BACKGROUND: For advanced non-small cell lung cancer (NSCLC), combination therapies including a PD-1 inhibitor plus chemotherapy or a PD-1 inhibitor, CTLA-4 inhibitor, and chemotherapy are standard first-line options. However, data directly comparing these regimens are lacking. This study compared the efficacy of pembrolizumab plus chemotherapy (CP) against nivolumab plus ipilimumab and chemotherapy (CNI) in a real-world setting.
METHODS: In this multicenter retrospective study, we compared the efficacy and safety of CP and CNI as first-line therapies in 182 patients with stage IIIB-IV NSCLC. Primary outcomes were overall survival (OS) and progression-free survival (PFS), while secondary outcomes included the response rate (RR) and safety profiles. Kaplan-Meier survival curves and Cox proportional hazards models were utilized for data analysis, adjusting for confounding factors such as age, gender, and PD-L1 expression.
RESULTS: In this study, 160 patients received CP, while 22 received CNI. The CP group was associated with significantly better PFS than the CNI group (median 11.7 vs. 6.6 months, HR 0.56, p = 0.03). This PFS advantage persisted after propensity score matching to adjust for imbalances. No significant OS differences were observed. Grade 3-4 adverse events occurred comparably, but immune-related adverse events were numerically more frequent in the CNI group.
CONCLUSIONS: In real-world practice, CP demonstrated superior PFS compared with CNI. These findings can inform treatment selection in advanced NSCLC.
