ABSTRACT
Three hundred eleven patients with node-positive breast cancer were randomized to one of three adjuvant treatments cyclophosphamide (Cytoxan), methotrexate, and 5-fluorouracil; all of the above with tamoxifen citrate; or all of the above with tamoxifen and bacillus Calmette-Guerin vaccination. Local therapy for all patients was a modified radical mastectomy. Estrogen receptors were measured on all primary tumors. Patients were stratified by the number of positive nodes (one to three nodes and more than three nodes) and estrogen-receptor value (less than 3 femtomole/mg and greater than or equal to 3 femtomole/mg). Follow-up is available, with a mean of 9.1 and maximum of 14.2 years. In this study the efficacy of short-term tamoxifen is apparent over that of chemoimmunotherapy alone and continues to be significant with prolonged follow-up. The addition of tamoxifen to chemoimmunotherapy significantly prolonged disease-free survival among patients with estrogen receptor-positive tumors who were postmenopausal, who had larger tumors (greater than 3 cm), or who had more extensive axillary node involvement (more than three nodes). Tamoxifen improved overall survival for patients with estrogen receptor-positive tumors larger than 3 cm. The addition of bacillus Calmette-Guerin Cytoxan, methotrexate, 5-fluorouracil, and tamoxifen did not significantly alter disease-free or overall survival.
