| Popis: | Purpose: To compare the sequential versus the concurrent administration of epirubicin and docetaxel as adjuvant therapy in high risk axillary node negative women with early breast cancer. Patients and treatment: Women 18-75 years old with invasive breast adenocarcinoma surgically resected with no infiltrated axillary lymph nodes and absence of metastatic disease were randomized to receive 4 cycles of epirubicin 90mg/m2 followed by 4 cycles of docetaxel 75mg/m2 (sequential regimen) or 6 cycles of epirubicin 75mg/m2 followed by docetaxel 75mg/m2 (concurrent regimen). All chemotherapy cycles were administered every 21 days with prophylactic G-CSF support for days 3-10 only for the concurrent regimen. Stratification was based on menopausal status, tumor size and hormone receptor expression. By protocol amendment in 2008 women with HER2 positive tumors were excluded. The primary endpoint of the study was to compare the disease-free survival (DFS) at 5 years and 329 patients were scheduled to enroll on each arm. Results: Between 2001-2013, 658 women were randomized and received the sequential (n=329) or the concurrent (n=329) regimen. The median age was 53 and 52 years, premenopausal status 43.8% versus 44.1%, tumor size Conclusion: In this interim analysis both the efficacy and the toxicity profile seem to favor the sequential over the concurrent regimen.
