Abstract: Mutations in the epidermal growth factor receptor (EGFR) gene are the most common targetable genomic drivers of non-small cell lung cancer (NSCLC). Therefore, chemotherapy may increase the sensi - tivity to TKIs in patients harboring the 21‑L858R mutation. EGFR L858R is present in 1.12% of AACR GENIE cases, with lung adenocarcinoma, non-small cell lung carcinoma, small cell lung carcinoma, squamous cell lung carcinoma, and unknown having the greatest prevalence [4]. is L861Q in exon 21 consists of approximately 2% of EGFR-positive mutations, and is sometimes compounded with other mutations (34,35). open and 48 EGFR is altered in 4.38% of urothelial carcinoma patients EGFR is altered in 16.31% of anaplastic astrocytoma patients ORR and time to progression were not statistically different among L858R and exon 19 deletion patients.
