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

Table 5 Summary of percentage of cumulative volume of all nine standardized re-resection margins as compared to the BCS specimen volume, percentage of cumulative 2-dimensional surface area of all nine standardized re-resection margins as compared to the surface area of the BCS specimen, and percentage of cumulative 2-dimensional surface area of all nine standardized re-resection margins as compared to the surface area of the BCS specimen minus the surface area of the overlying skin ellipse from the pathology report of the 204 BCS cases

Variables	Percentage (range)
Percentage of cumulative volume of all nine standardized re-resection margins as compared to the BCS specimen volume	26.8% (3.5% – 85.7%)
Percentage of cumulative 2-dimensional surface area of all nine standardized re-resection margins as compared to the surface area of the BCS specimen	32.6% (7.5% – 96.3%)
Percentage of cumulative 2-dimensional surface area of all nine standardized re-resection margins as compared to the surface area of the BCS specimen
minus the surface area of the overlying skin ellipse	34.9% (8.1% – 98.2%)
