No significant difference in tumor mutational burden (TM, microsatellite instability, and CD274 (encoding PD-L1) amplification was observed between PD-L1positive and PD-L1negative CXC subsets. By combining TMB with PD-L1, an additional 17 patients are eligible for pembrolizumab when compared to PD-L1 testing alone. TERT promoter alterations and APOBEC mutational signature were enriched in the PD-L1positive CXC SCC (p = 0.011, and p = 0.004, respectively). Our study reveals important prevalence data on PD-L1 positiv
