The addition of bevacizumab to chemoimmunotherapy was associated with improved survival in ns-NSCLC specifically in patients with LMs. These hypothesis-generating findings suggest that the benefit may stem from disruption of VEGF-A-driven immunosuppressive signaling in the liver, but require prospective confirmation.

In contrast, the same regimen showed inferior OS relative to many comparators (HR range for comparators vs. toripalimab plus chemotherapy: 0.47-0.65) and had the lowest OS ranking in SQ-NSCLC (SUCRA = 0.09). In the PD-L1 < 1% subgroup, nivolumab plus ipilimumab demonstrated a trend toward better OS compared with pembrolizumab plus chemotherapy (HR = 0.59) and ranked as the best regimen for SQ-NSCLC (SUCRA = 0.83), whereas pembrolizumab plus chemotherapy provided the greatest OS benefit for non-SQ-NSCLC (SUCRA = 0.90). In the PD-L1 ≥ 50% subgroup, atezolizumab plus chemotherapy ranked second for OS benefit in SQ-NSCLC but was the least effective combination in non-SQ-NSCLC; conversely, cemiplimab plus chemotherapy was the least effective combination in SQ-NSCLC but ranked second in non-SQ-NSCLC. The efficacy of individual first-line ICI regimens appear to vary by histological subtype across PD-L1 expression levels. These findings suggest that PD-L1 status alone might not be sufficient to guide treatment selection, and that histological subtype could be considered in clinical decision-making for advanced NSCLC.
