Effectiveness and safety of PD-1/L1 inhibitors as first-line therapy for patients with advanced or metastatic urothelial carcinoma who are ineligible for platinum-based chemotherapy: a meta-analysis.

ABSTRACT:

Objective

To evaluate the efficacy and safety of programmed cell death protein 1 or its ligand (PD-1/L1) inhibitors as first-line therapy in advanced or metastatic urothelial carcinoma (mUC) who are ineligible for platinum-based chemotherapy.

Method

A systematic search was conducted in four databases (Pubmed, Embase, Web of Science, and the Cochrane Library) to find articles that evaluate the effectiveness of first-line PD-1/L1 inhibitors for mUC, from the establishment of the databases to 22 November 2023. Meta-analyses were performed to evaluate the frequencies of progression-free survival (PFS), overall survival (OS), complete response (CR), partial response (PR), stable disease (SD), progressive disease (PD), objective response rate (ORR), disease control rate (DCR), and
