Résumé
BACKGROUND: The objective of this phase II study was to attempt to maximize response and survival in patients with bulky, operable breast cancer by combining sequential neoadjuvant docetaxel to a semi-intensive anthracycline-based regimen. PATIENTS AND METHODS: Eligible patients (N = 53) were included to receive 4 cycles of docetaxel, followed by a maximum of 4 cycles of TNCF (THP [theprubican]-doxorubicin/vinorelbine/cyclophosphamide/5-fluorouracil) every 21 days before definitive surgery and radiation therapy. RESULTS: After a median number of 4 cycles of docetaxel and 2 cycles of TNCF, the overall clinical response rate was 81.1%, including a 13.2% complete remission rate and only 2 incidences of progressive disease. Breast conservation was achieved in 87% of patients. According to Chevallier classification, a pathologic complete response in breast and axilla was confirmed in 6 patients (11.3%) and in 9 patients (17%) using the Sataloff's classification. The important myelosuppression observed in this trial was expected but limited by the prophylactic use of growth factors. After a median follow-up of 40.4 months, only 5 recurrences were documented, with a median time to first recurrence of 12.8 months. CONCLUSION: Despite disappointing results of this trial for pathologic complete response rate, possibly because of the order of drug administration, clinical response, breast conservation, and survival were optimized.
