Surgical and Oncologic Impact of Cavity Shave Margins in Breast-Conserving Surgery.
Cavity shave margins cut re-excision for positive margins in breast-conserving surgery.
Surgical and Oncologic Impact of Cavity Shave Margins in Breast-Conserving Surgery.
Surgical margin status is a critical determinant of local control in breast-conserving surgery (breast-conserving surgery).
Were stratified according to operative technique into those undergoing breast-conserving surgery with circumferential cavity shave margins and those undergoing breast-conserving surgery without (non-cavity shave margins).
re-excision for positive margins dropped sharply with cavity shave margins
A total of 2,648 patients met inclusion criteria, including 1762 (66.5%) treated with non-cavity shave margins and 886 (33.5%) with cavity shave margins.
Overall, 122 relapses (4.6%) were documented.
Recurrence was observed in 3.5% of patients undergoing cavity shave margins and 5.2% treated with non-cavity shave margins, although this difference did not reach statistical significance (p = 0.067).
Although cavity shave margins was not independently associated with recurrence after adjustment, routine cavity shave margins substantially reduced re-excision for positive margins.
Reducing the need for subsequent surgical procedures may lessen patient burden while improving healthcare utilization and lowering associated costs, supporting cavity shave margins as a valuable strategy in contemporary breast-conserving surgery.
