The study enrolls patients with extrahepatic cholangiocarcinoma or gallbladder carcinoma who have undergone curative resection and harbor high-risk recurrence factors, including: 1) narrow resection margin (including R1 resection); 2) positive circumferential resection margin; 3) T stage ≥ T3-4; 4）positive regional lymph nodes. All patients will receive postoperative concurrent chemoradiotherapy (CCRT) with intensity-modulated radiotherapy (IMRT) or volumetric modulated arc therapy (VMAT). The high-risk volumes of the primary tumor bed and metastatic lymph node beds will be irradiated to 48-60 Gy in 20-25 fractions. Retroperitoneal and intra-abdominal lymph nodes will receive 50-57.5 Gy in 20-25 fractions, and lymphatic drainage regions will be treated to 40-45 Gy in 20-25 fractions. During radiotherapy, concurrent oral capecitabine will be administered at a dose of 1,600 mg\u002Fm² on Days 1-14, every 21 days for 2 cycles. Following the completion of radiotherapy, maintenance oral capecitabine will be continued at 2,000 mg\u002Fm² on Days 1-14, every 21 days for 6 cycles. For patients intolerant to capecitabine, S-1 will be substituted: concurrent S-1 40-50 mg twice daily on Days 1-28, every 42 days for 1 cycle, followed by maintenance S-1 40-60 mg twice daily on Days 1-28, every 42 days for 3 cycles.\n\nThe primary study endpoint is the 2-year recurrence-free survival (RFS) rate. Secondary study endpoints include the 2-year overall survival (OS) rate, locoregional control rate, and incidence of grade ≥3 adverse events.\n\nA total of 92 patients are planned for enrollment in this trial.",[25],"Extrahepatic Cholangiocarcinoma and Gallbladder Carcinoma","RECRUITING","2026-06-21",{"date":29,"type":30},"2026-06-24","ACTUAL",{"date":32,"type":30},"2026-06-16",{"date":34,"type":19},"2029-05-30",{"name":36,"class":37},"Cancer Institute and Hospital, Chinese Academy of Medical Sciences","OTHER",""]
