الوصف: | Immune checkpoint inhibitors (ICIs) have become important treatment strategies, yet responses vary among patients and predictive biomarkers are urgently needed. Mutations in KMT2C and KMT2D lead to increased levels of genomic instability. Therefore, we aimed to examine whether KMT2C/D mutations might be a predictor of immunotherapeutic efficacy. Herein, we investigated the associations of KMT2C/D loss-of-function (LOF) variants with TMB, MSI-H, PD-L1 expression, the levels of tumor-infiltrating leukocytes (TILs), and clinical response to ICIs. It was found that KMT2C/D LOF variants were associated with higher TMB. Compared to the non-LOF group, the proportion of patients with MSI-H tumors was larger in the LOF group. The PD-L1 expression was higher in the LOF group only for colorectal cancer in both the Chinese and TCGA cohorts. Importantly, KMT2C/D LOF variants were associated with decreased regulatory T cells and increased levels of CD8 |
