Impact of epidermal growth factor receptor and KRAS mutations on clinical outcome in resected non-small cell lung cancer patients.
Surgery yields best results for non-small cell lung cancer (NSCLC) patients. Epidermal growth factor receptor (EGFR) and its downstream factor Kirsten rat sarcoma viral oncogene homolog (KRAS) are variably mutated in NSCLC. Such mutations predict clinical response to tyrosine kinase inhibitors. This study evaluated incidence and correlation of EGFR and KRAS mutations with clinicopathologic parameters and outcome in resected stage I to III NSCLC. ⋯ EGFR and KRAS mutations are frequent in ADCs and are not prognostic factors for survival. EGFR mutations could be used to identify patients suitable for adjuvant treatment with targeted therapy resulting in potentially improved outcomes.
