This study evaluated the benefits of immune checkpoint inhibitors (ICIs) and/or targeted therapies in mismatch repair-deficient (dMMR) and mismatch repair-proficient (pMMR) patients with advanced or recurrent endometrial cancer (EC) via network meta-analysis. English databases were searched from inception through January 2025. Randomized controlled trials (RCTs) assessing the efficacy and safety of related therapies for patients with EC stratified by MMR status were included. The main evaluation indicators included progression-free survival (PFS), overall survival (OS), the objective response rate (ORR), and severe adverse events (SAEs). Ten studies were included in the analysis. The results indicated that in the dMMR population, ICIs provide superior survival benefits. Among these, Dostarlimab combined with carboplatin and paclitaxel (CP) had the highest PFS and OS rates. For the pMMR population, Selinexor + CP offers significant benefits over CP alone, although OS outcome data are limited. In pMMR patients with prior chemotherapy, the lenvatinib + pembrolizumab strategy may provide additional PFS benefits relative to chemotherapy treatment. ICIs offered advantages for the dMMR population, whereas selinexor could provide survival benefits for the pMMR population. For pMMR patients who have received prior chemotherapy, the lenvatinib plus pembrolizumab strategy shows promise.
