Abstract

BACKGROUND: The aim of this randomized clinical trial was to evaluate the efficacy and safety of combination (cDC) and sequential (sDC) weekly docetaxel and carboplatin in women with recurrent platinum-sensitive epithelial ovarian cancer (EOC). METHODS: Participants were randomized to either weekly docetaxel 30 mg/m 2 on days 1 and 8 and carboplatin area under the curve (AUC) = 6 on day 1, every 3 weeks or docetaxel 30 mg/m 2 on days 1 and 8, every 3 weeks for 6 cycles followed by carboplatin AUC = 6 on day 1, every 3 weeks for 6 cycles or until disease progression. The primary endpoint was measurable progression-free survival (PFS). RESULTS: Between January 2004 and March 2007, 150 participants were enrolled. The response rate was 55.4% and 43.2% for those treated with cDC and sDC, respectively. The median PFS was 13.7 months (95% confidence interval [CI], 9.9-16.8) for cDC and 8.4 months (95% CI, 7.1-11.0) for sDC. On the basis of an exploratory analysis, patients treated with sDC were at a 62% increased risk of disease progression compared to those treated with cDC (hazard ratio = 1.62; 95% CI, 1.08-2.45; P =.02). The median overall survival time was similar in both groups (33.2 and 30.1 months, P =.2). The incidence of grade 2 or 3 neurotoxicity and grade 3 or 4 neutropenia was higher with cDC than with sDC (11.7% vs 8.5%; 36.8% vs 11.3%). The sDC group demonstrated significant improvements in the Functional Assessment for Cancer Therapy-Ovarian, Quality of Life Trial Outcome Index scores compared with the combination cohort (P =.013). CONCLUSIONS: Both cDC and sDC regimens have activity in recurrent platinum-sensitive EOC with acceptable toxicity profiles. The cDC regimen may provide a PFS advantage over sDC.
