Trends and Perspectives in Oncoplastic Breast Surgery: Findings From a Web-Based Survey With the Korean Breast Cancer Society.

Purpose: Oncoplastic breast surgery (OPS) is a crucial component of breast cancer surgery that combines oncological safety with improved cosmetic outcomes. OPS is increasingly being adopted worldwide, although the techniques and concepts vary based on patient demographics and surgeons' expertise. This study aimed to evaluate the evolving OPS concept among Korean breast surgeons and assess the current trends in OPS techniques.

Methods: A web-based survey was conducted among members of the Korean Breast Cancer Society and Korean Oncoplastic Breast Surgery Study Group. The questionnaire included seven questions that explored opinions on the scope and practical trends of OPS. Respondents were stratified according to hospital type, position, and age. Data were analyzed to identify trends and differences based on demographic factors.

Results: A total of 122 surgeons responded, with a majority (78.7%) working in academic or tertiary hospitals. Most respondents (77.9%) considered OPS to include volume displacement/replacement and implant-based reconstruction, regardless of the resection volume. In addition, 70.5% agreed that robotic or endoscopic surgery fell within the scope of the OPS. Autologous reconstruction after a partial mastectomy is preferred for achieving excellent cosmetic results, particularly among younger surgeons. Notably, 59.0% of the surgeons reported using single- and dual-surgeon strategies.

Conclusion: OPS is widely practiced among Korean breast surgeons, with the increasing adoption of advanced techniques such as robotic-assisted and endoscopic surgery. Although preferences differ with the surgeon's age, the concept of OPS has expanded considerably, and a multidisciplinary approach remains critical. Understanding these trends is essential to optimize patient care and improve surgical training programs.
