We aimed to investigate whether integration of November 10, 2009 capecitabine into such a regimen enhances outcome.
See Online/Refl ection and Methods In this open-label trial, we randomly assigned (centrally by computer; stratifi ed by node status, HER2 status, Reaction and centre) 1500 women with axillary node-positive or high-risk node-negative breast cancer to either three cycles of DOI:10.1016/S1470- capecitabine and docetaxel followed by three cycles of cyclophosphamide, epirubicin, and capecitabine (capecitabine 2045(09)70340-7 group, n=753), or to three cycles of docetaxel followed by three cycles of cyclophosphamide, epirubicin, and fl uorouracil Department of Oncology, (control group, n=747). The primary endpoint was recurrence-free survival. A planned interim analysis was done Helsinki University Central after 3 years’ median follow-up. Effi cacy analyses were by modifi ed intention to treat. The study is registered with Hospital, Helsinki, Finland ClinicalTrials.gov, number NCT00114816.
