Resection of Cavity Shave Margins in Breast Conserving Surgery

Resection of additional tissue around the tumor cavity significantly reduces the need to return to surgery for margin control.

The need to return to the operating room for positive margins after breast-conserving surgery delays adjuvant therapy, is upsetting to patients, and is expensive for individuals and health systems. Prior, single-center studies have shown that circumferential resection of additional tissue around the tumor cavity (cavity shave margin [CSM]) reduces the rate of positive margins and re-excision in breast cancer patients undergoing partial mastectomy (PM).

To further assess the benefit of CSM resection in this setting, investigators conducted a multicenter, randomized trial in which 400 stage 0–III breast cancer patients undergoing PM were assigned to either have CSM resection (shave group) or not have CSM resection (no shave group). Randomizati…
