s-1-(combination) and taxane

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.

To evaluate the effects of S-1, an orally administered 5-FU agent, versus taxane on patient-reported outcomes (PROs) in the SELECT BC trial.. Patients with HER2-negative and endocrine treatment-resistant breast cancer with metastasis or recurrence after surgery were randomly assigned to receive first-line taxane or S-1. PROs (secondary endpoint) were assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and Patient Neurotoxicity Questionnaire (PNQ) at baseline and at 3, 6, and 12 months. We conducted a responder analysis for the QLQ-C30 and PNQ and created cumulative distribution function (CDF) plots as a sensitivity analysis.. The questionnaire response rates were over 80% from 386 patients, who completed at least one baseline questionnaire. S-1 was significantly superior to taxane with respect to 6 scales (physical functioning [p = 0.03], role functioning [p = 0.04], social functioning [p < 0.01], financial difficulties [p = 0.01], global health status [p = 0.02], and constipation [p < 0.01]) and sensory neuropathy (p = 0.01). The CDF plots partially supported the conclusions and their robustness.. First-line S-1 therapy has clinical benefits with respect to many aspects of health-related quality of life for metastatic breast cancer patients.

While some studies show improved outcomes in clinical trial participants as compared to non-participants, existence of such a trial effect has not been proved precisely.. This was a prospective cohort study to compare the prognoses for participants in the randomized controlled trial (SELECT BC) and non-participants. SELECT BC compared S-1 and taxane as first-line treatment for metastatic breast cancer. Non-participants were all patients who met the eligibility criteria of SELECT BC and who had been requested to participate in that trial by attending doctors and declined. The study aimed to compare the prognoses between participants and non-participants. The primary endpoint was median overall survival.. The median OS in participants was significantly superior to that in non-participants with a statistically significant difference (36.8 months vs. 25.2 months. HR 1.48, p = 0.022). A similar result was obtained when only patients who received the same chemotherapy (S-1 or taxane) used in SELECT BC after declining participation were assumed as non-participants (36.8 months vs. 22.0 months. HR 2.03, p = 0.006).. This study may suggest the existence of a trial effect, in which, for a given treatment, participation in a clinical trial is associated with a better outcome.

Taxane monotherapy is widely used for advanced gastric cancer (AGC) after failure of standard first-line chemotherapy with fluoropyrimidine and cisplatin. Triplet chemotherapy with docetaxel, cisplatin, and S-1 (DCS) is a promising regimen for first-line chemotherapy of AGC. The aim of this study was to evaluate the efficacy of taxane monotherapy in patients refractory to DCS.. We retrospectively evaluated the efficacy and safety of taxane monotherapy in patients with AGC refractory to first-line therapy with DCS between January 2010 and April 2015. Selection criteria were as follows: ECOG PS of 0-2, treatment with taxane monotherapy in second-line or third-line therapy after failure of second-line irinotecan, absence of massive ascites, and adequate organ function.. A total of 30 patients were included in this study. Of these, 15 patients received paclitaxel while another 15 received nanoparticle albumin-bound paclitaxel in either second- or third-line treatment. Median age for the second/third-line group was 64.0/62.0 (range 27-75/42-75); 14/13 (93.3/86.7%) had ECOG PS of 0 or 1. No patients achieved complete or partial response and stable disease was observed in 37.5/35.7% of the patients in the second/third line. Median progression-free survival and overall survival were 3.4 and 5.8 months in the second-line group, and 2.0 and 4.5 months in the third-line group, respectively. The incidences of any grade ≥3 adverse events in the second-line group and the third-line group were 60.0 and 33.3%, respectively. There was no treatment-related death.. Taxane monotherapy after DCS failure had acceptable toxicities but was ineffective in AGC patients.

We assessed the impact of treatment preferences in second-line chemotherapy on breast cancer prognosis using the SELECT BC study.. The SELECT BC study was performed in patients with HER2-negative metastatic breast cancer treated with initial chemotherapy. From these patients, 618 were assigned to 2 groups (S-1 group, 309; taxane group, 309). The S-1 and taxane groups were each subdivided into 3 groups: crossover group, protocol-recommended group, and other group, and the analysis of overall survival (OS) was performed using Cox regression with inverse probability weighting, to adjust for postrandomization confounding.. In the taxane group, the OS of the crossover group (39.6 months) was better than that of the protocol-recommended group (35.7 months) and the other chemotherapy group (36.9 months) (vs. the protocol-recommended group, HR 0.72 [95% CI 0.52-0.98], p = 0.037; vs. the other chemotherapy group, HR 0.71 [95% CI 0.43-1.18], p = 0.183). In the S-1 group, there was no statistically significant difference in OS between the 3 groups.. The study of the combination of first-line chemotherapy and second-line chemotherapy showed that S-1 might be recommended as a second-line chemotherapy in patients in whom taxane was the primary chemotherapy.

It is not clear what the optimal treatment of chemotherapy is for patients with heavily treated metastatic breast cancer (MBC). We have retrospectively examined the efficacy and safety of S-1 in patients with MBC who had been previously treated with anthracycline, taxane, and capecitabine.. Patients with MBC who had been administered S-1, an oral modulated compound containing a fluoropyrimidine derivative, between November 2001 and June 2003 at the Cancer Institute Hospital were retrospectively reviewed. S-1 at a standard dose of 50 mg/body was administered twice daily for four weeks, followed by a two-week rest period. This was repeated every six weeks until disease progression or unacceptable toxicity.. Thirty-five patients were assessed. The patients were heavily pretreated with anthracycline (100%), taxane (paclitaxel or docetaxel) (100%), capecitabine (100%), vinorelbine (71%), and mitomycin (69%). Median follow-up time of patients was 9.6 months (range, 1.2-26.6). ORR was 3% (95% confidence interval: 0-9%), and CBR was 20% (95% confidence interval: 6-33%). Time to treatment failure was 2.8 months. Overall survival was 21.4 months. Grade 1 or 2 adverse events were observed in 17% and 13%, respectively. Grade 3 events occurred as anorexia (9%), nausea (9%), vomiting (9%), diarrhea (14%), fatigue (3%), and elevation of AST/ALT (3%). No grade 3 was seen as hand-foot syndrome. Neither grade 3 nor 4 was observed in bone marrow suppression.. S-1 was fairly well tolerated, but demonstrated very limited activity in capecitabine-pretreated patients who had already been exposed to anthracycline and taxane. It was suggested that S-1 clinically exhibited cross-resistance to capecitabine.

We experienced a case of recurrent breast cancer resistant to prior medications, which was treated with oral S-1, a fluoropyrimidine-class anticancer drug, and exhibited the marked shrinkage of liver metastasis. The prior treatments including anthracycline and taxane were judged not effective because of the progressive disease. Then the oral treatment with S-1 was started at 120 mg/day bid. targeting metastatic lesions of the liver. At the end of the second cycle,a significant improvement was noted with a decrease rate of 82.5%. The S-1 monotherapy was thus considered to be an effective treatment for advanced or recurrent breast cancer resistant to anthracyclines and taxanes.

We had 2 patients with marked shrinkage of liver metastasis by administration of the oral fluorinated pyrimidine anticancer drug S-1 for advanced/recurrent breast cancer that was resistant to taxane and another antitumor drugs. Both patients almost completed the full dose through the whole course of treatment,and the drug showed good tolerability. S-1 was considered to possess beneficial antitumor efficacy and tolerability and to be promising as home chemotherapy for advanced/recurrent breast cancer.

We had 3 patients with recurrent/advanced breast cancer in whom a notable reduction in the size of the targeted tumors was seen following administration of S-1 (TS-1), a new oral pyrimidine fluoride anticancer drug. All of the patients had received taxane and/or anthracycline anticancer drugs as prior therapy; however, they were judged to be non-responsive to the drugs. The size of the targeted tumor decreased to 55.7% after 3 courses of the therapy in Patient 1. The tumor disappeared at completion of the third course in Patient 2, although the therapy was temporarily suspended during the second course due to adverse drug reactions, and the therapy was then resumed after 2-week drug withdrawal. Patient 3 was able to undergo long-term therapy, consisting of 8 courses for 11 months, and the size of the tumor reduced to 58.1%. No serious adverse drug reactions to S-1 occurred in our 3 patients. It is thought that less toxicity enabled Patient 3 to undergo long-term therapy. We consider S-1 to be a useful anticancer drug for treatment of taxane and/or anthracycline resistant recurrent breast cancer.

Chemotherapy results for all 157 patients with advanced/recurrent gastric cancer at our institute were analyzed based on survival duration. The median survival time (MST) of all 157 patients was 426 days. The break down of the 157 patients are as follows: 59 patients with recurrence after curative operation, 47 patients with a radical grade C after non-curative operation and 51 patients with unresectable gastric cancer, and whose MST's were 590, 610 and 215 days, respectively. The standard chemotherapy for advanced/recurrent gastric cancer has not been established. Our data showed that chemotherapy for gastric cancer should be performed as a means of clinical study. If the patients had any exclusion criteria of clinical study or a proper clinical study did not exist, we would have recommended the TS-1 based regimen as the first-line chemotherapy, and the taxane based regimen as the second-line chemotherapy.

A patient with lung metastasis of breast cancer was reported. The patient underwent surgery in December, 1999. Her breast cancer then recurred in December, 2000. After treatment failure with anthracycline and taxane antitumor drugs,she participated in a phase II study of S-1, a fluorinated pyrimidine anticancer drug, which was given orally at 80 mg/m2/day (2 doses). After completion of 4 courses of treatment,the target lesions of the lung metastasis markedly shrunk by 47.5% as compared with the pretreatment. Because salvage therapy with S-1 alone showed good antitumor efficacy and beneficial tolerability when the standard dosage was maintained, it was considered that this home therapy was effective for advanced/recurrent breast cancer that was resistant to anthracycline and taxane antitumor drugs.

A second-line chemotherapy for advanced gastric cancer has not been established. We report a case of good response in a 39-year-old woman who had recurrent pleural effusion and positive cytology of type 4 gastric cancer and was treated with TS-1, a DPD inhibitory fluoropyrimidine, in combination with weekly taxane. After a partial response for type 4 gastric cancer from the treatment with 2 courses of TS-1 plus low-dose cisplatinum (CDDP), followed by outpatient chemotherapy with TS-1 alone or TS-1 plus weekly CDDP, left pleural effusion appeared and CA19-9 increased during the 7th course of the chemotherapy. Cytology of the effusion was class IV. The patient was treated with a course of TS-1 (120 mg/day, day 1-21) plus paclitaxel (50 mg/m2, day 1, 8) followed by 2 week washout. In the following courses, paclitaxel was replaced with docetaxel (30 mg/m2, day 1 and 8) and the course was continued in the outpatient setting. After 2 courses, the left pleural effusion disappeared and remained absent after 6 courses. Gastric biopsy showed no cancer cells and abdominal CT showed no recurrence. Serum CA19-9 doubled 1 week after taxane treatment and decreased gradually week by week during the course. This case suggests that a combination of TS-1 and taxane is effective against recurrent pleural effusion of advanced gastric cancer and useful as a second-line chemotherapy.
