[Value of reduction mammoplasty in the conservative treatment of breast neoplasms. Apropos of 70 cases].

Breast cancer surgery is on the increase. Until now conservative treatment has been limited to tumors less than 3 cm; it is now extending to surgery on reduced tumors after chemotherapy or radiotherapy. Some cancers still require mastectomy because a carcinologic satisfactory tumorectomy would create a major deformity not compatible with conservative treatment. It is technically possible to perform major tumor resection with good cosmetic results using the reduction mammoplasty technique well known in plastic surgery. Between 1983 and 1991, 70 patients were treated at Henri Mondor Hospital for breast cancer with breast reduction mammoplasty and irradiation. We present the result with an average five years follow-up in terms of the cosmetic results relapses and survival rate. The actuarial local relapse was less than 10%, the survival with local relapse was 86% after 5 years, cosmetic results were good in 81% of cases. The association of reduction mammoplasty and radiotherapy seems to be a good extension of conservative treatment in some large breast tumors.
