NCT03399110

Brief Summary

Our study aims to compare the efficacy and safety of 4-month versus 6-month adjuvant chemotherapy with capecitabine and oxaliplatin following D2 gastrectomy in patients with gastric cancer. Hypothesis: In patients with gastric cancer who have undergone D2 gastrectomy, a 4-month regimen of capecitabine and oxaliplatin demonstrates noninferiority to a 6-month regimen in terms of disease-free survival (DFS) and safety.

EXPERIMENTAL

Adjuvant chemotherapy with capecitabine and oxaliplatin after surgery consists of 5 to 6 cycles, each lasting 3 weeks: oral capecitabine at 1000 mg/m² twice daily on days 1-14, combined with intravenous oxaliplatin at 130 mg/m² on day 1, administered for 5 to 6 months or until disease progression.

Drug: OxaliplatinDrug: Capecitabine

XELOX for 6 months
