摘要: Purpose We undertook this analysis of KRAS mutation in four trials adjuvant chemotherapy (ACT) versus observation (OBS) to clarify the prognostic/predictive roles non–small-cell lung cancer (NSCLC). Methods was determined blinded fashion. Exploratory analyses were performed characterize relationships between status and subtype survival outcomes using a multivariable Cox model. Results Among 1,543 patients (763 OBS, 780 ACT), 300 had mutations (codon 12, n = 275; codon 13, 24; 14, 1). In OBS patients, there no prognostic difference for overall codon-12 (mutation v wild type [WT] hazard ratio [HR] 1.04; 95% CI, 0.77 1.40) or codon-13 (HR 1.01; 0.47 2.17) mutations. No significant benefit from ACT observed WT-KRAS (ACT HR 0.89; 0.76 P .15) 0.95; 0.67 1.35; .77); with mutations, deleterious 5.78; 2.06 t...
