- Introduction: Oncoplastic breast surgery (OBS) has been implemented with increasing frequency in the treatment of breast cancer. The aim of this study was to compare the oncologic outcome after OBS to the outcome after conventional breast-conserving surgery (BCS) in patients with invasive breast cancer. Patients and Methods: In all, 197 patients treated with OBS were compared to 1399 patients treated with conventional BCS from 2008 to 2013. We evaluated nonradical primary tumor excision, time to initiation of adjuvant therapy, disease-free survival (risk of recurrent disease), and survival (cause specific and overall). Identification of patients and follow-up were made using the Danish Breast Cancer Cooperative Group registry and the Danish Cause of Death registry. Multivariate logistic regression and the Cox proportional hazard analysis were used to obtain odds ratios and hazard ratios with 95% confidence intervals (CI). Results: There was a lower risk for nonradical primary tumor excision for patients undergoing OBS versus conventional BCS (adjusted odds ratio:95% CI, 0.50:0.29-0.84). No significant differences were found with regard to a delay in initiation of adjuvant chemotherapy (adjusted hazard ratio:95% CI, 1.14:0.89-1.45) or radiotherapy (0.91:0.71-1.16), disease-free survival (1.23:0.61-2.47), breast cancer as cause of death (1.46:0.52-4.09), breast cancer as underlying or multiple cause of death (0.90:0.34-2.37), or overall survival (0.90:0.51-1.60). Conclusion: We found no significant differences in oncologic outcome comparing OBS to conventional BCS. However, a lower risk of nonradical primary tumor excision was found for patients treated with OBS. These results indicate that OBS is a safe procedure.

- Introduction: Oncoplastic breast surgery (OBS) has developed as an extension of breast-conserving surgery (BCS) in an effort to improve esthetic and functional outcome following surgery for breast cancer. The aim of the present study was to evaluate the possible benefits of OBS, as compared with BCS, with regard to health-related quality of life (HRQoL), using patient-reported outcome measures (PROMs). Patients and methods: Patients treated with OBS (n = 200) and BCS (n = 1304) in the period 1 January 2008 to 31 December 2013 were identified in a research database and in the Danish Breast Cancer Cooperative Group (DBCG) registry. Data on patient, tumor, and treatment characteristics were retrieved from the DBCG registry. Patients were sent a survey including the Breast-Q™ BCT postoperative module and a study-specific questionnaire (SSQ) in 2016. A good outcome in the Breast-Q module was defined as above the median. OBS was compared to BCS using a logistic regression analysis, and then adjusted for potential confounders, yielding odds ratios (OR) with 95% confidence intervals. Results: There was a statistically significant better outcome considering the HRQoL domain “Psychosocial Well-being “ for patients treated with OBS as compared with BCS (OR 2.15: 1.25–3.69). No statistically significant differences were found for the domains “Physical Well-being” (0.83: 0.50–1.39), “Satisfaction with Breast” (0.95: 0.57–1.59), or “Sexual Well-being” (1.42: 0.78–2.58). Conclusion: The present study indicates better outcomes of HRQoL for breast cancer patients treated with OBS as compared to patients treated with BCS. There was no increase in physical discomfort among OBS patients despite more extensive surgery.
