so effective that the patient wished to continue CRT and underwent three courses. Endoscopy showed disappearance of the main tumor and Lugol's solution. Following this, 10 courses of the treatment with CDDP alone (CDDP 10 mg/weekly) were continued until the appearance of renal dysfunction. S-1 (100 mg/body/day)was started in September 2005. The treatment is currently ongoing, and no recurrence or metastases had occurred as of March 2009.

A complete response in small cell carcinoma of the esophagus treated by s-1/cisplatin combined chemotherapy and radiotherapy.
Small cell carcinoma of the esophagus (SmCCE) is a rare disease which is considered to be more malignant than the most common types of esophageal cancer. The optimal treatment strategy for this disease still remains controversial. A 69-year-old male was diagnosed to have SmCCE (stage IIIA, T3N1M0). Due to the patient's poor general condition, chemo-radiotherapy consisting of S-1/cisplatin therapy and a total of 60 Gy of radiotherapy was performed. After the treatment, the main lesion completely disappeared while some ulceration remained. A histological examination revealed no viable cancer cells in biopsy specimens obtained by endoscopy. Computed tomographic examinations showed a decreased wall thickness of the esophagus and an improvement in the swelling of the lymph nodes. S-1 monotherapy was administered following the main chemoradiation therapy, and it was performed for a total of 20 courses. The patient has been doing well without recurrence for over 3 years. We judged the effect to be a complete response. This combination chemo-radiotherapy with S-1 and cisplatin may therefore be one of the effective treatments against SmCCE.

[A case report of bi-weekly docetaxel and S-1 combination chemotherapy for gastric cancer with multiple liver metastases and esophageal invasion].
A 61-year-old man with the chief complaint of pressure with swallowing was referred to our hospital with type 3 cardiac gastric cancer. Gastrofiberscope showed type 3 cardiac cancer with esophageal invasion. On the abdominal computed tomography, there was evidence of lymph node swelling in the lesser curvature and multiple liver metastases. Blood tumor markers were elevated: CEA 200 ng/mL, CA19-9 2,490 U/mL. He was diagnosed as unresectable advanced gastric cancer UE-circ, type-3, c-T3N2H1P0M1, Stage IV. A biopsy revealed adenocarcinoma (tub2-por1). We started bi-weekly docetaxel and S-1 combination chemotherapy(DOC 40 mg/m2 day 1, 14, S-180 mg/m2 day 1-7, 14-21). After completion of the first course of this combination therapy, his feeling of pressure was relieved and CT showed reduction of multiple liver lesions and lymph node metastases, indicating partial response. No regrowth was seen for 7 courses of the therapy. Regarding toxicity, grade 2 nausea and grade 1 nail pain were observed. After 7 courses, because of serum CEA elevation, bi-weekly CPT-11/CDDP therapy (CPT-11 60 mg/m2, CDDP 30 mg/m2) was administered followed by weekly PTX therapy (65 mg/m2 day 1, 7, 14; total of 4 weeks). To date, 17 months after administration of chemotherapy, he has been treated on an outpatient basis. Biweekly DOC/S-1 therapy can be novel antitumor therapy which can be conducted safely in an outpatient setting for advanced gastric cancer.

[Effects of concurrent S-1, nedaplatin/radiation therapy for 5 cases of head and neck cancer with esophageal carcinoma].
It is not rare to observe multiple cancers in cases of head and neck carcinoma. Such cancers are important factors for deciding the therapeutic strategy. Complications of esophageal cancer are particularly frequent in cases of hypopharyngeal cancer in comparison to other head and neck tumors. At our department, for organ and functional preservation, and radical cure, we have used simultaneous therapy instead of separate therapy for head and neck tumors and esophageal cancer. We have been implementing concurrent S-1, nedaplatin/radiation therapy (hereinafter called SN therapy) for cases of advanced cancer of the head and neck, and we applied the same therapy for cases of head and neck carcinoma with esophageal cancer. The subjects comprised 5 cases of head and neck tumors complicated by esophageal cancer for which therapy was conducted at our department between April 2005 and March 2009. The histologic type was squamous cell carcinoma in all of the cases. There were 2 cases of laryngeal cancer (T3N2cM0, T3N0M0) and 3 cases of hypopharyngeal cancer (T3N2cM0, T4N2cM0, T3N2bM0). As a result, 3 out of the 5 cases have remained cancer-free, and the average observation period was 29. 3 months. One case expired due to an unrelated cause as a result of cardiac disease, while in the remaining case, the tumor did not disappear and the patient died due to the disease. It is necessary to continue examining the survival rate by increasing the number of cases.

[Noticeable clinical response to S-1/CDDP combination therapy for Virchow node recurrence after surgery for advanced gastric carcinoma with marked involvement of the esophagus - report of a case].
We have recently experienced a case in which S-1/CDDP combination therapy proved remarkably efficacious for a rapid, extensive lymph node recurrence with metastasis into a Virchow node that had developed after resection of advanced gastric carcinoma accompanied with a marked invasion of the esophagus. The patient, a woman aged 73, underwent a total gastrectomy upon left thoracolaparotomy for a gastric carcinoma at the cardia with a 5-cm involvement of the esophagus. On day 65 post-operation, a diagnosis of Virchow node and para-aortic lymph node recurrence was made on the basis of CT scan findings. Of tumor markers checked, CEA and CA19-9 were noted to be increased to as high as 37.55 ng/mL and 3,235 U/mL, respectively. The patient received three courses of S-1/CDDP combination therapy, with a consequent noticeable contraction of the Virchow node and enlarged para-aortic lymph node. Further, she was given two courses of S-1 therapy, which resulted in normalization of tumor markers. The patient has since been on continued chemotherapy without any sign of recurrence.

[Safe and successful chemoradiotherapy for a patient with cardiac pacemaker and triple cancers].
The patient was a 70-year-old male with superficial hypopharyngeal cancer and advanced cancers of the esophagus and stomach. In his past history, a cardiac pacemaker was implanted for sick sinus syndrome. Further examination showed esophageal cancer had metastasized to the cervical lymph nodes and invaded the trachea. There was no surgical indication. In terms of chemoradiotherapy, it was thought to be possible because the patient was not pacemaker- dependent and radiotherapy could be planned in such a way as to keep the dose to the pacemaker as low as possible. Electrocardiogram was monitored during the treatment. In addition to the usual observation, the patient's cardiac symptoms and pacemaker status were assessed before and soon after the completion of radiotherapy. S-1 was selected as a concomitant chemotherapy. In liaising with the cardiologist and radiologist, chemoradiotherapy was achieved without pacemaker malfunction, and shrinking of tumors was also detected.

[A case of chemo-radiation therapy with high degree of efficacy for esophageal cancer with liver metastasis].
A 78-year-old man underwent a radical resection for esophageal cancer (Stage III) and cardiac gastric cancer (Stage IA) at another hospital 2 years ago. After the operation, he was followed at that hospital. In 2008, abdominal CT scan and FDG-PET/CT revealed a liver tumor. He was referred to our hospital and was diagnosed as esophageal cancer with liver metastasis. He received chemo-radiation therapy (CRT). The regimen was docetaxel hydrate (30 mg/m2, day 1, 8, 29 and 36) and S-1 (60 mg/m2, day 1-14 and day 29-45) with radiation (45 Gy) for liver metastasis. He finished the CRT without any hematotoxicity, liver disorder and non-hematotoxic adverse event (grade 3). Abdominal CT was done 2 months after the end of CRT and revealed that the tumor lesion disappeared completely. The patient is alive for 11 months after the CRT without any evidence of recurrence. The tumor disappeared completely for the last 11 months. We conclude that CRT is safe and very effective for esophageal cancer with liver metastasis.

[A case of recurrent gastroesophageal junction adenocarcinoma successfully treated with radiation plus chemotherapy (5-FU+CDDP, S-1, Paclitaxel, CPT-11) for long-term survival with good QOL].
We report a 63-year-old man with recurrent gastroesophageal junction adenocarcinoma. He underwent esophagogastrectomy in August 2004. After curative operation with Stage III (pT3N1M0), a recurrence was found at the anastomosis site in November 2004. Chemoradiotherapy with S-1 followed by chemotherapy (S-1) was performed from January 2005 to April 2006. Lymphnode metastasis to the left side of the main bronchus appeared in May 2006, and paclitaxel was used until December 2007 when PR was indicated by CT scan and GIF. Now he is receiving CPT-11. During these 3 years and 3 months, his performance status was maintained from 0 to 1.

[A 14-month surviving patient on advanced esophageal cancer with big lymph node metastasis to cardia responding to S-1 plus cisplatin (CDDP) therapy at home].
This case was a 70s male patient. He was hospitalized with some dysphasia and a severe body weight loss since August 2004. The diagnosis was the esophageal cancer (type 2, 11 cm) with big lymph node metastasis on cardia (8 cm), and also pathologically poorly differentiated squamous cell carcinoma from two legions. He wanted a home chemotherapy for it. We administered a combination chemotherapy of S-1 plus cisplatin (CDDP) therapy. An eight-day admission within an each course to CDDP treatment and nutritional support were required for adverse events of anorexia (grade 3), but for other days home chemotherapy was done with good compliance of S-1 up to 6 courses. After 2 courses, endoscopic findings showed a pathological complete response of esophageal mass, and CT findings also showed a partial response of the lymph node. After 6 courses of S-1 + plus cisplatin in May 2005, a home S-1 single therapy which was not needed the admission started at will. But the lymph node mass of cardia progressed again in September 2005, and his therapy moved to the terminal care at home.

[Complete response in a case of advanced esophageal cancer treated with docetaxel/5-FU/CDDPand S-1/docetaxel as neoadjuvant chemotherapy].
A 64-year-old woman with advanced esophageal cancer underwent chemotherapy with docetaxel/5-FU/CDDP (DFP). Adverse reactions were severe nausea and general fatigue, so the patient decided to discontinue DFP therapy. The treatment was changed to S-1/docetaxel. Adverse reactions were not so severe, so she could receive 1 course of the medication completely. After the treatment, the primary lesion showed a partial response, so we performed surgery. In the resected specimen, no malignant cell could be seen microscopically. Though the advanced esophageal cancer was regarded as a systemic disease, the appropriate combination of chemotherapy and surgery proved effective.

[Recurrent esophageal cancer with complete response to TS-1 chemotherapy].
An 80-year-old man was admitted to our hospital for treatment of recurrent esophageal cancer in December, 2004. He was diagnosed as having esophageal cancer of stage IVa (T2N4M0) in October, 2002, and he received chemoradiotherapy (nedaplatin (CDGP)/5-fluorouracil (5-FU) total 6 course+60 Gy). Afterwards, lymph nodes recurred, and two courses of CDGP/vindesine were given. Then, the primary lesion showed a complete response (CR), and lymph nodes a partial response (PR). In December, 2004, paraesophageal lymph nodes were enlarged to the size of 7 cm. On admission, because of renal disturbance and dementia with advanced age, we chose chemotherapy with TS-1 (100 mg/body/day, three weeks of administration, then two weeks of withdrawal). He had adverse effects of hematotoxicity of grade 3, and non-hematotoxicity of grade 1. He received 6 courses of this regimen and eventually showed CR. Serum SCC was decreased from 4.7 ng/mL to 0.9 ng/mL. At present,the lesions have not recurred during the follow-up for 18 months.

Successful treatment of S-1 + CDDP followed by salvage EMR for a case with metastatic Barrett's esophageal cancer.
A 62-year-old woman with Barrett's esophageal cancer was hospitalized. Abdominal CT confirmed metastases to the liver and lymph nodes, for which surgical excision and radiotherapy were not indicated. We started chemotherapy with a course of daily oral S-1 at a dose of 80 mg/m(2) for 21 days, with a 2-hour drip of cisplatin at 60 mg/m(2) on day 8. Breaks of 14 drug-free days were given between courses. After two courses, a repeat CT confirmed that the liver and lymph node metastases had disappeared; after three courses, another CT confirmed that the metastatic foci were still absent, so we judged the disease to be in complete remission. Endoscopy and upper GI series confirmed that the primary tumor was reduced, and endoscopic mucosal resection performed using the strip biopsy method. The excision specimen was well differentiated adenocarcinoma, and mucosal invasion, and the excision stump was negative. After two more courses of S-1 + cisplatin, chemotherapy has been suspended with the patient's consent, and in the 21 months after endoscopic mucosal resection, no recurrence has been observed. This is a rare case of metastatic Barrett's esophageal cancer in which the metastases were eradicated by S-1 + cisplatin, and the primary tumor successfully excised by endoscopic mucosal resection after downstaging.

[Resection of cancer of the cardia enabled by combined treatment with S-1 and paclitaxel after esophageal stenting for impaired patency complicating stage IV gastric cancer - a case report].
The patient was a 47-year-old man who was discovered to have Borrmann type 4 cancer of the cardiac region of the stomach associated with esophageal invasion during upper GI endoscopy and was histopathologically diagnosed with poorly-differentiated adenocarcinoma. Invasion of the aorta was suspected based on a CT examination, and resection was judged to be impossible. Since the tumor was associated with impaired patency, after first inserting a metallic stent, the patient was treated with 4 cycles of S-1 100 mg/body for 2 weeks and paclitaxel (PTX) 120 mg/body by intravenous drip infusion on days 1 and 15 for 2 weeks followed by a 2-week rest period. The tumor regressed considerably, and total gastrectomy and lower esophagectomy with D1+ a lymph node resection through a left thoracolaparotomy became possible. A bypass operation or palliative resection is sometimes performed when complicated by impaired patency. In our patient, after achieving an improvement in QOL by stenting, resection became possible as a result of a response to chemotherapy with S-1. However, when considering resection after chemotherapy it seemed necessary to be careful to insert the stent as close as possible to the proximal margin of the tumor so as not to broaden the extent of the esophageal resection.

[S-1 chemotherapy for cancer of the gastric tube used for esophageal reconstruction following surgery for esophageal cancer].
We used S-1 chemotherapy to treat 5 patients with cancer of the gastric tube used for esophageal reconstruction through the posterior mediastinal route following surgery for esophageal cancer. The response rate was 40%, the median survival 15 months, and 3 patients still survive. In those 3 patients, the gastric tube cancer was at a resectable stage, but the patients elected to have chemotherapy instead. One patient has survived 21 months after responding completely to 2 cycles of combined chemotherapy with S-1 and cisplatin. Another has survived 15 months after partially respondingto S-1 chemotherapy. And the third has survived 46 months after endoscopic treatment, radiation therapy and S-1 chemotherapy. S-1 chemotherapy thus appears to be an effective treatment for cancer of the gastric tube after surgery for esophageal cancer.

[Complete recovery obtained with combined S-1 + CDDP therapy in a patient with multiple lung metastases from esophageal cancer].
There are numerous reports on the subject of effectiveness in radio-chemotherapy with regard to esophageal cancer, suggesting especially the combination therapy of 5-FU + CDDP aimed for recovery. Treatment becomes difficult when distal metastases appear during an adjuvant therapy followed by surgery. Our report here is a case in which a complete recovery was obtained after changing to S-1, a prodrug of 5-FU, in response to multiple lung metastases which appeared during the combined 5-FU + CDDP therapy followed by surgery for esophageal cancer.. The patient was a 71-year-old male. Endoscopy during a physical examination showed a Type 1 tumor 27-30 cm from the anterior teeth. Detailed tests provided a preoperative diagnosis of esophageal cancer: Ut Type 1, T2-T3, N2, MO, IMO. A right thoracolaparotomic subtotal esophagectomy and retrosternal reconstruction were performed. Pathological findings showed well-differentiated squamous cell carcinoma, pT1b (sm), pN1 (106-rec R), pStage II. Postoperative combination of 5-FU + CDDP (day 1-5, 5-FU 500 mg; CDDP 10 mg/body) was started. Because of the appearance of multiple lung metastases after the completion of 3 courses, 2 courses of S-1 + CDDP (S-1 120 mg/body day 1-14; CDDP 5 mg/body day 1-5, day 8-12) were performed. After completing the chemotherapy, CT revealed the resolution of the lung metastases and complete recovery was diagnosed. Following this, a treatment with S-1 alone was continued until the appearance of bone metastases at which time radiotherapy was performed. The treatment is currently ongoing and no recurrence of the lung metastases has been shown.. There have been numerous reports of the combination of S-1 + CDDP in esophageal cancer for NAC or in inoperable cases. However, our report suggests that this method may be effective in cases of recurrence or distal metastases.

[Experimental chemotherapy against human esophageal carcinoma xenografts with TS-1, cisplatin and docetaxel].
Three strains of human esophageal carcinoma xenografts established in our institution were tested against combination chemotherapy in vivo and in vitro. TS-1 plus cisplatin (CDDP) was shown to be an effective combination against two carcinoma strains of moderately-differentiated type. Determination of the thymidylate synthase (TS) demonstrated a higher inhibition of the enzyme by adding CDDP to 5-FU, suggesting biochemical modulation. The remaining strain of poorly-differentiated type was resistant to the combination and an attempt was made to add docetaxel (DTX) to show that the three-drug combination was effective against the strain. Combination chemotherapy including TS-1 and CDDP thus appears to be useful treatment choice for esophageal carcinoma.

[A case of recurrent esophageal cancer responding to second-line chemotherapy of TS-1/docetaxel combination].
A 70-year-old man suffering from advanced esophageal cancer (Stage II) underwent subtotal esophagectomy in December 2000. He then had postoperative chemotherapy, called low-dose FP, and was followed in an ambulatory setting. In December 2003, he was diagnosed as a recurrence of esophageal cancer with multiple liver metastases and upper mediastinum lymph node, so he was treated by combined chemotherapy consisting of TS-1 and docetaxel as a second-line chemotherapy. After 3 courses of this therapy, CT scan showed that the size of liver and lymph node metastases was reduced and the effect of this therapy was PR. PR continued for about 6 months. This chemotherapy made it possible to treat liver and lymph node metastasis in an ambulatory setting. It is conceivable that this combination chemotherapy might be a promising regimen for a short period.

[Combination chemotherapy of TS-1, docetaxel and CDDP produces a remarkable response in a patient with advanced esophageal cancer].
We report a patient with advanced esophageal cancer who achieved a complete response to combination chemotherapy of TS-1, docetaxel and CDDP. A 74-year-old man was admitted to our hospital for advanced esophageal cancer with a complaint of dysphagia. He received chemotherapy, consisting of TS-1 100 mg/body, docetaxel 35 mg/m(2), and CDDP 10 mg/m(2), every 3 weeks. TS-1 was administered for 14 days followed by 7 days rest; docetaxel and CDDP were administered by intravenous infusion at day one and day 8 after beginning TS-1. After three cycles of chemotherapy, his dysphagia disappeared, and endoscopic examination of the primary esophageal tumor showed a complete response. Endoscopic examination with biopsy confirmed the disappearance of the esophageal cancer. No severe side effects were observed during this chemotherapy. Combination chemotherapy of TS-1, docetaxel, and CDDP can thus be effective for advanced esophageal cancer.

A case of early relapsed multiple lung metastases after esophagectomy successfully treated with S-1/cisplatin therapy after docetaxel/5-fluorouracil/cisplatin therapy.
A 55-year-old-male patient underwent subtotal esophagectomy for esophageal cancer (pT1b, N0, M0, stage II) in April 2005. The patient received postoperative chemotherapy (docetaxel 40 mg/body, 5-fluorouracil 750 mg/body, cisplatin 10mg/body: administered every 4 weeks) for 3 months. Six months postoperatively, routine follow up CT demonstrated multiple metastatic tumors in the bilateral lungs. Under the diagnosis of multiple lung metastases, the patient was hospitalized and received intensive chemotherapy with docetaxel 40 mg/week (day 1), 5-fluorouracil 500 mg/day (days 1-5), cisplatin 10 mg/day (days 1-5). After two weeks administration, the patient eagerly hoped for outpatient treatment. The treatment was changed to outpatient chemotherapy with S-1 100 mg/day (continuous administration for 3 weeks followed by rest for 1 week) and cisplatin 20 mg/every week. The treatment enabled the patient to keep working. Follow up CT showed disappearance of all tumors two months after TS-1/cisplatin chemotherapy. There were no obvious signs of recurrence 5 months after chemotherapy. The S-1/cisplatin therapy in the outpatient was thought to be one of the effective treatments in maintaining quality of life for the patient.

A 78-year-old man was admitted to our hospital complaining of dysphagea on April 8, 2005. Upper gastrointestinal endoscopic examination showed type 2 esophageal cancer in the lower thoracic area and type 3 gastric cancer in the upper body. Computed tomography showed No. 3 lymph node swelling, but no distant metastasis. Surgery was contraindicated because of many complications, so the patient was given combined chemotherapy with TS-1 and low-dose cisplatin. Chemotherapy was started on April 18. After 2 courses of chemotherapy the esophageal lesion showed a complete response, and after 5 courses the gastric lesion evidenced a complete response.

[Pilot study of concomitant TS-1/CDGP radiotherapy for esophageal cancer].
Although surgery is treatment of choice for esophageal cancer, radiochemotherapy is being employed throughout Japan for the purpose of improving patient QOL. The results of this therapy are reported to be comparable to those associated with surgical treatment. However, since concomitant 5-FU/CDDP radiotherapy, currently the treatment of choice when implementing radiochemotherapy, is associated with a comparatively high incidence of gastrointestinal disorders and requires continuous intravenous infusion for 24 hours, it lowers the level of patient QOL. We have proposed a clinical study of concomitant TS-1/CDGP radiotherapy for the purpose of maintaining patient QOL and improving outcome. We conducted a pilot study prior to the phase I and II studies. The study was conducted on six cases and favorable results were obtained, consisting of a CR rate of 66.7% and a two-year survival rate of 50%. Although bone marrow inhibition was observed as an adverse side effect, gastrointestinal disorders that were discernible to the patients were extremely mild, and patient QOL was able to be maintained. CR was observed in 2 cases who were positive for DPD as determined by immunostaining. We are planning on conducting phase I and II studies in the future based on the potential for this treatment to contribute to the preservation of patient QOL and improve prognosis.

[Complete response in a case of advanced esophageal cancer treated by combined chemotherapy of TS-1 and CDDP with radiotherapy].
A 70-year-old patient with advanced esophageal cancer with invasion to the aorta was treated by combined chemotherapy of TS-1 and CDDP with radiotherapy. TS-1 (80 mg/m2) was administered for 14 days followed by 14 days rest, CDDP (70 mg/m2) was administered by 24 h continuous intravenous infusion at day 8 after the start of TS-1. Radiotherapy (5 days/week) at 2 Gy/day was concurrently started from the beginning of chemotherapy for 3 weeks. After the end of the first course, leukocytopenia of grade 2 and thrombocytopenia of grade 2 were observed. The second course of chemoradiotherapy was suspended for 1 week. After recovery from the toxicity, the second course was started. After the 2 courses of chemoradiotherapy, endoscopic examination with biopsy revealed the disappearance of the esophageal cancer. Combined chemotherapy of TS-1 and CDDP was administered 2 times after chemoradiotherapy. After this therapy, endoscopy and a CT showed a complete clinical response. No severe adverse effects were observed during this therapy. Combined chemotherapy of TS-1 and CDDP with radiotherapy can be effective for advanced esophageal cancer.

[A case of synchronous esophageal and gastric cancer successfully treated by combination TS-1/CDDP therapy with irradiation].
We report a case of synchronous esophageal and gastric cancer in a patient with severe liver dysfunction who was treated successfully using TS-1/CDDP therapy combined with irradiation therapy. A 56-year-old man with a chief complaint of dysphagia was diagnosed with thoracic esophageal cancer by endoscopy, and was referred to our hospital. Synchronous esophageal and gastric cancer were diagnosed by endoscopy and barium swallow. The preoperative diagnosis was T3N0M0, Stage II esophageal cancer and T1N0M0, Stage I A gastric cancer, both of which were diagnosed to be resectable. However, surgery was contraindicated because of severe liver dysfunction, due to an ICG15 of 35%. TS-1 (80 mg/day) and CDDP (3 mg/day) therapy was combined with irradiation, 60 Gy given in a T-pattern to the mediastinum. The patient did not suffer any side-effects, and endoscopy performed 44 days after the start of treatment showed that the esophageal lesion was now only a scar. Only a slight elevation of the esophagus was seen by endoscopy 219 days after the start of the therapy. The patient is currently undergoing only TS-1 treatment as an outpatient and is under observation. No metastasis to the liver or any other organ has been detected. TS-1 and CDDP therapy combined with radiotherapy appears to be effective in treating thoracic esophageal cancer.

[A case of Barrett's esophageal carcinoma successfully treated with TS-1 in an elderly patient].
A 92-year-old man was admitted to the hospital for rehabilitation. Upper gastrointestinal endoscopy was performed 2 weeks after admission because of vomiting which was found to be due to a Barrett's esophageal carcinoma at the lower esophagus. We chose chemotherapy with TS-1 at the dose of 50 mg/day in consideration of his age and performance status. His difficulty in swallowing disappeared rapidly. After 7 days of treatment, grade 3 anorexia appeared, so the dosage of TS-1 was reduced to 25 mg/day. After the reduction of TS-1, anorexia soon disappeared. The regimen consisted of TS-1 every 6 weeks as 1 cycle. After 7 cycles of treatment, upper gastrointestinal endoscopy and upper gastrointestinal series revealed that the tumor had a completely disappeared. The effects of chemotherapy were judged as CR. This case suggests that administration of TS-1 is an effective choice of chemotherapy not only for gastric carcinoma but also Barrett's esophageal carcinoma.

[A case of metastatic esophageal cancer responding remarkably to combination chemotherapy of TS-1 and cisplatin].
A 51-year-old male patient with esophageal cancer and cervical, thoracic and celiac artery lymph node metastases was treated by combination chemotherapy of TS-1 and cisplatin. TS-1 (80 mg/m2/day) was administered for 14 days followed by 14 days rest as 1 course. Cisplatin (70 mg/m2/day) was administered in 24-hour continuous intravenous infusion at day 8 after the start of TS-1. Before treatment, the tumor marker, CEA showed 27,060 ng/ml. After 5 courses of chemotherapy, endoscopy revealed that the primary tumor had disappeared and no cancer cells were detected by endoscopic biopsy. Chest and abdominal CT scan also showed almost total disappearance of the lymph nodes metastases. CEA decreased to 710 ng/ml. No high-grade toxicities (WHO grade 3 or 4) were seen during the chemotherapy. He is now very well. This TS-1/cisplatin chemotherapy regimen might be a useful treatment for metastatic esophageal cancer.

[A case of advanced cervical and upper thoracic esophageal carcinoma completely responding to chemoradiotherapy with TS-1 and cisplatin].
A 52-year-old man was hospitalized for evaluation of dysphagia. Esophagography depicted an irregular narrowing extending 7 cm from the cervical esophagus to the upper thoracic esophagus. Esophagoscopy with biopsy showed cervical esophageal cancer narrowing the lumen. Surgery was contraindicated because of a previous cardiac infarction. The patient selected concurrent chemoradiotherapy with TS-1 and cisplatin. The first course included 30 Gy of radiotherapy given over 3 weeks, together with daily oral administration of TS-1 (120 mg/day) for 2 weeks, and a 24-h infusion of cisplatin (70 mg/m2) on day 8. After a second course of chemoradiotherapy, 4 courses of chemotherapy with TS-1 and cisplatin were administered at 4-week intervals. After additional chemotherapy, esophagoscopy and cervical CT showed that the primary lesion had disappeared. Two years after initial hospitalization, no recurrence has been detected.

Esophageal cancer with colonic metastasis successfully treated by chemoradiotherapy followed by chemotherapy with S-1 and cisplatin.
A 51-year-old man was hospitalized for evaluation of dysphagia and bloody stool. Gastrointestinal endoscopy showed esophageal cancer invading the gastric fundus. A metastatic lesion was demonstrated in the sigmoid colon. The patient agreed to have concurrent chemoradiotherapy for the primary lesion, followed by additional chemotherapy. The first course included 30 Gy of radiotherapy given over 3 weeks, together with daily oral administration of S-1 (80 mg/m2 per day) for 2 weeks, and a 24-h infusion of cisplatin (70 mg/m2) on day 8. After a second course of chemoradiotherapy, four additional courses of chemotherapy with S-1 and cisplatin were administered, at 4-week intervals. After the additional chemotherapy, gastroscopy and colonoscopy showed disappearance of both the primary and the metastatic lesions. One year after his initial hospitalization, no recurrence of either the primary or the metastatic tumor lesions is evident.

[A case of advanced esophageal cancer responding remarkably to chemotherapy of TS-1 and weekly CDDP combined with radiotherapy].
A 66-year-old patient, who had advanced esophageal cancer with lymph node metastasis, was treated by neoadjuvant chemo-radiotherapy, followed by curative surgery. Chemotherapy of TS-1 (80 mg/m2) was administered orally for 21 days, and weekly intravenous administration of CDDP (20 mg/m2) was done 3 times. Radiotherapy at 2 Gy/day was combined 15 times (total 30 Gy). The tumor responded well to the treatment, and the size was remarkably reduced. Chemoradiotherapy using TS-1 and weekly CDDP revealed their efficacy for esophageal cancer.

[A case of Barrett's esophageal cancer showing good response to combined chemotherapy with TS-1, CDDP and radiotherapy].
The patient was a 69-year-old man who, during a routine health examination, was found to have irregular mucosa in the lower esophagus, which was subsequently diagnosed by endoscopy as Barrett's esophagus. Endoscopic ultrasonography led to the diagnosis of advanced esophageal cancer with a depth of invasion corresponding to T2. While surgery was indicated, it was not considered feasible because of pleural adhesions due to old tuberculosis. Therefore, chemotherapy with TS-1 at the dose of 80 mg/day (4-week therapy followed by a 2-week withdrawal period) and CDDP at the dose of 3 mg/day (4-week of 5-day therapy followed by a 2-day withdrawal period) was instituted, followed 3 weeks later by the addition of radiotherapy with 1.8 Gy/day (5 times/week). Follow-up endoscopy revealed evident reduction in the lesion size 73 days after the start of TS-1 therapy, and complete disappearance of the lesion 185 days after the start of therapy. Grade 1 leukopenia was the only adverse effect of TS-1 noted in the patient. Treatment of Barrett's esophageal cancer is often conducted in accordance with the principles of treatment of esophageal squamous cell carcinoma, and surgical resection represents the most effective treatment. On the other hand, there have been no reports of effective adjuvant therapy. Based on our experience, the therapeutic strategy employed in this patient is considered to offer promise for the treatment of Barrett's esophageal cancer.

[Remarkable response of simultaneous advanced esophageal and gastric cancer to combined chemotherapy with weekday-on/Weekend-off TS-1 plus biweekly cisplatin].
A 66-year-old man was found to have both advanced cancer of the middle thoracic esophagus and advanced cancer of the middle third of the stomach with paraaortic lymph node metastases. The prognosis was poor because of local advanced disease and distant metastasis. The patient was therefore given combined chemotherapy with TS-1 and cisplatin. TS-1 (80 mg/day) was administered on days 1 to 5, 8 to 12, 15 to 19, and 22 to 26 (weekday-on/weekend-off schedule), and cisplatin (70 mg/m2 intravenously over the course of 2 hours) was administered on days 1 and 15 of a 28-day cycle. After 2 courses of chemotherapy the esophageal lesion had a complete response, and the gastric lesion had a partial response (reduction ratio, 71.4%). However, stomatitis and anorexia of grade 2 (NCI-CTC) occurred. Two courses of TS-1 alone (80 mg/m2) were therefore given. The esophageal lesion continued to show a complete response and the gastric lesion a partial response (reduction ratio, 85.7%). There was no change in the para-aortic lymph node metastasis (No. 16a2 latero). No adverse reaction to chemotherapy was severer than grade 3, and a good response was obtained. These findings indicate that chemotherapy with a combination of TS-1 and cisplatin is effective against advanced esophageal cancer and advanced gastric cancer.

[A patient with advanced gastric cancer that response remarkably to combination chemotherapy of TS-1 and biweekly paclitaxel (TXL)].
We treated a patient with inoperable advanced gastric cancer and malignant ascites by combination chemotherapy of TS-1 and biweekly paclitaxel (TXL). After two courses the ascites had disappeared and the primary tumor was reduced. TS-1 (80 mg/body/day) was administered for 21 days followed by 7 days rest and TXL (100 mg/body) was administered on days 1 and 14 as one course. The patient could not eat at the time of hospitalization, but at the time of the second course he could eat a full serving of rice porridge. Grade 2 anemia and leukopenia were the only adverse reactions observed; no major adverse reactions were observed. These results suggest that with TS-1 and TXL combination chemotherapy, patients with advanced gastric cancer can achieve a marked improvement in quality of life.

[A case of residual gastric cancer accompanied by esophageal invasion in which residual lesions were eradicated by half-dose administration of TS-1].
The patient was a 64-year-old male. On November 21, 1991, he underwent gastric resection on the pyloric side for early gastric cancer in the authors' hospital, and did not experience recurrence for many years thereafter. However, endoscopic examination of the upper gastrointestinal tract performed on June 11, 1999 revealed advanced cancer in the posterior wall of the residual stomach which was accompanied by invasion of the esophagus. Thus, the residual stomach was completely removed on July 5, 1999. The histopathological findings were tub1, se, ly3, v2, aw(-), ow(+) and ew(+), and a portion of the esophageal stump and the serosa of the lesser curvature were positive for cancerous tissue. Endoscopic examination was performed one month after the operation, on August 7, 1999. A forceps biopsy taken from an elevated lesion of the esophagus at the posterior wall of the anastomosis revealed adenocarcinoma cells in the lower layer of the squamous epithelium. A residual esophageal lesion was thus diagnosed. Beginning on August 9, 1999, TS-1 was administered in a dosage of 50 mg bid, but it was later learned that the patient had ingested only half of that TS-1 dosage (i.e., 50 mg/day). After completion of one course of this therapy, endoscopy was again performed. It was found that the prominence on the esophageal mucosa at the anastomosis, which had been diagnosed as being cancerous tissue, had shrunk in size, while a forceps biopsy taken from the same site yielded no findings of malignancy. The patient was followed for 18 months thereafter, and endoscopy was performed three times during that interval but continued to yield no evidence of malignancy. As of February 2001, this patient had completed 12 courses of TS-1 at one-half its usual dosage. There have been no findings of recurrence, and the patient's course continues to be good. In summary, this was an interesting case in which residual cancer was detected in the esophageal stump following resection for gastric cancer, and it can be concluded that TS-1 therapy was effective in spite of being incomplete (i.e., half-dose), eradicating the residual cancer tissue.

[Complete response in a case of simultaneous esophageal and gastric cancer treated by combined radiotherapy and chemotherapy of TS-1 and CDDP].
A 75-year-old male patient was hospitalized for examination of abdominal trouble. Endoscopic examination simultaneously revealed 0-I pl + II c esophageal cancer and type 3 gastric cancer. Endoscopic treatment is impossible to resect the lesion completely. It is difficult for the patient to undergo an operation because he has suffered from a cardiac infarction and pulmonary trouble. Thus, gastric cancer was treated by chemotherapy and esophageal cancer by concurrent chemoradiotherapy with chemotherapy used for gastric cancer. Chemotherapy consisted of CDDP and TS-1 every 4 weeks. TS-1 (100 mg/day) was administered on days 1 to 21, and CDDP (70 mg/m2) was infused for 24 hours on day 8. Radiotherapy (5 days/week) at 2 Gy/day was concurrently started from the beginning of chemotherapy. At day 8 in the 2nd course of chemotherapy, leucocytopenia of grade 2 and appetite loss of grade 3 (NCI-CTC) were seen. Chemoradiotherapy was then suspended for one week. After recovery from toxicity, treatment was continued for a week. A total of 64 Gy was administered. After treatment, endoscopic examination with biopsy revealed the disappearance of gastric and esophageal cancer.

[A case of gastric cancer in the stomach wall used for mediastinal reconstruction after esophagectomy in which surgery was abandoned due to advanced age and complications but TS-1 was useful].
The patient was a 78-year-old man. Gastric cancer, type 3, was diagnosed by endoscopy in the subtotal stomach used for posterior mediastinal reconstruction after resection of thoracic esophageal cancer. Surgery was not considered to be feasible in this case because of cerebral infarction and decreased pulmonary functions; instead, the patient received TS-1 chemotherapy. Drug administration was started at the dose of 100 mg/day, one level lower than the standard dose of TS-1. Reduction in tumor size was noted endoscopically during the first course of treatment. At the end of the 4th course of treatment, the ulcerous lesion was found to have disappeared almost completely, and only mild mural irregularity was noted. The incidence of gastric cancer in the stomach tissue used for mediastinal reconstruction after esophagectomy has been reported to be 0.8%. In many of these cases, the cancer is already advanced at the time of diagnosis, precluding surgical resection. In this situation, chemotherapy with TS-1 is expected to be an effective method of treatment that can be administered at home in elderly patients with a variety of complications.
