POLR2A/TPR mutations were significantly associated with better PFS in Rizvi2015 cohort (HR = 0.3; 95% CI, 0.09-1.02; P = 0.041), MIAO2018 cohort (HR = 0; 95% CI, 0-INF; P = 0.01)....Our finding suggests that POLR2A/TPR mutations were associated with better PFS in NSCLC patients treated with Immunotherapy, with significantly higher TMB and TNB.
