The Practice Patterns and Perceptions of Korean Surgeons Regarding Margin Status after Breast-Conserving Surgery

چکیده
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.

Atypical Ductal Hyperplasia at the Margin of Lumpectomy Performed for Early Stage Breast Cancer: Is there Enough Evidence to Formulate Guidelines?
Background. Negative margins are associated with a reduced risk of ipsilateral breast tumor recurrence (IBTR) in women with early stage breast cancer treated with breast conserving surgery (BCS). Not infrequently, atypical ductal hyperplasia (ADH) is reported as involving the margin of a BCS specimen, and there is no consensus among surgeons or pathologists on how to approach this diagnosis res...
متن کاملTechnical factors, surgeon case volume and positive margin rates after breast conservation surgery for early-stage breast cancer.
BACKGROUND For patients with breast cancer, a negative surgical margin at first breast-conserving surgery (BCS) minimizes the need for reoperation and likely reduces postoperative anxiety. We assessed technical factors, surgeon and hospital case volume and margin status after BCS in early-stage breast cancer. METHODS We performed a retrospective cohort study using a regional cancer centre dat...

BACKGROUND The high incidence of ductal carcinoma in situ (DCIS) and variations in its treatment motivate inquiry into the comparative effectiveness of treatment options. Few such comparative effectiveness studies of DCIS, however, have been performed with detailed information on clinical and treatment attributes. METHODS We collected detailed clinical, nonclinical, pathological, treatment, a...

PURPOSE We evaluated the effect of positive superficial and/or deep margin status on local recurrence (LR) in invasive breast cancer treated with breast-conserving surgery (BCS) followed by radiotherapy. MATERIALS AND METHODS In total, 3,403 stage 1 and 2 invasive breast cancer patients treated with BCS followed by radiotherapy from January 2000 to December 2008 were included in this study. T...
