PURPOSE: Mastectomy is necessary for 40% of the @entity513 in situ. If @entity0 ( @entity0 ) is systematically proposed, 81% of the @entity1 would choose immediate versus delayed breast reconstruction, but the actual @entity0 rate is only approximately 50% of them. Therefore, the aim of this study was to identify objective characteristics that distinguish the @entity1 who actually underwent @entity0 from those who did not. METHODS: Several criteria of 248 @entity1 who have undergone mastectomy for @entity513 were analyzed. Factors studied were age, body mass index, @entity6 , @entity286 use, and weight of the specimen of resection. RESULTS: The rate of @entity0 was 43%. An increase in age and weight of the resection specimen, irrespective of the body mass index, was associated with a lower rate of @entity0 . Thus, an increase of 100  g in the weight of the breast induces a significant reduction of the @entity0 (33%). CONCLUSIONS: In our series, older @entity1 or @entity1 with larger breasts (irrespective of the body mass index) were less likely to undergo @entity0 . In order to be in line with the @entity1 's desire, the surgeons of our unit should broaden their indications of @entity0 . The lack of reconstruction of large breasts should certainly be compensated in part with the recent development of free tissue transfers in our unit. LEVEL OF EVIDENCE: 3.
