BACKGROUND: In an earlier study, we have demonstrated a high response rate in metastatic breast cancer using paclitaxel (P) and cisplatin (C). A phase II study using the same regimen (PC) has been conducted in locally advanced breast cancer (LABC). METHODS: A total of 72 consecutive patients with non-inflammatory LABC (T2 > or = 4 cm, T3 or T4, N0-N2, M0). Patients were scheduled to receive 3-4 cycles of the neoadjuvant PC (paclitaxel 135 mg/m2 and cisplatin 75 mg/m2 on day 1) every 21 days. Patients were then subjected to surgery and subsequently received 6 cycles of FAC (5-fluorouracil 500 mg/m2, doxorubicin 50 mg/m2, and cyclophosphamide 500 mg/m2) or 4 cycles of AC (doxorubicin 60 mg/m2, and cyclophosphamide 600 mg/m2). Patients then received radiation therapy, and those with hormone receptor positive tumors were given adjuvant tamoxifen intended for 5 years. RESULTS: The median age was 39 years (range, 24-78). Clinically, 7%, 58%, and 35% of patients had T2 > or = 4 cm, T3, and T4, respectively. Disease stage at diagnosis was IIB (33%), IIIA (27%), and IIIB (40%). Complete and partial clinical response to PC was demonstrated in 13 (18%), and 52 (72%) patients, respectively. Of those patients with evaluable pathologic response (68 patients), complete pathologic response (pCR) was achieved in 15 (22%) patients. At a median follow-up of 22 (+/- 3.5) months, 58 (81%) were alive with no recurrence, nine (12%) were alive with evidence of disease, and five (7%) were dead. None of the patients achieving pCR has developed any relapse. The median overall survival has not been reached for all 72 patients with a projected 3-year survival (+/- SE) of 90% (+/- 4%). The median progression-free survival (PFS) was 42.1 (+/- 4.8) months with a projected PFS of 74% +/- 7% at 3-years (for 68 patients). CONCLUSIONS: PC regimen in LABC produced a high pCR. The contribution of the other added modalities to survival could not be assessed.
