Patient Satisfaction Following Level II Oncoplastic Breast Surgery: A Comparison with Mastectomy Utililizing the Breast-Q Questionnaire will be published in Surgical Oncology.

[INTRODUCTION] Oncoplastic breast surgery (OBS) is increasingly used to decrease the deformity in breast conserving therapy (BCT) for breast cancer. We aimed to evaluate patient reported satisfaction following level II OBS and mastectomy utilizing the BREAST-Q questionnaire.

[METHODS] Patients who underwent level II OBS BCT and those who underwent mastectomies were distributed the BREAST-Q post-reduction/mammoplasty module. Clinicopathological data were collected from review of patient charts. Results were scored using the standardized scoring system (Q-score). Results of the OBS group were compared to those in the mastectomy group.

[RESULTS] A total of 88 patients who underwent level II OBS and 101 patients who underwent mastectomy completed the questionnaire. Mann-Whitney odds estimator demonstrated higher satisfaction with breasts (1.51, 95% CI [1.04-2.25], p = 0.026) and higher psychosocial well-being (1.51, 95% CI [1.04-2.15], p = 0.022) in those who underwent OBS compared to mastectomy.

[CONCLUSION] Results demonstrate a high satisfaction with breasts and improved psychosocial wellbeing in patients who underwent level II OBS compared to those undergoing mastectomy. These results demonstrate that OBS should be considered in patients where mastectomy otherwise would be necessary. Further larger multi-institutional studies are necessary to examine the effect of OBS on the quality of life of breast cancer patients.
