In order to avoid modified radical mastectomy, a neoadjuvant approach was adopted in our institute for operable bulky breast cancers. From January, 1982, to December, 1995, 288 patients received primary chemotherapy with 3 different regimens (all doses mg/m2): (1) AVCF/AVCFM, 167 patients (adriamycin 30, vincristine 1 d1, cyclophosphamide 300, fluorouracil 400 d2-d5 and methotrexate 20 d2 and d4, every 28 days); (2) NEM, 78 patients (vinorelbine 25, epirubicin 35, methotrexate 20 d1 and d8, every 28 days); and (3) TNCF, 43 patients (THP-adria 20, d1-d3, vinorelbine 25 d1 and d4, cyclophosphamide 300, fluorouracil 400 d1-d4, every 21 days). Evaluation of the response comprised 3 methods: clinical (C), echographic (E), mammographic (M). The overall objective response rate (C : 63/90/93; E: 49/61/85; M: 53/65/83%) is higher with regimens (2) and (3). The complete response rate was increased 2-fold with TNCF but the hematologic toxicity was very superior with this combination. Patients were all operated for (2) and (3), only several for (1), and the breast conservation rate (68/83/79%) was quite similar in the 3 regimens. The pathological complete response rate reached 23% with TNCF. However the impact on patient survival has to be confirmed.
