[Conservative treatment of breast carcinoma with or without prophylactic chemotherapy. Preliminary results in 45 cases (author's transl)].

Between February 1969 and December 1979, 45 breast carcinomas T1 NO or T2 NO (greater than 3cm) were treated by tumorectomy and radiotherapy. Axillary dissection was performed in 22 cases. Twenty-one pre-menopausal patients were castrated either by oophrectomy (13 cas) or by pelvic irradiation (8 cases). From 1977 on, (10 cases) prophylactic chemotherapy using cyclophosphamide, 5 FU, methotrexate, vincristine, was administered for 4 to 6 months according to the number of poor prognostic factors. The five-year actuarial remission rate was 93% (84-100), the metastatic remission rate was 88% (72-100). Indications of prophylactic chemotherapy in forms with good prognostic factors are discussed.
