Results of neoadjuvant chemotherapy and radiation therapy in the breast-conserving treatment of 250 patients with all stages of infiltrative breast cancer.
Two hundred fifty evaluable patients with breast cancer entered a protocol combining neoadjuvant and consolidation therapy by vinblastine (V), thiotepa (T), methotrexate (M), and 5-fluorouracil (F) (VTMF), with or without Adriamycin (A) (doxorubicin; Adria Laboratories, Columbus, OH), and radiation therapy as exclusive locoregional treatment. Tamoxifen was given to 195 patients (130 postmenopausal and 65 premenopausal) and was omitted in 55 patients (31 postmenopausal and 24 premenopausal). There were 19 Stage I, 86 Stage IIA, 51 Stage IIB, 36 Stage IIIA, and 58 Stage IIIB patients. Primary chemotherapy induced tumor volume regression of more than 75% in 41% of the patients and complete clinical regression in 30% of the patients. The 5-year disease-free survival (DFS) rates were 100% for Stage I, 82% for Stage IIA, 61% for Stage IIB, 46% for Stage IIIA, and 52% for Stage IIIB patients. Among the 72 primary relapses there were 39 distant metastases. The actuarial rate of locoregional recurrence was 13% for T2, 18% for T3, and 19% for T4. At 5 years the rate of breast preservation was 94%. Cosmetic results were excellent or good for most patients. The 5-year overall survival (OS) rates were 95% for Stage I, 94% for Stage IIA, 80% for Stage IIB, 60% for Stage IIIA, and 58% for Stage IIIB. Most patients with breast cancer should be given the option of breast-preserving treatment.
