摘要: Purpose Gefitinib, an inhibitor of the epidermal growth factor receptor tyrosine kinase, induces radiographic regressions and symptomatic improvement in patients with non–small-cell lung cancer (NSCLC). Phase II trials suggested female sex adenocarcinoma were associated response. We undertook this analysis to identify additional clinical pathologic features sensitivity gefitinib. Patients Methods reviewed medical records, material, imaging studies all 139 NSCLC treated on one three consecutive gefitinib monotherapy performed at our institution. identified experiencing a major objective response compared their others. Univariate multivariable analyses potential predictive Results Of patients, 21 (15%; 95% CI, 9% 21%), experienced partial Variables as signif...
