BackgroundWe performed a systematic review and meta-analysis to further explore the impact of the addition of immunotherapy to gemcitabine–cisplatin as first-line treatment for advanced biliary tract cancer (BTC) patients.MethodsLiterature research was performed, and hazard ratio values and 95% confidence intervals were calculated. Heterogeneity among studies was assessed using the tau-squared estimator (τ2). The total Cochrane Q test (Q) was also assessed. The overall survival rate, objective response rate, and progression-free survival in the selected studies were assessed.ResultsA total of 1,754 participants were included. Heterogeneity among the studies selected was found to be non-significant (p = 0.78; tau2 = 0, I2 = 0%). The model estimation results and the forest plot suggested that the test for the overall effect was significant (Z = −3.51; p< 0.01).ConclusionThe results of the current meta-analysis further confirm the role of immune checkpoint inhibitors plus gemcitabine–cisplatin as the new standard first-line treatment for advanced BTC patients.Systematic review registrationhttps://www.crd.york.ac.uk/prospero, identifier CRD42023488095.
