Introduction: The NABON Breast Cancer Audit showed that more than 70% of the Dutch women undergoing surgery for breast cancer maintained their breast contour by breast-conserving surgery (BCS) or by immediate reconstruction after ablative surgery. The proportion of oncoplastic surgery applied in patients undergoing breast-conserving treatment remains unknown. The aim of our study was to assess the need for standardization of oncoplastic breast-conserving surgery (OPBCS) in an attempt to enable measurement of the quality of OPBCS. Methods: To gain a better understanding of current practice in OPBCS, we sent a questionnaire to all breast surgeons in The Netherlands who are members of the breast surgery working group (n = 134). Results: A total of 60 breast surgeons, representing different hospitals in The Netherlands, responded. 61.7% of the breast surgeons performed BCS on 60–100% of their patients. 68.3% responded that BCS was performed using OPS techniques in up to 40% of their patients. OPBCS was defined as level I volume displacement by 45.2% of the breast surgeons and as BCS performed by a breast surgeon and plastic surgeon together by 32.3% of the breast surgeons. 94.5% indicated that there is a need for standardization of the definition of OPBCS in The Netherlands. Conclusion: This study demonstrates that OPBCS is a major part of daily clinical practice of Dutch breast surgeons treating BC patients. Despite this, there is no clear definition of OPS in breast-conserving treatment in The Netherlands. Only after standardization can a classification code and quality indicator be initiated for OPBCS. Ultimately, this will facilitate improvement in quality of BC care.
