Oncoplastic level II volume displacement surgery for breast cancer: oncological and aesthetic outcomes

Abstract

AbstractOncoplastic breast-conserving surgery (OBCS) is increasingly used to treat breast cancer with the dual purpose of performing a radical oncological resection while minimizing the risk of post-operative deformities. The aim of the study was to evaluate the patient outcomes after Level II OBCS as regards oncological safety and patient satisfaction. Between 2015 and 2020, a cohort of 109 women consecutively underwent treatment for breast cancer with bilateral oncoplastic breast-conserving volume displacement surgery; patient satisfaction was measured with BREAST-Q questionnaire. The 5-year overall survival and disease-free survival were 97% (95%CI 92, 100) and 94% (95%CI 90, 99), respectively. In two patients (1.8%), mastectomy was finally performed due to margin involvement. The median patient-reported score for “satisfaction with breast” (BREAST-Q) was 74/100. Factors associated with a lower aesthetic satisfaction index included: location of tumour in central quadrant (p = 0.007); triple negative breast cancer (p = 0.045), and re-intervention (p = 0.044). OBCS represents a valid option in terms of oncological outcomes for patients otherwise candidate to more extensive breast conserving surgery; the high satisfaction index also suggests a superiority in terms of aesthetic outcomes.
