title: [Role of chemotherapy in the treatment of bone metastases of breast cancer].
abstract: This study was made on 98 patients with breast cancer, whose first discovered metastasis was to the bone, a mean of 2.8 years following the initial diagnosis. It is most often a lytic lesion, and the majority of patients have more than two areas on bone scintiscan. About half of the patients received palliative radiotherapy; 16 had to undergo surgery for or to prevent pathologic fractures. All patients underwent chemotherapy with vincristine or vinblastine, methotrexate or cyclophosphamide, 5-fluorouracil and, in 37 cases, the addition of adriamycin. Half of the patients also received tamoxifen. Present studies show a mean survival of 31 months with 24% survival at five years. Age, the interval to the discovery of the first metastasis, the use of additional chemotherapy following surgery for the breast lesion, the sedimentation rate, and the number of bony metastases do not play any prognostic role. However, the prognosis is significantly improved by adding tamoxifen, and even more so by adding adriamycin to the chemotherapeutic protocol since mean survival improves from 26 to 52 months. The reduced incidence of bony metastases with chemotherapy following surgery had led some authors to believe that prevention is the best method of treating bony metastases from breast cancer.
