title: Sequential chemotherapy, surgery and radiotherapy in locally advanced breast cancer.
abstract: Thirty-seven patients with locally advanced breast cancer, 86% of whom had skin involvement, were treated with three to six cycles of vincristine 1.4 mg m-2, doxorubicin 40 mg m-2 and cyclophosphamide 600 mg m-2. A complete response rate of 19%, and overall response rate of 61% were achieved. Fourteen patients had received a trial of hormone therapy, but no patient had been given prior cytotoxic chemotherapy or radiation therapy. In no case was chemotherapy discontinued on account of toxicity. In patients with partial remission where gross disease more than 3 cm remained, mastectomy (10 patients) or local excision (five patients), was carried out increasing the complete remission rate to 49%. Thirty-two patients then received 45 Gy in 24 days to the breast and regional lymphatics with a further 12 Gy boost to the tumour site. The overall response rate achieved was 86% of the 37 patients, with a total, complete response rate of 76%. The median time to relapse in the 28 complete responders was 17 months. Local palliation, defined as absence of pain, ulceration or an enlarging mass was achieved in 92% of the total number of patients, and the projected local palliation rate at 2 years by life table analysis was 60%. Only 50% of the 10 N3 patients were alive at 1 year, compared to 93% of the 27 N0-N2 patients (P less than 0.05). The overall survival in the entire group at 2 years was 50%. This is an effective and tolerable combined modality approach for the control of local disease in a subgroup of breast cancer patients with complex management problems.
