Occurrence of Residual Cancer Within Re-excisions After Subcutaneous Mastectomy of Invasive Breast Cancer and Ductal Carcinoma - A Retrospective Analysis.

Background/aim: Surgical margin status remains an important determinant for recurrence of invasive breast cancer and ductal carcinoma in situ. We compared the number of positive margins in initial histology with rates of residual tumor in re-excision specimens. Furthermore, we analysed cost-effectiveness of re-excisions.
