Increasing incidence of bilateral mastectomies: the patient perspective.

ABSTRACT

BACKGROUND: Numerous studies have reported increasing rates of contralateral prophylactic mastectomies (CPMs). Understanding patient rationale for the surgical choice may provide insight into this trend. METHODS: A questionnaire was mailed to 350 mastectomy patients identified from a community health system tumor registry. RESULTS: Two hundred fifty questionnaires were received; of these, 237 had undergone mastectomy. Fifty-two percent had unilateral mastectomy (UM), and 43% had bilateral mastectomies (BMs) (6% for bilateral disease). Women younger than 60 years of age were more likely to choose BM (P = .0046). Those who had CPM were significantly more likely to make the same surgical decision (P < .0001). Reconstruction was performed in 52%, with BM patients more likely to undergo reconstruction (P = .009). Twenty-three (19%) needed unanticipated reoperation for reconstruction complications. CPM had equivalent rates of unanticipated surgery versus UM (P = .64). CONCLUSIONS: Patients choosing BMs are younger, have equivalent rates of reoperation because of reconstruction complications, and are significantly more satisfied with their decision than those who chose UM.
