The ICIs treatment NSCLC cohort from the Memorial Sloan Kettering Cancer Center (MSKCC) was used for exploring the associations of mutations in the clock genes (CLOCK, BMAL1, CRY1, CRY2, PER1, PER2, and PER3) with TMB, tumor neoantigen burden (TNB), and ICIs efficacy....Compared to the WT group, patients in the MT group had a significantly longer median progression-free survival (PFS) (23.0 vs 5.2 months, HR: 0.45 [95%CI: 0.25-0.81], P = 0.0216) with PD-1 plus CTLA-4 blockade.
