Clinicopathological Factors Affecting Positive Margins after Breast-Conserving Surgery: A Comparative Study of Low- and High-Volume Hospitals

Positive margin rate after BCS was low, with 8.0% among all cases and varied significantly between the hospitals. Patient-, tumor-, radiological-, and surgery-related factors may contribute to these variations. An optimized collaborative multidisciplinary approach to breast cancer care, particularly between radiologists and surgeons, should be strived to achieve improved oncological outcomes in women after BCS.
