title: Endocrine versus endocrine plus five-drug chemotherapy in postmenopausal women with stage II estrogen receptor-positive breast cancer.
abstract: Postmenopausal women who underwent modified radical mastectomy for Stage II, estrogen receptor (ER)-positive breast cancer were randomized to receive endocrine treatment (tamoxifen [T], 40 mg daily for 3 years) alone versus endocrine treatment plus five-drug chemotherapy (Cytoxan [cyclophosphamide, C], methotrexate [M], 5-fluorouracil [F], vincristine [V], and prednisone [P], CMFVP, for 1 year). Chemotherapy consisted of oral P (1 month), oral C (12 months), and intravenous MFV weekly for the first 3 months, biweekly for 3 months, and triweekly for 6 months. Patients were entered into the study from October 1979, to October 1985, and the median follow-up is 55 months. Results show that with 94 postmenopausal women, disease-free survival (DFS) is significantly greater (P = 0.04, log-rank test; P = 0.03, multivariate analysis) in patients receiving CMFVPT as compared to those receiving T alone. These results suggest that intensive chemotherapy combined with T is more effective in delaying recurrence than T alone in postmenopausal patients.
