NCT07636824

Brief Summary

This is a multicenter, open-label, single-arm, prospective Phase II clinical trial. 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/m² 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/m² 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. The 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. A total of 92 patients are planned for enrollment in this trial.

Study Arms (1)

Postoperative Concurrent Chemoradiotherapy Group

EXPERIMENTAL
Radiation: Postoperative radiotherapyDrug: Capecitabine or S-1

Interventions

During radiotherapy, concurrent oral capecitabine will be administered at a dose of 1,600 mg/m² 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/m² 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.

Postoperative Concurrent Chemoradiotherapy Group

All patients will receive postoperative concurrent chemoradiotherapy with IMRT or 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.
