Abstract

Objective: To evaluate the KRAS mutation in non-small cell lung cancer patients at K hospital. Objects and methods: Retrospective description of 931 NGS test samples, including 758 tissue samples from non-small cell lung cancer patients at K Hospital from 1/2019. The test is done at HCMCT Genetics Institute using Massively parallel DNA by next generation sequencing technology. Results: KRAS mutation accounted for 20.1%; mainly occurs in men, accounting for 92%. 9% of the KRAS mutation occurs concurrently with another mutation (EGFR, ALK, BRAF, MET. PI3KCA). Mutations in Codon 12 accounted for 81.3%; codon 13 accounts for 18.7%. Conclusion: The KRAS mutation in the K hospital survey is consistent with the data in the literature
