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 (p=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 in situ 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.
