Does a Close Surgical Margin for Ductal Carcinoma In Situ Associated with Invasive Breast Carcinoma Affect Breast Cancer Recurrence?

摘要

Purpose: Our aim was to determine if a close surgical margin ( = 2 mm, DCIS as present or absent, extensive intraductal component as yes or no were investigated. All patients were followed-up for IBTR. Results: The median age was 50 years (range, 29-82), and median tumor size was 25 mm (range, 5-50). Median follow-up time was 56 months (range, 12-114). Of the 628 IBC patients, 440 (70%) were found to be associated with DCIS. Of the 440 patients with DCIS, 119 (27%) had a close margin ( = 2 mm for DCIS. Among 440 IBC patients associated with DCIS, there were three local recurrences. One developed in a patient who had a close surgical margin for DCIS, and in the other two patients, surgical margins were >= 2 mm. Conclusions: No ink on tumor is an adequate margin for IBC associated with DCIS in patients who undergo BCT and it is not associated with increased IBTR.
