Simultaneous Study of Docetaxel Based Anthracycline Free Adjuvant Treatment Evaluation, as Well as Life Style Intervention Strategies

This is an open-label, multicenter, 2x2 factorial design, randomized controlled, Phase III study comparing the disease free survival after randomisation in patients treated with 3 cycles of Epirubicine-Fluorouracil-Cyclophosphamide(FEC)-chemotherapy, followed by 3 cycles of Docetaxel(D)-chemotherapy, versus 6 cycles of Docetaxel- Cyclophosphamide (DC)-chemotherapy, and to compare the disease free survival in patients with BMI of 24 - 40 kg/m² after randomisation with versus without the lifestyle intervention. Patients will be required to have histopathological proof of a HER2/neu negative tumor and: axillary lymph node metastases (pN1-3) or high risk node negative, defined as: 'pT ≥2 or histopathological grade 3, or age ≤35 or negative hormone receptor status, but are not allowed to have evidence of distant disease. Patients will have to be entered into the study no later than 6 weeks after complete resection of the primary tumor. No other antineoplastic treatment other than surgical treatment, the defined cytotoxic and endocrine treatment and radiotherapy will be allowed prior to study entry and during the course of the study.
