Clinicopathological features, including sex, age, tumor–lymph node–metastasis stage, tumor differentiation, smoking status, histological subtypes, and survival information were analyzed.Result: KRAS mutation was detected in 113 of 1,368 patients. Nine different subtypes of KRAS mutation were identified in codon 12, codon 13, and codon 61. KRAS mutation was more frequently found in male patients and former/current smoker patients. Tumors with KRAS mutation had poorer differentiation. Invasive mucinous adenocarcinoma predominant and solid predominant subtypes were more frequent in KRAS mutant patients. No statistical significance was found in relapse-free survival or overall survival between patients with KRAS mutation and patients with other mutations.Conclusion: In Chinese populations, we identified KRAS mutation in 8.3% (113/1,368) of the patients with lung adenocarcinoma. KRAS mutation defines a molecular subset of lung adenocarcinoma with unique clinicopathological features.Keywords: KRAS, NSCLC, surgery, prognosishttps://www.dovepress.com/the-prevalence-and-prognostic-significance-of-kras-mutation-subtypes-i-peer-reviewed-article-OTTKRAS Lung adenocarcinoma |
