Abstract

ABSTRACTA retrospective analysis of all breast cancer primarily treated at this institution during the ten-year period from 1967 to 1977 revealed 336 cases; in 308 of these cases, complete follow-up of five or more years was available. Clinical staging using the TNM system (tumor, node, metastasis) showed stage I disease in 60 patients, stage II in 94, stage III in 105, and stage IV in 49. Pathologic classification of these 308 cases showed a high incidence of infiltrating ductal carcinoma (88%). Early in the study operative treatment consisted of radical mastectomy, with modified radical mastectomy being more common in the later years. Simple mastectomy was occasionally done palliatively. Adjuvant treatment using cyclophosphamide (Cytoxan), methotrexate, 5-fluorouracil, radiation, and/or hormonal manipulation was then given according to a set protocol. In general, five- and ten-year survival improved with this combined treatment. The mortality among patients with stage I infiltrating ductal carcinoma not given adjuvant therapy suggests the need for proper selection of patients in this group who should receive adjuvant chemotherapy because they are at increased risk.
