BREAST CANCER—TRIPLE-NEGATIVE/CYTOTOXICS/LOCAL THERAPY 1001 Oral Abstract Session, Tue, 9:45 AM-12:45 PM Randomized phase III study of adjuvant chemotherapy for high-risk, node-negative breast cancer (BC) comparing FAC with FAC followed by weekly paclitaxel: First efficacy analysis of the GEICAM/2003-02 trial.

The role of wP in these pts is not well established yet. Methods: Pts aged 18-70, with T1-T3/N0 operable BC and at least one high-risk St Gallen 1998 criteria (size Ͼ2 cm, hormone-receptor [HR] negative, grade 2/3, age Ͻ35 years,) were eligible. HER2ϩ pts were allowed, after 792 entered the trial, the study was amended to exclude them. Pts were stratified by site, menopausal status, nodal status diagnostic method (sentinel-node biopsy versus lymphadenectomy) and HR status and randomized to receive FAC x6 (500/50/500 mg/m2 every 3w) or FAC x4¡wP x8 (paclitaxel 100 mg/m2 weekly). The primary endpoint was DFS. The trial was designed to detect an absolute 5-y DFS increase of 5% (80% FAC, 85% FAC¡wP); a sample size of 1812 evaluable patients (906 per arm) was required to detect this difference (␣ϭ0.05, ϭ 80%). Assuming a drop-out rate of 6%, 1929 pts were required. The first analysis of DFS was planned when a median follow-up of 5 years was reached. Results: Between September 2003 and October 2008, 1925 pts (FAC 974, FAC¡wP 951) were randomized. Patient characteristics were well balanced between arms, median age was 50, 73% of pts were HR positive and 9% HER2 positive. 97% of pts with FAC and 85% of pts with FAC¡wP completed all treatment as planned. The median dose intensity was 98% with FACx6, 99% with FACx4 and 98% with wP. The most frequent grade 3-4 toxicities (Ͼ3% in either arm) with FAC vs FAC¡wP were neutropenia (25% vs 22%) with 4% vs 3% of febrile neutropenia, fatigue (3% vs 8%), sensory neuropathy (0 vs 5%), and vomiting (4% in each arm). After a median follow-up of 5.3 years, the proportion of patients disease free is 93% and 90% with FAC¡wP and FAC (HR for relapse 0.732, 95% CI: 0.542 to 0.990; log-rank p-valueϭ0.0423). Conclusions: For pts with high-risk node-negative BC, adjuvant FAC¡wP was associated with a small but significant improvement in DFS compared with FAC, with manageable toxicity. © 2012 American Society of Clinical Oncology.
