摘要
Immune checkpoint inhibitors (ICIs) are one of the most promising approaches toward advanced melanoma. Here, we aimed to perform a meta-analysis of randomized controlled trials (RCTs) to evaluate the efficacy of all studied ICIs. We conducted a comprehensive search to identify the relevant publications (PROSPERO registration ID: CRD42023470649). Then we performed a meta-analysis to evaluate the efficacy of different ICIs for metastatic melanoma. We used Cochrane’s tool to assess the quality of studies. The outcome measures were overall survival (OS), progression-free survival (PFS), and recurrence-free survival (RFS). Twenty reports of RCTs entered our systematic review, 18 of which were included in our data analysis. ICIs showed improved survival compared with control group (hazard ratio (HR) = 0.57; 95% CI: 0.43–0.71; P<0.001). Using a meta-regression, we found a significant relation between patients’ mean age and their OS (P<0.001, R2 = 100.00%). Also, our analysis revealed greater HR for CTLA-4 inhibitors than PD-1/PD-L1 inhibitors (HR = 0.71, 95%CI: 0.63–0.79, P<0.001 vs. HR = 0.63, 95%CI: 0.46–0.79, P<0.001). The effect sizes of different types of PD-1/PD-L1 inhibitors were comparable Our results suggest that ICI-based immunotherapy is associated with enhanced OS, PFS, and RFS (P < 0.001) and will assist clinicians in choosing the optimal approach toward treating metastatic melanoma.
