CD274 and non-small cell lung carcinoma: In addition, TP53, KRAS, LRP1B, FAT atypical cadherin 3 (FAT3), KMT2D, and kelch like ECH‐associated protein 1 (KEAP1) mutations occurred frequently in patients with NSCLC (Table S3) and were significantly, positively correlated with TMB (p = 0.007, p < 0.001, p < 0.001, p < 0.001, and p < 0.001, respectively), and with the expression of PD‐L1 (p < 0.001, p = 0.009, p = 0.047, p = 0.015, and p = 0.004, respectively) (Figure 1C and 1D).
