Induction chemotherapy with cisplatin, doxorubicin, and cyclophosphamide (CAP) in a combined modality approach for locally advanced and inflammatory breast cancer. Long-term results.
Thirty-one patients with locally advanced and inflammatory breast carcinoma (stage IIIA and IIIB) were treated with a combined modality approach between 1985 and 1989. All patients received as induction chemotherapy a combination of cisplatin, doxorubicin, and cyclophosphamide (CAP). Responsive patients and patients with operable stable disease underwent modified radical mastectomy followed by concurrent radiotherapy and CMF (cyclophosphamide, methotrexate, 5-fluorouracil) adjuvant chemotherapy. Thirty patients were evaluable for response to CAP. The rate of objective response to induction chemotherapy was 76.7% with 2 patients (6.7%) obtaining a complete response and 21 patients (70%) a partial response. Twenty-five patients were rendered disease-free after induction chemotherapy and surgery. Only 2 of these had pathological complete response (8%). The median overall survival was 48.7 months, the median time to progression was 22.4 months and the median disease-free survival was 29.1 months. The patients with noninflammatory breast tumor had a significantly better overall survival, disease-free survival, and time to progression. The overall survival and the time to progression were statistically superior in patients with primary tumor size < or = 8 cm. At a median follow-up of 6 years, 29% (95% CI, 13.05 to 45.01) of patients were alive and 28% (95% CI, 10.4 to 45.6) were disease-free. This combined modality treatment seems feasible with quite acceptable toxicity; the CAP combination is an effective alternative to the other standard chemotherapeutic regimens. Our results, although encouraging, are still poor, and new drugs and strategies are required to improve the long-term outcome.
