s-1-(combination) and Feeding-and-Eating-Disorders

Unresectable advanced hepatocellular carcinoma is a heterogeneous disease, for which sorafenib is the first targeted agent approved for first-line therapy, and treatment options for patients with sorafenib-refractory advanced hepatocellular carcinoma are limited. We assessed the efficacy and safety of S-1, a chemotherapeutic agent based on fluorouracil, in patients with sorafenib-refractory advanced hepatocellular carcinoma.. We did a randomised, double-blind, placebo-controlled, phase 3 study done at 57 sites in Japan. Patients with advanced hepatocellular carcinoma who were ineligible for surgical or local-regional therapy and judged refractory to sorafenib (ie, had progressed on sorafenib or had discontinued sorafenib because of adverse events) were randomly assigned (2:1) to receive oral S-1 (weight-banded 80 mg/m. Between Oct 26, 2009, and Aug 22, 2012, we screened 399 patients. 65 patients were excluded due to not meeting criteria (n=61), declining to participate (n=3), or other reasons (n=1). 334 patients were randomly assigned to receive either S-1 (n=223) or placebo (n=111). One patient in the S-1 group did not receive treatment, and was thus excluded from analyses. At data cutoff, median follow-up was 32·4 months (IQR 24·0-34·7) in the S-1 group and 32·9 months (23·7-39·5) in the placebo group. Median overall survival was 11·1 months (95% CI 9·7-13·1) in the S-1 group and 11·2 months (9·2-12·8) in the placebo group (hazard ratio 0·86, 95% CI 0·67-1·10; p=0·220). The most frequently reported adverse events were skin hyperpigmentation (123 [55%] of 222 patients in the S-1 group vs nine [8%] of 111 patients in the placebo group), decreased appetite (104 [47%] vs 21 [19%]), fatigue (102 [46%] vs 20 [18%]), diarrhoea (77 [35%] vs 14 [13%]), and increased blood bilirubin (77 [35%] vs 14 [13%]). Serious adverse events were reported in 90 (41%) of 222 patients in the S-1 group and 24 (22%) of 111 patients in the placebo group. Five treatment-related deaths were reported in the S-1 group.. S-1 did not prolong overall survival in patients with sorafenib-refractory advanced hepatocellular carcinoma. Further research is needed to identify subgroups of patients who might benefit from S-1..

Although leucovorin enhances the efficacy of fluorouracil, the anti-tumour activity of S-1 and leucovorin and their combination with oxaliplatin for patients with advanced gastric cancer is unknown. We compared the activity and safety of S-1 plus leucovorin, S-1 plus leucovorin and oxaliplatin, and S-1 plus cisplatin as first-line chemotherapy for advanced gastric cancer.. In this multicentre, randomised, open-label, phase 2 trial, we recruited chemotherapy-naive patients with unresectable or recurrent gastric cancer with measurable lesions aged 20 years or older from 25 general hospitals and specialist centres in Japan. Patients were randomly assigned (1:1:1) centrally to receive S-1 plus leucovorin (S-1 40-60 mg orally plus oral leucovorin 25 mg twice a day for 1 week, every 2 weeks), S-1 plus leucovorin and oxaliplatin (S-1 plus leucovorin and intravenous oxaliplatin 85 mg/m(2) on day 1, every 2 weeks), or S-1 plus cisplatin (S-1 40-60 mg orally twice a day for 3 weeks, plus intravenous cisplatin 60 mg/m(2) on day 8, every 5 weeks). Randomisation was done with the minimisation method using performance status (0 vs 1) and tumour stage (stage IV vs recurrent) as stratification factors. The primary endpoint was independently reviewed overall response in the full analysis set. This trial is registered with Japic CTI, number 111635.. Between Oct 20, 2011, and Dec 17, 2012, we enrolled and randomly assigned 145 patients: 49 patients were assigned to S-1 plus leucovorin, 47 to S-1 plus leucovorin and oxaliplatin, and 49 to S-1 plus cisplatin. An objective response assessed by the independent review committee was achieved in 20 (43% [95% CI 28·3-57·8]) of the 47 patients in the S-1 plus leucovorin group, 31 (66% [50·7-79·1]) of the 47 patients in the S-1 plus leucovorin and oxaliplatin group, and 22 (46% [31·4-60·8]) of the 48 patients in the S-1 plus cisplatin group (Fisher's exact test, p=0·84 for S-1 plus leucovorin vs S-1 plus cisplatin, p=0·063 for S-1 plus leucovorin and oxaliplatin vs S-1 plus cisplatin, and p=0·038 for S-1 plus leucovorin and oxaliplatin vs S-1 plus leucovorin). The most common grade 3-4 adverse events were neutropenia (three [6%] of 48 patients in the S-1 plus leucovorin group vs 12 [26%] of 47 patients in the S-1 plus leucovorin and oxaliplatin group vs 17 [35%] of 49 patients in the S-1 plus cisplatin group), decreased appetite (six [13%] vs 14 [30%] vs 12 [24%]), anaemia (five [10%] vs seven [15%] vs 13 [27%]), and hyponatraemia (two [4%] vs two [4%] vs nine [18%]).. S-1 plus leucovorin and oxaliplatin was more active than S-1 plus leucovorin or S-1 plus cisplatin with acceptable toxic effects for patients with advanced gastric cancer. A phase 3 trial comparing S-1 plus leucovorin and oxaliplatin with S-1 plus cisplatin is underway.. Taiho Pharmaceutical.
