PURPOSE: We sought to explore the correlation between BMI and postoperative sexual function, body image, and breast-specific sensuality before and after breast cancer surgery. METHODS: A cross-sectional survey of patients at least 1 year from surgery employed the Female Sexual Function Index (FSFI) and investigator-generated questions. Patients who underwent lumpectomy (L), mastectomy (M), and mastectomy with reconstruction (MR) were compared across three BMI groups: normal weight, overweight, and obese. RESULTS: Two hundred fifty-five patients underwent lumpectomy (L, n = 174), mastectomy (M, n = 22), or mastectomy with reconstruction (MR, n = 59). Median age was 57 (range 30-93) and median BMI was 28 (range 19-45). Obese and overweight women reported more appearance dissatisfaction (18.1 and 13.0%) than normal weight women (4.1%) (p = 0.01). Lower satisfaction was associated with increasing BMI within the MR group (p = 0.05). The obese group's median FSFI score met criteria for sexual dysfunction (25.90, range 11.30-33.10). More overweight women reported their chest played an important role in intimacy before and after surgery, but a postoperative decline in the importance of this role was observed in all groups. CONCLUSIONS: Greater post-treatment BMI is inversely related to postoperative appearance satisfaction, particularly in those undergoing mastectomy with reconstruction. The role of the breast in intimacy is greatest in overweight women, but decreases postoperatively in all BMI groups. IMPLICATIONS FOR CANCER SURVIVORS: Postoperative appearance satisfaction and sexual function seems to be correlated to post-treatment BMI, which highlights the need to encourage perioperative weight management for improved survivorship outcomes.

BACKGROUND: As mastectomy rates increase and overall survival for early breast cancer improves, a better understanding of the long-term consequences of mastectomy is needed. We sought to explore the correlation of specific mastectomy type with the Female Sexual Function Index (FSFI), body image satisfaction, and the reconstructed breast's role in intimacy. METHODS: This study is a secondary analysis of a cross-sectional survey including a retrospective chart review. Patients at least one year from primary surgery were invited to complete the survey between 2012 and 2014. Baseline characteristics and survey responses were compared between three mastectomy groups: total/modified radical (TMRM), skin-sparing (SSM), and nipple-sparing (NSM). All patients underwent reconstruction. RESULTS: Of 453 invited, 268 (59%) completed the survey. Sixty underwent mastectomy with reconstruction: 16 (27%) TMRM, 36 (60%) SSM, and 8 (13%) NSM. There were no significant differences in median total FSFI scores between groups, yet median FSFI scores for the NSM group indicated sexual dysfunction. After adjusting for receipt of chemotherapy and/or radiation, NSM had the lowest median desire score. There was a trend for the NSM group to be the least satisfied with postoperative appearance, but also more likely to report that the chest was "often" caressed during intimacy. However, nearly 40% of the NSM group reported that caress of the reconstructed breast was unpleasant. CONCLUSION: NSM offers patients the greatest opportunity for preservation of their native skin envelope and potentially enhanced cosmetic outcome, but our results did not demonstrate superior sexual function or body image outcomes in this group. By highlighting surgical consequences of mastectomy preoperatively, surgeons may better set realistic patient expectations regarding both aesthetic and functional outcomes after breast cancer surgery. With clearer expectations, patients will have a better opportunity for improved surgical decision-making.
