    Abstract:
    BACKGROUND: Different clinical trials for recurrent or metastatic nasopharyngeal carcinoma have studied different combinations of immuno-oncology in first-line treatment, but the optimal choice has not been determined. OBJECTIVE: To systematically examine and compare the efficacy and safety of different immune checkpoint inhibitors (ICIs) combined with chemotherapy as first-line treatment for recurrent or metastatic nasopharyngeal carcinoma. METHODS: Several electronic databases were systematically searched up to February 2023. Articles meeting the inclusion criteria were included. RESULTS: Three RCTs were eligible in the study. Compared with placebo plus gemcitabine-cisplatin (GP), toripalimab plus GP (HR = 0.59, 95% CI: 0.37-0.95) was significantly associated with a better OS. Tislelizumab plus GP generated best progression-free survival (PFS) benefit (HR = 0.50, 95% CI: 0.37-0.67), greatest improvement in 1-year PFS rate (RR = 3.00, 95% CI: 1.84-5.22), and objective response rate (ORR) (RR = 1.26, 95% CI: 1.04-1.53) over the placebo plus GP. Furthermore, tislelizumab plus GP appeared to be safer than toripalimab plus GP and camrelizumab plus GP in terms of adverse events (AEs)-grade ≥3, treatment-related AEs (TRAEs)-grade ≥3, serious AEs (SAEs), treatment-related SAEs (TRSAEs), and AEs leading to discontinuation of treatment. CONCLUSION AND RELEVANCE: In recurrent or metastatic nasopharyngeal carcinoma, programmed death 1 (PD-1) inhibitors plus GP as first-line treatment have better survival outcomes than placebo plus GP with comparable toxicity. Toripalimab plus GP shows the best OS benefit over placebo plus GP, while tislelizumab plus GP generates the best PFS, 1-year PFS rate, ORR, and safety. Tislelizumab plus GP could be the best choice among the ICIs combined with chemotherapy regimens as first-line treatment in recurrent or metastatic nasopharyngeal carcinoma.
