The prevalence and prognostic value of KRAS co-mutation subtypes in Chinese advanced non-small cell lung cancer patients.

Our study revealed that concurrent genomic alterations can further stratify KRAS-mutant lung adenocarcinoma patients into various subgroups with distinctive therapeutic responses and differential survival outcomes. The KPL is a novel and less responsive subtype among KRAS-mutated NSCLC, and further investigation of effective treatment for this subtype is warranted.
