Bladder involvement by a secondary tumor is fairly rare and an uncommon source of bladder metastasis is the stomach.. The authors report a case of a 38-year-old man with a bladder metastasis from a gastric signet-ring-cell (SRC) adenocarcinoma who presented with ematuria. The clinical history and the presence of SRCs in the voided urinary cytology and histologically in the suburothelial connective, with an overlying intact urothelium suggested a diagnosis of bladder metastasis from gastric carcinoma.. Bladder involvement by a secondary tumor is very rare, and a SRC carcinoma metastatic to the bladder, albeit extremely rare, should be considered in the differential diagnosis.

Whether gastric cancer in young adults differs from gastric cancer in older patients has been a controversial issue. It has long been suspected that young patients with gastric cancer have different biological features with a more aggressive course of disease and a poorer prognosis than older patients. This, however, has not been firmly substantiated. We report on the clinical course of four patients (three female and one male) with locally advanced (n = 1) or metastasized (n = 3) non-resectable gastric cancer diagnosed under the age of 29 years (23, 25, 27, 28 years). Prior to diagnosis, all three women had recently been pregnant (1-22 months). Diagnosis was endoscopically biopsy-proven and staging work-up was performed by primary explorative surgery (n = 1), laparoscopy and explorative surgery (n = 1) or CAT scan and ultrasound (n = 2). The delay between initial symptoms and diagnosis was 8-22 weeks (median, 10 weeks). The histology was signet-ring cell (n = 2) or undifferentiated (n = 2) gastric cancer. All patients had the diffuse type of gastric cancer according to Lauren. Patients were treated with the FLAP polychemotherapy regimen consisting of leucovorin, 5-fluorouracil, doxorubicin and cisplatinum, as previously reported. The best response after chemotherapy was partial in two patients. Two patients showed progressive disease. Secondary surgery was performed in three responding patients (one of them responded only locally). One patient achieved no evidence of disease after complete tumor resection (R0). In two patients surgery was palliative (R2/exploration). Three patients died 6, 4 and 8 months after diagnosis. One patient is still alive. In our series, very young adults with gastric cancer had adverse clinical and pathological features. In accordance with other reports, we observed a predominance of female patients and a possible association with recent pregnancies. Though the delay between the first symptoms and diagnosis in our patients was no different from that reported for older patients, special emphasis should be given to prompt referral and diagnostic investigations, ensuring the diagnosis of gastric cancer early in the course of disease.

Based upon preclinical data showing synergy with mTOR inhibition and platinum chemotherapy, this study explores the safety and tolerability of combining everolimus with mFOLFOX6 for patients with metastatic gastroesophageal adenocarcinoma.. Eligible patients with metastatic gastroesophageal adenocarcinoma received standard-dose mFOLFOX6 chemotherapy in combination with escalating doses of everolimus.. Six patients were accrued to the first dose level of 2.5 mg everolimus daily with mFOLFOX6. Overall, the toxicity profile was manageable with expected grade 3 toxicities of mucositis and neutropenia. The dose-limiting toxicity (DLT) included a week delay in therapy greater than 7 days as a result of the first 2 courses of mFOLFOX6. Two patients experienced DLTs at the first dose level due to delays in their treatment caused by prolonged grade 2 neutropenia and fever with fatigue. They were allowed to continue with a dose reduction of their chemotherapy. The median overall survival and progression-free survival were 20.3 and 14.5 months, respectively.. The combination of mFOLFOX6 and everolimus is an active regimen with 83% of the patients experiencing a partial response. p53 mutations were found in the 5 samples analyzed.

Previous studies demonstrated survival benefits in association with the addition of chemoradiotherapy after surgery in gastric cancer. This study aimed to examine the efficacy in terms of loco-regional control and survival and safety of 5-FU-based adjuvant chemoradiotherapy after D2 curative surgery.. This study included 228 patients (81 female, 147 male) treated for gastric cancer with curative surgery plus adjuvant chemoradiotherapy. Majority of the patients underwent at least D2 lymph node resection. Median three cycles of fluorouracil chemotherapy were administered, and 45-Gy radiotherapy was delivered at 1.8 Gy/fraction concomitantly during the second cycle of chemotherapy. Local control, regional control, distant metastasis and overall survival rates were estimated.. The median age of the patients was 54 years (range 25-74 years). The most common grade III toxicities were nausea (10%) and neutropenia (9%). During radiotherapy, grade IV local skin reaction occurred in one patient. Median duration of follow-up was 47 months. Local, regional and distant recurrence developed in 9 (4%), 41 (18%) and 45 (20%) patients, respectively. Overall 5-year survival rate was 57.2%, and disease-free 5-year survival rate was 53.8%. Multivariate analysis identified less than 15 lymph node involvement as an independent predictor of better survival (p < 0.001).. Concomitant 5-FU-based chemoradiotherapy seems to be an effective and tolerable adjuvant regimen on local control and survival in curatively resected node-positive stomach cancer, particularly when combined with D2 resection.

Postoperative chemoradiotherapy (CRT) of gastric carcinoma improves survival among high- risk patients. This study was undertaken to analyse long-term survival probability and the impact of certain covariates on the survival outcome in affected individuals.. Between January 2000 and December 2005, 244 patients with gastric cancer underwent adjuvant radiotherapy (RT) in our institution. Data were retrieved retrospectively from patient files and analysed with SPSS version 21.0.. A total of 244 cases, with a male to female ratio of 2.2:1, were enrolled in the study. The median age of the patients was 52 years (range, 20-78 years). Surgical margin status was positive or close in 72 (33%) out of 220 patients. Postoperative adjuvant RT dose was 46 Gy. Median follow-up was 99 months (range, 79-132 months) and 23 months (range, 2-155 months) for surviving patients and all patients, respectively. Actuarial overall survival (OS) probability for 1-, 3-, 5- and 10-year was 79%, 37%, 24% and 16%, respectively. Actuarial progression free survival (PFS) probability was 69%, 34%, 23% and 16% in the same consecutive order. AJCC Stage I-II disease, subtotal gastrectomy and adjuvant CRT were significantly associated with improved OS and PFS in multivariate analyses. Surgical margin status or lymph node dissection type were not prognostic for survival.. Postoperative CRT should be considered for all patients with high risk of recurrence after gastrectomy. Beside well-known prognostic factors such as stage, lymph node status and concurrent chemotherapy, the type of gastrectomy was an important prognostic factor in our series. With our findings we add to the discussion on the definition of required surgical margin for subtotal gastrectomy. We consider that our observations in gastric cancer patients in our clinic can be useful in the future randomised trials to point the way to improved outcomes.

This study was conducted to evaluate the efficacy and safety of combination chemotherapy with biweekly paclitaxel plus infusional 5-fluorouracil (5-FU) and leucovorin as first-line treatment for patients with advanced gastric cancer.. Eligible patients with histologically confirmed advanced or metastatic gastric cancer were enrolled. The chemotherapeutic regimen consisted of paclitaxel (100 mg/m(2) on day 1) as a 3-hour intravenous infusion, followed sequentially by leucovorin (400 mg/m(2) on day 1) as a 2-hour intravenous infusion, bolus 5-FU (400 mg/m(2) on day 1), and then continuous infusion 5-FU (3000 mg/m(2) on day 1) over 46 hours. Cycles were repeated every 2 weeks.. Sixty patients were enrolled (median age, 52.5 years old). Of these, 65% patients had Eastern Cooperative Oncology Group performance status of grade 2. A median of 8 cycles was administered (range, 4-12). Fifty-five patients were evaluable for response. Two patients achieved a complete response and 28 patients achieved a partial response, producing an overall response rate of 50% by intent-to-treat analysis. The median duration of response was 6.4 months (95% CI, 5.14-7.60 months). Median progression-free survival and median overall survival were 7.7 months (95% CI, 6.5-8.9 months) and 14.3 months (95% CI, 9.4-19.1 months), respectively. Hematologic toxicity was mild; grade 3 neutropenia was noted in only 6.7% of patients. Alopecia was the most common nonhematologic toxicity in 51 patients (71.4%). Grade 3 alopecia occurred in 11 patients (18.3%).. Combination chemotherapy of biweekly paclitaxel followed sequentially by infusion leucovorin, bolus 5-FU, and continuous infusion 5-FU over 46 hours is effective and well tolerated in patients with advanced gastric cancer, especially in patients with poor performance status who cannot tolerate aggressive chemotherapy regimens.

To evaluate the efficacy and safety of the combination of oxaliplatin and ELF (VP16/CF/5-Fu) regimen in the treatment of patients with advanced gastric cancer.. Oxaliplatin was given at a dose of 100 mg/m(2) i.v. 2 hours D1, calcium folinate (CF) 200 mg/m(2) i.v. 1/2 hour D1 approximately D3, 5-fluorouracil (5-Fu) 500 mg/m(2) i.v. 2 hours D1 approximately D3 and etoposide 100 mg/m(2) i.v. 3 hours D1 approximately D3. Cycles were repeated every 21 days. Efficacy and safety were evaluated every 2 cycles.. Sixty-nine patients were enrolled into the study. All cases were pathologically confirmed as gastric cancer (adenocarcinoma in 57 cases and signet ring cell carcinoma in 12 cases). 42 patients had newly diagnosed disease, and 27 patients had received previous chemotherapy. 62 patients were analyzed for response (7 complete responses and 25 partial responses) with total response rate 51.61%. The median time to progression was 5.7 months and the median overall survival was 9.2 months. The most common hematologic toxicities were anemia (29.0%), leucopenia (51.2%) and thrombocytopenia (21.2%). No grade 4 and grade 5 hematologic toxicities were observed. The most common non-hematologic toxicities were nausea (46.5%), vomiting (41.1%), peripheral sensory neuropathy (47.1%), and grade 2 alopecia (27.3%).. This oxaliplatin combined with ELF regimen shows good efficacy and acceptable safety in advanced gastric cancer patients. It is worthy to be proved as a suitable alternative regimen in this indication.

The aim of this study is to investigate the efficiency and toxicity of the FOLFOX regimen, the combination of oxaliplatin (L-OHP), 5-fluorouracil (5-Fu) and calcium folinate (CF), for patients with locally advanced or metastatic gastric cancer.. Ninety-six patients with locally advanced or metastatic gastric adenocarcinoma, including 72 males and 24 females, were treated with FOLFOX regimen: L-OHP 85 mg/m(2) iv in 2 hours on D1, CF 200 mg/m(2) iv in 2 hours on D1 and D2, 5-Fu 400 mg/m(2) iv on D1 and D2, and then continuous infusion of it at a dose of 600 mg/m(2) for 44 hours. This regimen was repeated every 2 weeks. The first evaluation was done after four cycles. The median cycle of the chemotherapy was 6 (range: 1 to 12 cycles).. Of the 96 patients with gastric cancers, 21 underwent R0 resection and afterward received adjuvant FOLFOX chemotherapy. Ten of those were still alive, while the other 11 died of the disease, with a median disease free survival time of 24.0 months and 3-year survival rate of 51.8%. The other 75 received only palliative chemotherapy due to non-operable advanced disease. Thirty of those achieved partial response (PR), the other 20 had a stable disease (SD), but the remaining 25 experienced disease progression (PD), with an overall response rate of 40.0%. The median TTP and overall survival in those 75 patients was 5.9 and 12.0 months, respectively. All 96 patients were evaluable for toxicity according to NCI criteria. The patients of grade 3 vomiting and neural toxicity were 6 and 4, respectively.. In terms of efficacy and safety, the FOLFOX regimen is effective and well tolerable for patients with locally advanced or metastatic gastric cancers either as adjuvant or palliative chemotherapy.

This nonrandomized open label phase II study evaluated the efficacy and safety of FOLFOXIRI in metastatic or recurrent gastric cancer patients.. Patients with histologically proven, metastatic gastric adenocarcinoma, aged 18-70 years, performance status zero to two, no prior chemotherapy, and with signed written informed consent were eligible. Treatment consisted of irinotecan 150 mg/m2 day 1, oxaliplatin 85 mg/m2 day 1, leucovorin 100 mg/m2 day 1, and 5-fluorouracil 2000 mg/m2 as a 48-h continuous infusion starting on day 1, which was repeated every 2 weeks.. From August 2004 to August 2005, 48 patients were prospectively enrolled. The median age was 54 years (24-69). In total, 386 cycles were administered with a median of nine cycles per patient (range 1-12 cycles) and 45 of 48 patients were assessable for treatment response. An independent review of tumor responses resulted in overall response rate of 66.7% (95% confidence interval=53.4% to 80.0%) by intent-to-treat analysis with one complete response and 31 partial responses. The median survival of all patients was 14.8 months and the median time to progression was 9.6 months. Most common grade 3/4 toxic effects were neutropenia (12% of all cycles) and emesis (8% of all cycles). Grade 2 peripheral neuropathy occurred in five patients. One (2%) patient had severe tumor bleeding and five (10%) patients experienced grade 3 diarrhea.. The modified FOLFOXIRI combination chemotherapy showed a very promising preliminary antitumor activity and was generally well tolerated as a first-line treatment of patients with metastatic gastric cancer.

The aim of the study was to assess the toxicity and the clinical activity of biweekly oxaliplatin in combination with infusional 5-fluorouracil (5-FU) and folinic acid (FA) administered every 2 weeks (FOLFOX-4 regimen) in patients with advanced gastric cancer (AGC). A total of 61 previously untreated AGC patients were treated with oxaliplatin 85 mg m(-2) on day 1, FA 200 mg m(-2) as a 2 h infusion followed by bolus 5-FU 400 mg m(-2) and a 22 h infusion of 5-FU 600 mg m(-2), repeated for 2 consecutive days every 2 weeks. All patients were assessable for toxicity and response to treatment. Four (7%) complete responses and 19 partial responses were observed (overall response rate, 38%). Stable disease was observed in 22 (36%) patients, with progressive disease in the other six (10%) patients. Median time to progression (TTP) and median overall survival (OS) were 7.1 and 11.2 months, respectively. National Cancer Institute Common Toxicity Criteria grade 3 and 4 haematologic toxicities were neutropenia, anaemia and thrombocytopenia in 36, 10 and 5% of the patients, respectively. Grade 3 peripheral neuropathy was recorded in three (5%) patients. FOLFOX-4 is an active and well-tolerated chemotherapy. Response rate (RR), TTP and OS were comparable with those of other oxaliplatin-based regimens, suggesting a role for this combination in gastric cancer.

Peritoneal cancer index (PCI) >20 is often seen as a contraindication for cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with peritoneal metastases (PM) from colorectal cancer. The aim of this study was to compare the overall survival in colorectal PM patients with PCI >20 and PCI ≤20 treated with CRS and HIPEC to those having open-close/debulking procedure only.. All patients with colorectal PM and intention to treat with CRS and HIPEC in Uppsala Sweden 2004-2017 were included. Patients scheduled for CRS and HIPEC were divided into three groups, PCI >20, PCI ≤20, and those not operated with CRS and HIPEC stated as open-close including those treated with palliative debulking.. Of 201 operations, 112 (56%) resulted in CRS and HIPEC with PCI ≤20, 45 (22%) in CRS and HIPEC with PCI >20 and 44 (22%) resulted in open-close/debulking. Median survival for CRS and HIPEC and PCI >20 was 20 months (95%CI 14-27 months) with 7% surviving longer than 5 years (n = 3). For CRS and HIPEC and PCI ≤20 the median survival was 33 months (95%CI 30-39 months) with 23% (n = 26) surviving >5years. The median survival for open-close was 9 months (95%CI 4-10 months), no one survived >5years.. Patients with PM from colorectal cancer and PCI >20 that were treated with CRS and HIPEC experience a one year longer and doubled overall survival compared with open-close/debulking patients. In addition to PCI, more factors should be taken into account when a decision about proceeding with CRS or not is taken.

We describe the case of a 74-year-old woman with previous history of gastric signet cell carcinoma who develops bladder metastasis as first sign of recurrence 6 years later. Bladder metastasis due to signet cell carcinoma is extremely rare with only 19 cases reported. Treatment includes radical cystectomy or chemotherapy.

A 52-year-old woman with epigastralgia and abdominal discomfort was admitted to our hospital. The abdominal CT scan showed that she had intestinal obstruction and peritoneal dissemination. Colonoscopy also revealed a submucosal tumor around the orifice of the appendix. Moreover, histological examination results indicated signet ring cell carcinoma. She was then treated with modified FOLFOX chemotherapy;however, the disease condition progressed after an 8-course treatment, and she died 12 months after the chemotherapy was initiated.

Currently, cytoreductive surgery and hyperthermic intraperitoneal chemotherapy are accepted treatments for surgically resectable appendiceal epithelial neoplasms. However, for nonsurgical candidates, systemic treatment may be considered. The purpose of this analysis was to determine the benefit of biologic therapy (anti-vascular endothelial growth factor and anti-epidermal growth factor receptor) in addition to systemic chemotherapy in this select patient population.. The MD Anderson Cancer Center tumor registry was retrospectively reviewed for systemic treatment-naive appendiceal epithelial neoplasm patients registered between January 2000 to July 2007 for prior cytoreductive surgery and hyperthermic intraperitoneal chemotherapy status, histologic grade, signet ring pathology, systemic chemotherapy, biologic therapy, tumor markers (carcinoembryonic antigen, carbohydrate antigen [CA] 125, and/or CA19-9), progression-free survival (PFS), overall survival (OS), and disease control rate. Kaplan-Meier method, log-rank, and Cox proportional hazard regression models were used for statistical analysis.. A total of 353 patients were identified; 130 patients met the inclusion criteria. Fifty-nine patients received biologic therapy. The use of the anti-vascular endothelial growth factor (VEGF) agent bevacizumab improved both OS (42 months vs. 76 months, hazard ratio 0.49 [95 % confidence interval 0.25-0.94] P = 0.03) and PFS (4 months vs. 9 months, hazard ratio 0.69 [95 % confidence interval 0.47-0.995], P = 0.047) for all histologic subtypes. Moderately differentiated tumors had an improved PFS relative to well-differentiated tumors, 9 months versus 3 months (P = 0.05).. Bevacizumab in combination with chemotherapy appears to play a role in surgically unresectable appendiceal epithelial neoplasm patients, with an improvement in PFS and OS. Anti-VEGF agents should be strongly considered in the management of patients with higher-grade appendiceal epithelial neoplasms who are suboptimal candidates for surgical resection.

The role of SC before CRS/HIPEC for patients with PMCA is unclear. This study explores the effect of SC prior to CRS/HIPEC on overall survival (OS) in patients with PMCA.. 72 patients with recently diagnosed PMCA who underwent CRS/HIPEC were identified from a prospective database. Thirty patients had SC before CRS/HIPEC (Group 1) and 42 did not (Group 2). Patients who were referred to our center after multiple lines of SC were excluded from this analysis. OS was estimated.. Median follow-up was 3.2 years. Groups were similar regarding lymph node positivity, postoperative SC and rate of complete cytoreduction. Twenty-four (80%) patients in Group 1 and 21 (50%) in Group 2 had high grade histology (HG) (p = 0.01). OS from CRS/HIPEC at 1, 2, and 3 years was 93, 68, 51% in Group 1 and 82, 64, 60% in Group 2, respectively (p = 0.74). Among HG patients 3-year survival was 36% in the SC group vs. 35% in the group without SC (p = 0.67). The 3-year OS for patients with low grade (LG) tumors was 100% in the SC group vs. 79% in the group with no prior SC (p = 0.26). Among patients with signet ring cell (SRC) histology, 1, 2 and 3-year survival was 94, 67 and 22% in the SC group vs. 43, 14, 14% in the group with no SC, respectively (p = 0.028). There were only 6 patients with LG PMCA who received prior SC.. Preoperative SC could improve the prognosis of patients with high-grade PMCA with SRC histology.

FOLFOX-based adjuvant chemotherapy is a benefit for high-risk stage II and stage III colon cancer after curative resection. But, the prognostic factor or predictive marker for the efficacy of FOLFOX remains unclear. This study was aimed to identify the prognostic value and cumulative impact of adjuvant FOLFOX on the stage II and III colon cancer patients.. A total of 196 stage II and III colon cancer patients were retrospectively enrolled in prospectively collected data. They underwent curative resection followed by FOLFOX4 adjuvant chemotherapy. The oncological outcomes included the 5-year disease-free survival (DFS) rate and 5-year overall survival (OS) rate. Cox-regression analysis was performed to identify the prognostic value, and its cumulative impact was analyzed.. The 5-year DFS rate of the patients was 71.94% and the 5-year OS rate was 81.5%. The prognostic values for the 5-year DFS rate and 5-year OS rate were T4 stage and preoperative anemia in a multivariate analysis. Each patient group who had no prognostic value, single, or both factors revealed 95.35%, 69.06%, and 28.57% in the 5-year DFS rate, respectively (p < 0.0001). The 5-year OS rate also showed the significant differences in each group who had no prognostic value, single, or both factors revealed 100%, 79.3%, and 45.92%, respectively (p < 0.0001).. Our results showed similar efficacy to MOSAIC study in stage II and stage III colon cancer patients treated with adjuvant FOLFOX chemotherapy after curative resection. Patients who had T4 stage and/or preoperative anemia showed worse prognosis than patients without any prognostic value. These findings suggest that FOLFOX could not be effective in the patients with T4 stage colon cancer accompanied by preoperative anemia.

Spinal metastases are the most common of spinal neoplasms and occur predominantly in an extradural location. Their appearance in an intradural location is uncommon and is associated with a poor prognosis. Cerebrospinal fluid dissemination accounts for a significant number of intradural spinal metastases mostly manifesting as leptomeningeal carcinomatoses or drop metastases from intracranial tumors. The occurrence of local tumor dissemination intradurally following surgery for an extradural spinal metastasis has not been reported previously. The authors describe 2 cases in which local intradural and intramedullary tumor recurrences occurred following resection of extradural metastases that were complicated by unintended durotomy. To heighten clinical awareness of this unusual form of local tumor recurrence, the authors discuss the possible etiology and clinical consequences of this entity.

We retrospectively analyzed the feasibility and adverse events for two regimens, postoperative chemoradiation (CRT) with 5-fluorouracil/leucovorin (5-FU/LV) compared to S-1 in D2-resected gastric cancer patients.. The study included 405 gastric cancer patients who underwent curative gastrectomy with D2 lymph node dissection and received adjuvant therapy between January 2008 and July 2009. Feasibility and adverse events for the CRT and S-1 regimens were analyzed.. Out of the 405 patients, 244 (60.2%) had CRT and 161 (39.8%) had S-1 treatment. The regimen was selected based on the preferences of the physician and the patient. S-1 was more frequently administered to patients with older age (age≥70) and those with early-stage disease (stage II). The stage was significantly more advanced in the CRT group compared to the S-1 group (S-1 vs. CRT: stage II, 59.6% vs. 36.1%; stage III/IV, 28.0% vs. 48.3%, respectively; p<0.001). The completion rate of the planned therapy was significantly higher in the CRT group than in the S-1 group (95.1% vs. 72.8%, respectively; p<0.001). Regarding severe adverse events (grade 3-4), neutropenia (CRT vs. S-1; 40.2% vs. 8.7%, respectively, p<0.001), nausea (CRT vs. S-1; 5.7% vs. 0%, respectively; p=0.002) and stomatitis (CRT vs. S-1; 7.4% vs. 2.5%, respectively; p=0.034) were significantly more frequent in the CRT cohort compared to the S-1 group.. Both adjuvant CRT with 5-FU/LV and adjuvant S-1 are safe and feasible in D2-resected gastric cancer patients. Patients with old age or early stage disease tend to prefer S-1 therapy to chemoradiation.

Colorectal cancer associated with Crohn's disease (CD) is increasing in proportion to the number of patients with CD in Japan. There are two subtypes of colorectal cancer with CD: sporadic cancer and colitis-associated cancer. Early diagnosis of colitis-associated cancer is sometimes difficult; when colorectal cancer is found in patients with CD, both colitis-associated cancer and sporadic cancer should be kept in mind. Here, we describe a case of metachronous, colitis-associated rectal cancer that developed after the complete resection of an adenoma that became a sporadic adenocarcinoma in a patient with longstanding CD. To the best of our knowledge, this is the first report of colitis-associated cancer in a patient with CD after removal of a sporadic cancer.. We describe a 51-year old man with CD who had difficulty in defecation. A rectal polyp was detected and a transanal resection of the polyp was performed. A histopathological examination showed an adenoma with sporadic adenocarcinoma. After three years, a follow-up colonoscopy revealed a reddish, elevated lesion in the patient's rectum. A colonoscopic biopsy showed a signet ring cell carcinoma. We performed an abdominoperineal resection of the rectum and a bilateral pelvic lymph node dissection. A histopathological examination revealed a mucinous adenocarcinoma with signet ring cell carcinoma and lymph node metastasis. The patient received adjuvant chemotherapy with oral uracil 224 mg combined with tegafur 100 mg plus leucovorin. No signs of recurrence were noted at a follow-up 18 months after the third surgery and 60 months after the second surgery.

To explore the impact of clinicopathological features and extent of lymph node dissection on the prognosis in early gastric cancer (EGC) patients.. A total of 142 EGC cases screened from database of gastric cancer of Sun Yat-sen University, from Aug. 1994 to Jan. 2010, were included in this study. According to the lymph node metastasis status, they were divided into lymph node negative (n = 116) and lymph node positive (n = 26) groups. The clinicopathological features of the two groups and the impact of extent of lymph node dissection on the prognosis were analyzed.. There were no significant differences in age, gender, tumor size and location, Borrmann typing, WHO TNM staging, histological typing, and CEA value between the two groups (P > 0.05). The TNM stages in the lymph node positive group were higher than that in the lymph node negative group (P < 0.001). Between the cases who underwent D1 (n = 21) and D2 (n = 121) dissection, there were no significant differences in postoperative hospital days, blood transfusion volume, and operation time (P > 0.05). The median numbers of LN dissected in D1 and D2 cases were 4 (0 to 16) and 20 (12 to 30), with a significant difference (P = 0.000), but the number of positive LN without significant difference (P = 0.502). The postoperative complication rates were 9.5% in the D1 and 3.3% in the D2 dissection groups, without a significant difference (P = 0.128). The median survival time of the lymph node negative and positive groups was 156 vs. 96 months (P = 0.010). In cases who received D2 and D1 lymph node dissection, the median survival time (MST) was 156 vs. 96 months (P = 0.0022). In the lymph node positive group, D2 dissection prolonged survival time significantly than D1 dissection (96 vs. 27months) (P = 0.001). Cox regression analysis showed that the extent of lymph node dissection and LN metastasis were independent prognostic factors for EGC patients.. It is not able to accurately assess the LN metastasis status preoperatively according to the routine clinicopathological features. For the patients with unknown LN metastasis status, D2 dissection should be the first choice. Comparing with D1 dissection, the morbidity of D2 dissection are not increased, but survival time is prolonged.

The aim of this study was to evaluate the activity and safety of the combination chemotherapy of 5-fluorouracil (5-FU), leucovorin, and irinotecan (FOLFIRI regimen) after failure of fluoropyrimidine, platinum, and taxane in gastric cancer (GC) and to evaluate the prognostic factors for survival.. Patients received biweekly FOLFIRI chemotherapy as third-line treatment. The FOLFIRI-1 consisted of irinotecan (180 mg/m(2) in a 2-h infusion) on day 1, and then leucovorin (200 mg/m(2) in a 2-h infusion) and 5-FU (a 400 mg/m(2) bolus, followed by 600 mg/m(2) in a 22-h continuous infusion) on days 1 and 2. FOLFIRI-2 consisted of irinotecan (180 mg/m(2) in a 2-h infusion) on day 1, and then leucovorin (400 mg/m(2) in a 2-h infusion) and 5-FU (a 400 mg/m(2) bolus, followed by 2400 mg/m(2) in a 46-h continuous infusion) on day 1.. A total of 158 patients were included. The overall response rate was 9.6 % in patients with measurable lesions. The median progression-free survival (PFS) and overall survival (OS) were 2.1 months [95 % confidence interval (CI), 1.7-2.5] and 5.6 months (95 % CI, 4.7-6.5), respectively. The major grade 3/4 toxicity was myelosuppression (36.7 %). Good performance status (PS), fewer metastatic sites, and longer duration from the first-line to third-line chemotherapy were independent prognostic factors affecting both PFS and OS.. The FOLFIRI regimen showed antitumor activity and tolerable toxicity profiles against advanced GC in the third-line setting. Patients with good PS, fewer metastatic sites and longer previous treatment duration might have the maximal benefit from third-line chemotherapy.

We report the case of a 62-year-old woman with a metastatic gastric cancer complicated by diffuse bone marrow carcinomatosis, disseminated intravascular coagulation (DIC) and microangiopathic hemolytic anemia (MHA) treated by modified FOLFOX-6 as front-line chemotherapy regimen. This chemotherapy showed clinical, morphological and biological efficiency and safety in this rare and severe hematological complication at initial diagnosis. Furthermore, this is the first case of diffuse bone carcinomatosis from a gastric cancer to be monitored by positron emission tomography integrated computed tomography (PET-CT) scan using 18-fluorodeoxyglucose (18-FDG).

A 16-year-old girl presented to our unit with crampy abdominal pain, change in bowel habit, a subjective impression of weight loss and a single episode of haematochezia. She was found to have a rectosigmoid adenocarcinoma and proceeded to laparoscopic anterior resection, whereupon peritoneal metastases were discovered. She received chemotherapy and is alive and well ten month later with no radiological evidence of disease. Colorectal carcinoma is rare in the paediatric population but is increasing in incidence. Early diagnosis is critical to enable optimal outcomes.

In some studies, the prognostic and predictive significance of M30 and M65 has been reported to detect response to chemotherapy. In the present study, we aimed at determining the changes of serum M30 and M65 values after chemotherapy and the impact of these values on treatment response and progression-free survival (PFS) and overall survival (OS) of patients with advanced gastric cancer. A total of 31 patients with advanced gastric cancer was included. M30 and M65 values were measured by a quantitative enzyme-linked immunosorbent assay (ELISA) method in serum samples before and 48 h after the first chemotherapy cycle. Pre- and postchemotherapy values of M30 and M65 were compared. The difference between the mean values of serum M30 and M65 before and after chemotherapy was calculated and the prognostic significance of changes for survival was evaluated by univariate and multivariate analysis. Logistic regression analysis was performed to predict response to chemotherapy. Serum M30 and M65 levels were found to be increased significantly after chemotherapy (M30, 582.7 ± 111.5 U/l [pre mean] vs. 983.3 ± 214.1 U/l [post mean], p = 0.01; M65, 2,061.7 ± 431.2 U/l [pre mean] vs. 2,646.3 ± 433.1 U/l [post mean], p = 0.003). Means of the differences of M30 and M65 levels before and 48 h after chemotherapy were 400.5 ± 190 U/l ([M30-difference] M30-D) and 584.6 ± 335.4 U/l (M65-D), respectively. Patients with serum M30-D of <400.5 U/l had better median PFS and OS times than patients with M30-D >400.5 U/l (PFS, 9.9 vs. 4.3 months, p = 0.018 and OS, 13.6 vs. 8.1 months, p = 0.029). In addition, median PFS and OS intervals in patients with serum M65-D > 584.6 U/l were significantly worse than those of patients whose M65-D was lower than or equal to 584.6 U/l (4.1 vs. 11.4 months for PFS, p = 0.002 and 5.7 vs. 13.6 months for OS, p = 0.005). Patients with values above M30-D and M65-D had a better tumor response compared with patients with values below M30-D and M65-D (p = 0.02 and p = 0.006, respectively). In the logistic regression analysis, only M65-D was significantly found to be an independent factor in predicting response to chemotherapy (p = 0.018, OR:1.4). However, only M30 levels after chemotherapy were found to be an independent prognostic factor for PFS in the multivariate analysis. These results showed for the first time that both M30 and M65 in serum samples of patients with advanced gastric cancer were elevated 48 h after chemotherapy and these were poor pr

Thrombotic microangiopathy occurs in 5-10% of patients with mucin-producing disseminated adenocarcinoma. A 28-year-old woman complained of fatigue, bone pain, and weight loss. There were pallor, icterus, and tenderness in the bones on physical examination. Microangiopathic hemolytic anemia, leukoerythroblastic picture, thrombocytopenia, and normal coagulation tests were detected. Thrombotic thrombocytopenic purpura (TTP) was diagnosed and therapeutic plasma exchange was performed on the patient. On day 5 a laparotomy had to be performed because of acute abdomen due to the rupture of a corpus hemorrhagicum follicle of an ovary. Signet ring cell adenocarcinoma stained with cytokeratin 7 and mucicarmine was seen on ovaries and bone marrow, after the pathological examination. The primary site of tumor could not be investigated, because of the patient's refusal. Although chemotherapy including cis-platinum, infusional 5-fluorouracil, and calcium leucovorin were administered in two courses, she died from respiratory failure. In conclusion, malignancy and bone marrow involvement should be considered when associated with leukoerythroblastic picture and TTP.

Signet ring carcinoma (SRC) of the appendix consists one of the most biologically virulent cancers. We present the case of a patient with primary SRC complicated by the development of acute inflammation of the appendix.. A 78-year-old man was admitted due to a 5-day history of increasing colicky abdominal pain and vomiting. Clinical examination revealed a firm, tender mass in the right ileac fossa. Laparotomy confirmed a tumor mass which appeared to originate from the appendix. The affected part of the bowel was resected and a right hemicolectomy with an end-to-side ileotransverse anastomosis was performed. The appendix was notably thickened with an ulcerated wall containing sinus tracts, chronic inflammation, and scarring. Moreover, a focus of SRC was detected.. Appendiceal SRC is a rare entity, which may sometimes be confused with other pathologies providing difficulties in differential diagnosis, having an impact on therapeutic decisions and affecting prognosis.

This report presents a rare patient with cardiac tamponade as the first manifestation of primary gastric signet-ring cell carcinoma.. A 56-year-old woman with emergent dyspnea, anterior chest oppression, and hypotension was diagnosed as having cardiac tamponade due to massive pericardial effusion. The endoscopic examination of the stomach disclosed gastric cancer in the posterior wall of the antrum and the biopsy showed signet-ring cell carcinoma. The gastric cancer was complicated by malignant pericardial effusion and pleural effusion as well as metastasis to the peripheral lymph nodes and bones. The patient was treated with percutaneous pericardiocentesis followed by systemic chemotherapy (oxaliplatin and sequential 5-fluorouracil plus leucovorin). The pericardial effusion gradually disappeared and there was no cardiac tamponade occurrence. The patient has survived more than 6 months so far.. Cardiac tamponade may originate from a primary gastric signet-ring cell carcinoma. Pericardiocentesis followed by systemic chemotherapy may be effective in controlling such advanced gastric signet-ring cell carcinoma.

Adjuvant chemotherapy has become a standard postoperative treatment for stage III and high risk stage II colorectal carcinoma patients. However, only a few patients can finish 6-month adjuvant chemotherapy. This study was to find out whether the duration of adjuvant chemotherapy would affect the 3-year disease-free survival.. Clinical data of 276 colorectal carcinoma patients, receiving at least two cycles of adjuvant chemotherapy including xeloda, 5-fluorouracil/calcium folinate (5-FU/CF) or Tegafur with or without oxaliplatin after radical operation in Sun Yat-sen University Cancer Center from April, 2003 to December, 2007, were analyzed for the impact of adjuvant chemotherapy duration on the 3-year disease-free survival.. Of the 276 patients, 216 received chemotherapy including oxaliplatin, 60 received xeloda, 5-FU/CF or tegafur as adjuvant chemotherapy. Of the 216 patients, only 49 finished the 6-month adjuvant chemotherapy. Both univariate and multivariate analyses showed that chemotherapy duration (P=0.032), sex (P=0.001), N stage (P=0.002), and pathologic differentiation (P=0.043) were independent prognosis factors for 3-year disease-free survival.. Duration of adjuvant chemotherapy is an independent prognosis factor for 3-year disease-free survival of colorectal carcinoma patients.

We describe our experience with a patient who had unresectable anal signet-ring cell carcinoma with extensive metastases to the lymph nodes, lungs, and bones. The patient was treated with bevacizumab (Bev)+mFOLFOX6 and achieved complete response (CR). He was a man in his fifties, who visited a local doctor with the chief complaints of swelling in the axillary and inguinal regions. Signet-ring cell carcinoma was diagnosed by examination of a biopsy specimen from the inguinal lymph nodes. A search for the primary tumor was performed, and anal canal carcinoma with pagetoid spread was detected in the perianal region. Positron emission tomography-computed tomography (PET-CT) showed an accumulation in lymph nodes throughout the body, as well as in the lungs and the bones. Bev+mFOLFOX6 therapy was initiated. After completion of 4 courses, the lymph nodes were no longer palpable. PET-CT scanning showed no accumulation. During the 8th course, tumor markers decreased to the normal range, and CR was diagnosed. When 13 courses had been completed, the patient experienced grade 3 numbness of the hands and feet, so his treatment was changed to Bev+FOLFIRI therapy. In conclusion, Bev+mFOLFOX6 therapy achieved 6 months of CR in our patient who had anal signet-ring cell carcinoma with systemic metastases, which seemed likely to have a very poor prognosis.

There are different types of skin changes associated with internal malignancy. One type is the skin involvement as a result of cutaneous metastasis from an internal tumor. The skin is an uncommon site for distant metastasis; when it is present the most common sources are breast, lung, and colon. Metastasis generally occurs after an internal malignancy had been discovered and signifies disseminated disease with a poor prognosis. We report an exuberant and rare case of cutaneous metastasis from gastric adenocarcinoma as the first sign of this serious visceral cancer.

A 67-year-old woman with a history of smoking presented with abdominal pain and hematuria. On physical examination, she had a palpable pelvic mass. Imaging revealed a large pelvic mass situated on the dome of the bladder, extending from the urachus, without evidence of other sites of metastases. After resection, urachal adenocarcinoma was histologically confirmed. No adjuvant therapy was administered. Repeat imaging obtained 3 months after resection revealed a large left pelvic mass consistent with recurrence.. Physical examination, pelvic and complete lymph-node examination, laboratory tests, urine analysis, CT scan of the abdomen and pelvis, chest X-ray, bone scan, cystoscopy, histologic examination of tumor morphology, and MRI of the abdomen and pelvis.. Metastatic urachal adenocarcinoma.. Surgical excision combined with cystectomy and pelvic lympadenectomy, chemotherapy with 5-fluorouracil, leucovorin, and irinotecan.

We describe our experience with a patient who had undifferentiated gastric carcinoma with extensive lymph node metastasis, including para-aortic lymph-node metastasis, and had a complete response to induction therapy with methotrexate plus 5-fluorouracil (sequential therapy with MTX, 5-FU, and Leucovorin) and secondary treatment with oral TS-1. The patient was a 71-year-old woman with a massive gastric tumor (signet ring cell carcinoma), occupying most of the stomach. A computed tomographic (CT) scan revealed para-aortic, celiac, and common hepatic lymph-node metastases. Stage IV disease was diagnosed. Palliative total gastrectomy was performed to control bleeding and to improve oral intake of food. Two courses of induction therapy with MTX, 5-FU, and Leucovorin were started 3 weeks after surgery. A CT scan revealed residual lymph node metastasis. The response was assessed to be no change, but the levels of carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 improved from 7,028 ng/ml and 726 U/ml 3 weeks after surgery to 2,832 ng/ml and 281 U/ml, respectively. Secondary treatment with oral TS-1 was begun, and a CT scan showed distinct shrinkage of lymph-node metastases. There was no serious toxicity. The levels of CEA and CA19-9 decreased markedly to 2.9 ng/ml and 16 U/ml, respectively, about 6 months after surgery and remained at 3.7 ng/ml and 16 U/ml, respectively, about 1 year after surgery.

Gastric adenocarcinoma is a high-lethality tumour and has a great tendency to recur. Liver and peritoneum are the places where the metastases are most frequently localised. We introduce the case of a woman diagnosed with gastric adenocarcinoma who showed isolated skin metastasis. There were an important number of recurrences (always in the skin). She was treated with radical surgery and later treated with different cytostatic schedules. The patient died 13 years after metastasis were diagnosed. With this case we wanted to pay attention to the role of the biologic prognostic factors of gastric carcinoma. The molecular biology of these tumours can explain the different evolution of the disease. Biologic prognostic factors can separate gastric carcinoma into different kinds of disease.

A 49-year-old man was hospitalized because of a 2-month history of purpura in his extremities and for back pain. Laboratory findings showed alkaline phosphatase to be greatly elevated, and platelet counts and coagulation factor showed that the patient had disseminated intravascular coagulation (DIC). Compression fractures of the thoracic vertebrae were found on radiological examination. The histological findings from bone marrow showed metastasis of adenocarcinoma with signet-ring cells, although the primary site was unknown. To reduce tumor cells in number and improve DIC, 11 cycles of 5-Fluorouracil and leucovorin therapy were done, and the patient survived for 12 months. Autopsy showed a 0.8 cm diameter, poorly differentiated adenocarcinoma with the signet-ring cell type in the lamina propria of the Vater's ampulla. Many metastatic foci and micro tumor emboli were found in the lung and in bone marrow. The sections of the stomach, the gallbladder, urinary bladder, prostate, and thyroid gland showed no malignant cells. These findings suggest that the origin of the cancer may have been located in the Vater's ampulla. This is a rare case of an ampullary tumor of poorly differentiated adenocarcinoma with the signet-ring cell type, without jaundice but with multiple metastasis. 5-Fluorouracil and leucovorin were effective for increasing survival time and improving quality of life.

We report a case in which weekly paclitaxel (TXL) administration was effective for gastric cancer with malignant ascites. TXL (80 mg/m2) was infused over 1 hour after short premedication on an outpatient basis. Administration was continued for 3 weeks followed by 1 week rest. The patient was a 49-year-old woman who suffered from non-resectable gastric cancer, staged intraoperatively as having severe lymph node metastasis and malignant ascites. As an outpatient treatment, she was first treated with 5-fluorouracil combined with high-dose Leucovorin for 4 cycles. However, she complained of abdominal fullness and ascites, and received weekly TXL administration as the second line treatment. The ascites had completely disappeared 3 months after administration. The toxic events were anemia (grade 1) and alopecia (grade 2). No major adverse effects such as hypersensitivity reaction, leukopenia or peripheral neuropathy were observed.

The detection of gastrointestinal signet-ring cell carcinoma by endoscopy can be a diagnostic challenge. The main clinical features include atypical metastasis and a poor prognosis. We present a case of a metastasizing signet-ring cell carcinoma with unknown primary location arising in 71-year-old female. Following 6 cycles of a routine intravenous FU/FA chemotherapy, an almost complete remission could be observed. After 2 years of follow up, metastatic recurrence was detected to the lower back musculature. This case report emphasizes the difficulties in diagnosing signet-ring cell carcinoma by endoscopy and demonstrates an unusual clinical course.

Recently, as society ages there have become more elderly gastric cancer patients with/without several complications(cerebrovascular diseases, cardiac diseases, atherosclerosis, DM, etc.), that were non-resected and require highly effective chemotherapy and good QOL. We report two elderly gastric cancer patients responding to chronomodulation chemotherapy (tegafur + cisplatin + Isovorin) based on circadian rhythms plus a new antitumor drug, S-1. The treatment protocol was tegafur 800 mg/body, days 1-7 (continuing 16 h, intravenously with 500 mg/body from 16 to 0 h, 300 mg/body from 0-8 h, for non-uniform administration), cisplatin 10 mg/body, days 1-5, (16 h), Isovorin 25 mg/body, days 1-5, (16 h, oneshot infusion, for 4 courses followed by a week rest. Next was S-1 120 mg/body x 2 times orally for 28 days, followed by 2 weeks rest, the administered for another 28 days. The first patient was 74 years of age, with advanced type 3 plus early type IIc gastric cancers with liver metastasis (H1). After chemotherapy the liver metastasis disappeared, there was a 70% reduction in the advanced cancer and the early cancer disappeared. The second patient was 84 years of age, with advanced type 3 gastric cancer invading the esophagus. After chemotherapy, the primary lesion was reduced 80% and the esophageal invasion mass shrunk. The only adverse effect was grade 2 pancytopenia. In conclusion this regimen resulted in good intrachemotherapeutic QOL and highly effective performance in elderly advanced gastric cancer patient.

Ovarian metastasis may present at the time of initial diagnosis of colon carcinoma or as a later recurrence. Little meaningful information is available regarding the treatment and outcome of synchronous ovarian metastasis of colon carcinoma. This report describes the clinical course of five patients with synchronous ovarian metastasis of colon carcinoma who were treated with aggressive surgery and chemotherapy. The treatment consisted of maximal surgical debulking followed by systemic chemotherapy with weekly 24 h infusion of high-dose 5-fluorouracil and leucovorin. All of the five patients had subsequent disease-free periods ranging from 6 to 43+ months following operation. Two of the patients who had no or minimal peritoneal involvement were still alive without disease at 33 and 43 months. The data from these cases suggest that aggressive surgery and systemic chemotherapy may be highly efficacious in the treatment of colon carcinoma with synchronous ovarian metastasis. Maximal debulking followed by chemotherapy may be particularly effective in those patients with minimal peritoneal involvement.

Microangiopathic hemolytic anemia (MAHA) and disseminated intravasal coagulation (DIC) as initial paraneoplastic symptoms of a solid tumor present a rare clinical situation.. In 1998 a female patient was admitted due to multiple thrombosis, thrombocytopenia and fever. The initial diagnostic procedures revealed peri-aortic lymphomas and a tumor bulk (7 x 8 cm) in the upper abdomen. Gastroscopy revealed a 2 cm ulcer at the back side of the gastric corpus. Histologically, a signet-ring cell carcinoma was diagnosed. Final diagnosis stated a multilocular metastasising gastric cancer with infiltration of bone, peritoneum and dura and signet-cell infiltration of the bone marrow. Hematologic investigation in view of multiple paraneoplastic thrombosis revealed a microangiopathic hemolytic anemia associated with disseminated intravasal coagulation. Parallel to initial symptomatic therapy of coagulopathy, systemic cytostatic therapy with CDDP and VP-16 was initiated. In addition, radiotherapy of the brain was performed. After histologic confirmation of the diagnosis, weekly therapy with 5-FU (2600 mg/m2) and folinic acid (500 mg/m2) according to the Ardalan protocol was performed. After first signs of moderate response, oxaliplatin (60 mg/m2, day 1) was added. Although the chemotherapy dose had to be reduced due to prolonged neutropenia, the disturbances of hemostasis resolved completely resulting in reduced substitution rates with fresh frozen plasma (FFP) and platelets. Unfortunately, the patient died at home due to pulmonary embolism.. Tumor-associated hemostaseologic alteration requires immediate substitution of FFP and platelets. However, it should be followed by specific therapy of malignancy, since tumor-induced metabolites (e.g. mucin) maintain the alteration of hemostasis. Chemotherapy may therefore be the best strategy to prevent complications such as MAHA and DIC.

A 73-year-old woman was admitted to our hospital in June 1998, suffering from upper abdominal pain. The upper G-I series and endoscopic examination revealed stenosis of the pylorus and antrum by a type 2 cancer, and a poorly differentiated adenocarcinoma and a signet-ring cell carcinoma were confirmed on endoscopic biopsy. A CT scan showed the enlargement of many regional and abdominal para-aortic lymph nodes. FLP therapy combined with cisplatin (50 mg/m2 drip i.v., day 1-8), 5-fluorouracil (333 mg/m2 drip i.v.) and leucovorin (30 mg/body i.v., day 1-8) was planned for neoadjuvant chemotherapy (NAC) in order to reduce or eliminate the tumor and increase curability. After two cycles of the FLP therapy, the tumor size shrunk remarkably and the enlargement of the para-aortic lymph nodes disappeared. Distal gastrectomy with extended lymphadenectomy and cholecystectomy was performed. The histological findings of the primary tumor and metastatic lymph nodes demonstrated massive cancer cell degeneration such as pycnosis and vacuolation, xanthogranulomatous inflammation and dense fibrosis. The effect of NAC was judged to be grade 2 histologically. FLP therapy is an effective and safe regimen for NAC.

A 65-year-old man complaining of nausea and loss of appetite was diagnosed as having Borrmann type 3 gastric cancer with multiple liver metastasis. He was treated for 5 days with bolus injections of l-leucovorin (l-LV: 100 mg/m2/day) followed by 5-fluorouracil (5-FU; 370 mg/m2/day), and this was repeated every 4 weeks. The computed tomography scan after 3 cycles showed an approximately 70% decrease in the size of metastatic lesions, indicating a partial response. The primary gastric lesion also showed a partial response. There were modest but tolerable side effects such as diarrhea. After 3 cycles, the patient was discharged and was given oral 5-FU preparation. He died 9 months after initial chemotherapy with a response duration of 5 months. This l-LV and 5-FU combination therapy appears useful for advanced gastric cancer.
