The study is an open-label, single-arm, single-country and multi-center phase II investigator-initiated trial. Patients with locally advanced gastric or gastroesophageal junction adenocarcinoma who enroll the trial will receive perioperative chemotherapy with LOTS (14 days as a cycle) 4 cycles every 2 weeks, followed by operation and another 4 cycles every 2 weeks post-operatively. The primary outcome is pathological response or curative resection rate. The secondary outcome includes recurrence-free survival, overall survival, disease control rate, protocol completion rate and adverse events.
The aim of the trial is to investigate the clinical efficacy and toxicity of perioperative chemotherapy with leucovorin, oxaliplatin, docetaxel and S-1 (LOTS) in patients with locally advanced gastric or gastroesophageal junction adenocarcinoma who receive a curative surgery.
