Description
In a retrospective study, 166 non-small cell lung cancer (NSCLC) patients that tended to have selected characteristics known to be predictive for TKI sensitivity (i.e. women, never smokers, and patients with ADC) were treated with either gefitinib or erlotinib. EGFR mutations (n=42) were associated with improved objective response to drug treatment (71.4% vs. 20.1%, p<0.0001), improved but not significant overall survival (36.9 vs. 24.8 months, p=0.09), and longer median time to progression (not reached vs. 3.7 months, p<0.0001) when compared to wild-type EGFR. Through multivariate analyses, it was shown that EGFR mutations are independent predictive favorable factors of response to drug treatment (p<0.0001) and are significant predictors of longer time to progression (HR: 0.27, 95% CI: 0.14-0.52, p=0.0001)
