Objective Over the past decade, China has seen rapid development and significant achievements in the field of oncoplastic breast surgery. To understand our current academic standing and further the high-quality development of oncoplastic breast surgery in China, the Committee of Oncoplastic Surgery and Committee of Integrated Nursing for Breast Reconstruction (COPS and CINBR, respectively), under the China Anti-Cancer Association (CACA), conducted a cross-sectional study in 2023.

Methods  The cross-sectional study assessed the current state of technological advancements and decision-making factors among member hospitals of COPS and CINBR within the year 2022 using an electronicquestionnaire.The results were analyzed by χ² test or Fisher's precision probability test, multiple response analysis and displayed by Pareto chart.

Results Among the 195 participating hospitals, 165 hospitals (84.6%) had performed oncoplastic breast surgery, including 42hospitals (21.5%) which reported an adoption rateof oncoplastic proceduresover 50%. Meanwhile, 166 hospitals (85.1%) already introduced the immediate breast reconstruction into their clinical practice, indicating that the popularization of the concepts and techniques in oncoplastic breast surgery had significantly improved. The adoption rates of nipple reconstruction (173/195, 88.7%) and revision procedures(167/195, 85.6%) were less than 10%, suggesting that low prevalence of those procedures after breast reconstruction still require attention. Factors including geographic location (multivariate Logistic regression analysis, P<0.05), hospital grade and size (multivariate Logistic regression analysis, P<0.05), and patient preferences(multiple response analysis: popularity rate > 90%, response rate > 30%) significantly influence the adoption of oncoplastic breast surgery and decisions regarding breast conservation or reconstruction.

Conclusions Although increased attention on the oncoplastic breast surgeryhas been paid in China, the prevalence and innovation ability of oncoplastic breast surgerystill need further improvement. This research offers crucial evidence-based insightsforfuture policy-making and academic planning by CACA andothergovernmentalagencies.
