Neoadjuvant Chemoradiotherapy vs. Chemotherapy Followed by Radical Gastrectomy and Adjuvant Chemotherapy for Advanced Gastric Cancer

Patients with histologically confirmed gastric adenocarcinoma with locally advanced gastric cancer are randomized in a 1:1 ratio to receive neoadjuvant chemoradiotherapy with DT45Gy/25f plus three cycles of XELOX therapy or neoadjuvant chemotherapy alone using XELOX regimen following D2 gastrectomy and adjuvant chemotherapy for 3 cycles. The primary end point is 3-year disease free survival (DFS), and secondary end point is 5-year overall survival (OS), R0 resection rate, pathological complete remission (pCR) and treatment safety.
