PD-L1, Tumor Mutational Burden, and Outcomes in NSCLC With Brain Metastases: A Brief Report.

Cumulative incidence of radiographic RN at two years was numerically higher in patients with higher PD-L1 (2.3% versus 5.5% versus 9.3% for PD-L1 < 1%, 1%–49%, and ≥50%, respectively; Supplementary Table 6 ), but did not reach statistical significance ( p 1%–49% versus <1% = 0.15, p ≥50% versus <1% = 0.08; Fig. 2 B ).
