s-1-(combination) and lafutidine

The present study evaluated the efficacy of lafutidine, a histamine H2 receptor antagonist, for reducing gastrointestinal toxicities during adjuvant chemotherapy using oral fluorouracil anticancer drugs for gastric cancer.. Patients with stage II (T1 cases excluded) or stage III gastric adenocarcinoma who underwent gastrectomy with D2 lymphadenectomy achieving R0 resection from 2011 to 2013 were prospectively enrolled in the study. Patients were randomly assigned to either S-1 treatment or S-1 plus lafutidine treatment. Quality of life and gastrointestinal toxicity were evaluated before chemotherapy and at 2, 4, and 6 weeks after the beginning of treatment.. The incidence of diarrhea during chemotherapy was significantly lower in the S-1 plus lafutidine group than in the group treated with S-1 alone (10% vs. 83%, respectively; p=0.002). The grades of diarrhea and nausea during chemotherapy were also significantly lower compared to those before chemotherapy in patients receiving S-1 plus lafutidine than in those administered S-1 alone. The rate of patients requiring a dose reduction or interruption of S-1 was significantly lower in the S-1 plus lafutidine group than in the group treated with S-1 alone (30% vs. 83%, respectively; p=0.027).. Lafutidine might be useful not only for preventing gastrointestinal toxicities during adjuvant chemotherapy for gastric cancer, but also for improving compliance with taking oral fluorouracil anticancer drugs. However, this indication needs to be confirmed in a larger, prospective, randomized, controlled trial.

This study evaluated the utility of the histamine H2-receptor antagonist lafutidine in patients taking oral fluorouracil (S-1) for head and neck squamous cell carcinoma (HNSCC), by comparing patients with and without concomitant lafutidine.. Study subjects comprised 63 patients who received adjuvant S-1 following curative resection of HNSCC at our institutions between August 1, 2013 and December 31, 2019. The primary endpoint was the completion rate of S-1 therapy.. For the lafutidine-treated group, the median completion rate was significantly greater (94.4% vs. 24.6%, p=0.01), and progression-free and overall survival were both significantly prolonged compared to the non-lafutidine group. In terms of adverse events, the incidence of diarrhoea was significantly reduced (p<0.00189) in the lafutidine-treated group.. Taking lafutidine during S-1 treatment appeared to reduce gastrointestinal disturbance and increased the S-1 completion rate, improving both progression-free and overall survival as a result.
