Brief summary: The study is a multicenter phase II randomized controlled trial. The purpose is to investigate the efficacy and safety of adjuvant immunotherapy combined with chemoradiation for patients with high-risk resectable extrahepatic cholangiocarcinoma and gallbladder cancer.

Detailed description: The trial will recruit 92 patients, and they will be randomized (1:1) into two groups (chemoradiation+immunotherapy group, observation group) after operation. Patients in chemoradiation+immunotherapy group will receive camrelizumab 200mg intravenously every 3 weeks until clinical or radiographic disease progression, unacceptable toxicity, death, termination of the study or withdrawal. After 1 or 2 courses of camrelizumab, patients went on to receive capecitabine (1,330 mg/m2 per day, in divided doses twice daily, 7 days per week) concurrent with radiotherapy (45 Gy to regional lymph nodes and 54 to 59.4 Gy to preoperative tumor bed). Patients in observation group will not receive any anti-cancer therapy.
