Carcinome canalaire in situ du sein. Analyse de 882 cas

Mastectomy remains the safest treatment for women with DCIS, with a 98% 7-year control rate. After conservative surgery, RT reduces very significantly LR rates, according to the NSABP B-17 and EORTC 10853 randomized trial results. The RT benefit is present in all clinical/histological subgroups, but its magnitude varies. Young age (<40 years) and incomplete excision are the most important LR risk factors.
