摘要: Rationale and Objectives The aims of this study were to investigate the association between 8-week tumor volume decrease survival in an independent cohort epidermal growth factor receptor ( EGFR )-mutant advanced non-small cell lung cancer (NSCLC) patients treated with first-line erlotinib or gefitinib, assess rate their volumetric after nadir. Materials Methods In NSCLC harboring sensitizing mutations computed tomography (CT) volumes dominant lesions analyzed for (1) survival, (2) Results 44 follow-up CT, (%) was significantly associated longer overall when fitted as a continuous variable Cox model P = 0.01). logarithm (log e V), obtained using linear mixed-effects adjusting time since baseline, 0.096/month (SE: 0.013/month; 95% confidence interval [CI]: 0.071–0.12/month), which similar 0.12/month 0.015/month; 95%CI: 0.090–0.15/month) observed previous report. Conclusions validated marker -mutant gefitinib. nadir that cohort, indicating reproducibility observation among different patient cohorts.
