摘要: Retrospective studies suggested a benefit of first-line tyrosine kinase inhibitor (TKI) treatment continuation after response evaluation in solid tumors (RECIST) progression epidermal growth factor receptor (EGFR)-mutated non-small-cell lung cancer (NSCLC) patients. The aim this multicenter observational retrospective study was to assess the frequency practice and its impact on overall survival (OS). analysis included advanced EGFR-mutated NSCLC patients treated with TKI who experienced RECIST between June 2010 July 2012. Among 123 (67 ± 12.7 years, women: 69 %, non smokers: 68 PS 0–1: 87 %), 40.6 % continued therapy progression. There no difference did not continue respect progression-free (PFS1: 10.5 versus 9.5 months, p = 0.4). Overall (OS) showed non-significant trend favor continuing (33.0 vs. 21.2 0.054). Progressions were significantly less symptomatic group than discontinuation (18 37 1 (HR 4.33, 95 %CI: 2.21-8.47, 0.001), >1 one metastatic site 1.96, 1.06-3.61, 0.02), brain metastasis 1.75, 1.08-2.84, 0.02) at diagnosis, towards higher risk death cases 1.62, 0.98-2.67, 0.056 ). In multivariate only 6.27, 2.97-13.25, 0.00001) 2.54, 1.24-5.21, diagnosis remained significant. This suggests that under certain circumstances, is an acceptable option
