Abstract
- LBA5501 Background: Three-weekly (3w) CP is standard first-line chemotherapy for AOC pts. Weekly (w) P combined with 3w C prolonged PFS and OS in a JGOG phase III trial. MITO-7 is an academic randomized phase III study, comparing 3w vs. w CP. Methods: AOC chemonaive pts, stage IC-IV, age≤75, ECOG PS≤2, were randomized to 3wCP (C AUC6 + P 175mg/m², d1q21) for 6 cycles or to wCP (C AUC2 + P 60mg/m²) for 18 administrations. Coprimary endpoints were PFS and quality of life (QoL), measured by FACT-O and FACT/GOG-Ntx. With 80% power in detecting HR of 0.75, 2-sided α=0.05, 383 events were needed for PFS analysis. The arms were compared with a log-rank test and in a Cox model adjusted by stage, PS, residual disease, age and size of institution, following intention-to-treat. QoL was measured at baseline and weekly for 9 wks. Interaction between arm and QoL time was tested in a linear mixed model. Toxicity was coded by NCI-CTCAE v3.0. Results: 822 pts were enrolled by MITO, MANGO, and GINECO. Median age was 60; stage III (66%) and IV (18%) were prevalent. As of March 18, 2013, with median follow-up 20 months, 410 PFS events were recorded. Median PFS was 18.8 months with wCP and 16.5 months with 3wCP (HR 0.88, 95%CI 0.72-1.06, p=0.18). Lack of significant difference was confirmed (HR 0.87, 95%CI 0.71-1.05) in Cox model. For all scores, QoL course was significantly different between arms (p
