Two consecutive surveys for breast surgeons in Korea were conducted to comprehend the practice patterns and perceptions on margin status after breast-conserving surgery. The surveys were conducted online in 2014 (initial) and 2016 (follow-up). A total of 126 and 88 responses were obtained in the initial and follow-up survey, respectively. More than 80% of the respondents replied to routinely apply frozen section biopsy for intraoperative margin assessment in both surveys. Re-excision recommendations of the margin for invasive cancer significantly changed from a close margin to a positive margin over time (=0.033). Most of the respondents (73.8%) defined a negative margin as "no ink on tumor" in invasive cancer, whereas more diverse responses were observed in ductal carcinoma cases. The influence of guideline establishment for negative margins has been identified. A high uptake rate of intraoperative frozen section biopsy was noted and routine use needs reconsideration.
为了解保乳手术后切缘状态的实践模式和认知情况，韩国对乳腺外科医生进行了两次连续调查。调查于2014年（首次）和2016年（随访）通过网络进行。首次调查和随访调查分别获得了126份和88份回复。在两次调查中，超过80%的受访者表示常规应用冰冻切片活检进行术中切缘评估。随着时间推移，浸润性癌切缘再次切除的建议从近切缘显著变为阳性切缘（P=0.033）。大多数受访者（73.8%）将浸润性癌的阴性切缘定义为“肿瘤上无墨水”，而在导管癌病例中观察到更多样化的回答。已确定了阴性切缘指南制定的影响。术中冰冻切片活检的采用率较高，常规使用需要重新考虑。
