    Squamous-cell lung carcinoma is one of the tumor types with the highest number of mutations since smoking, the main driver of the disease, is a strong mutagenic factor. [ 5 ] Inactivating mutations in lung SCC affect many tumor suppressor genes such as TP53 (mutated in 81% of cases), MLL2 (20%), CDKN2A (15%), KEAP1 (12%) and PTEN (8%).
