Outcomes of Women Undergoing Mastectomy for Unilateral Breast Cancer Who Elect to Undergo Contralateral Mastectomy for Symmetry: A Systematic Review

BACKGROUND: Breast reconstruction (BR) is routinely offered to restore symmetry after mastectomy for breast cancer. Not all women, however, may want reconstructive surgery.

Sumario:BACKGROUND: Breast reconstruction (BR) is routinely offered to restore symmetry after mastectomy for breast cancer. Not all women, however, may want reconstructive surgery. A contralateral mastectomy (CM) to achieve “flat symmetry” can be an excellent alternative, but surgeons are often reluctant to offer this procedure. This systematic review aimed to summarize the available evidence regarding the outcomes of CM as the first step to developing guidelines in this area. METHODS: PubMed, MEDLINE, CINAHL and PsycINFO were searched to identify primary research studies, published in English between 1 January 2000 and 30 August 2022, evaluating clinical or patient-reported outcomes for women who underwent a CM without reconstruction after a mastectomy for unilateral breast cancer. Simple descriptive statistics summarized quantitative data, and content analysis was used for qualitative data. RESULTS: The study included 15 studies (13 quantitative, 1 qualitative, and 1 mixed-methods) evaluating outcomes for at least 1954 women who underwent a bilateral mastectomy without reconstruction (BM) after unilateral breast cancer. The risk of surgical complications after BM was higher than after unilateral mastectomy without reconstruction (UM) but significantly less than after BR. Satisfaction with the decision for BM was high in all the studies. Key themes relating to flat denial, stigma, and gender-based assumptions were identified. CONCLUSION: Women electing to undergo BM reported high levels of satisfaction with their decision and complication rates similar to those for UM. Further study is needed to comprehensively explore the outcomes for women seeking BM, but these data should give surgeons confidence to offer the procedure as an alternative option for symmetry after unilateral mastectomy for breast cancer. Registration: This systematic review was prospectively registered on the PROSPERO database (CRD42022353689).
