A Study of Bemosubaiabimab Combined With Anlotinib and Radiotherapy and Chemotherapy for the Treatment of Oligometastatic Esophageal Cancer

This study aims to evaluate the efficacy and safety of bemosubabimab combined with anlotinib and radiotherapy and chemotherapy in the treatment of patients with oligometastatic esophageal cancer. The study adopted a single-center, single-arm trial design. Eligible patients with oligometastatic esophageal squamous cell carcinoma were treated with bemosubaiabant, anlotinib, and combined radiotherapy and chemotherapy for 4 to 6 cycles, followed by maintenance treatment with bemosubaiabant and anlotinib. During the study period, the subjects were not allowed to receive any other anti-tumor treatments. If the dose of anlotinib hydrochloride was adjusted due to safety events for the subjects, the anlotinib hydrochloride would be dispensed according to the investigator's prescription.
