There has been no report about re-challenge chemotherapy (RC) consisting of the same regimen as first-line chemotherapy in non-small-cell lung cancer (NSCLC). The aim of this study was to evaluate the efficacy of RC as second-line chemotherapy in patients with relapsed NSCLC. We conducted a retrospective review of 28 consecutive NSCLC patients who were treated with RC and compared their clinical outcomes with those of 38 consecutive NSCLC patients who were treated with docetaxel (DOC) at our hospital between July 1992 and December 2003. The RC group consisted of 21 men and 7 women, with a median age of 62 years (range, 42-76 years). Most first-line regimens were platinum-based and the median administered course was 3 (range, 2-7). All patients had responded to the first-line chemotherapy and had performance status (PS) 1 at relapse. The median interval from the end of first-line chemotherapy to relapse was 5.0 months (range, 1.6-36.1 months). The overall response rate of RC was 29%. The median survival time from the beginning of RC was 17.0 months and the 1-year survival rate was 60%. RC led to a significantly better overall survival rate than DOC (p=0.0342). RC could be an active second-line regimen in patients with relapsed NSCLC who responded to first-line chemotherapy.
