title: [Colloid cancers of the breast. Value of radiotherapy. A series of 138 cases treated at the Curie Institute].
abstract: A series of 138 mucinous breast carcinomas was treated at the Institut Curie from 1970 to 1980: 107 were diagnosed as "pure" mucinous carcinoma and 31 as "mixed" mucinous carcinomas. Fifty per cent of the cases were stage T2 and 78% N0-N1a. Treatment methods were radical mastectomy in 113 cases (82%) with pre-operative irradiation for 37 patients and post-operative irradiation for 14 patients. A conservative treatment was used for 25 patients, consisting either of lumpectomy followed by radiotherapy (in 15 cases) or radiotherapy alone (in 10 cases). The five-year actuarial survival rate was 81% for the "pure" group and 87% for the "mixed" group; it was 70 and 75%, respectively, at ten years follow-up. In this series, survival was not influenced by the type of treatment. The efficacy of radiotherapy was evaluated from the local recurrence rate: only four local failures among the 25 conservative treatments were noted. Our conclusion is that radiotherapy, with or without lumpectomy, is efficient in mucinous breast carcinoma and could be useful in selected cases.
