Table 10 Concordance or disconcordance of the spatial location of a positive re-resection margin specimen in comparison to the margin status of the corresponding spatial location on each of the 11 cases in which the BCS specimen had at least one positive/close margin and there was also a positive re-resection margin

From: Standardized and reproducible methodology for the comprehensive and systematic assessment of surgical resection margins during breast-conserving surgery for invasive breast cancer
