Summary

This randomized controlled trial is to evaluate the impact of additional cavity shaving (CS) on pathological cavity margin (CM) status in breast cancer patients. Patients receiving standard breast-conserving surgery (BCS) will be randomized to intra-operative CM assessment versus intra-operative CS followed by CM assessment. The primary objective of this study is to assess the impact of CS on intra-operative CM status, intra-operative re-excision rate, post-operative CM status and re-excision rate, cosmetic outcomes, and on intraoperative time and medical costs.

PROCEDURE

Cavity shaving

Resect the residual cavity circumferentially (superior, inferior, medial, lateral) and the thickness of the cavity shaving depends on the surgeon's discretion (Recommended 0.5-1.0cm). The principles of the cavity shaving includes: 1) do not compromise the cosmetic outcomes; 2) covers the entire cavity;

PROCEDURE

Standardized BCS+CM assessment.

For standardized BCS(Chen K, et al. Ann Surg Oncol. 2012), we resect a rim of 1 cm macroscopically normal tissue around the tumor. The anterior and posterior margins of the tumor-containing specimen extended up to the subdermal plane of the skin and down to the pectoralis major fascia, respectively. The anterior and posterior CMs assessment will not be needed. A surgical blade was used for resecting the CMs (superior, inferior, medial and lateral) to render the thickness of the CMs as thin as possible. No procedures were required for distinguishing the inner and outer surface. They were then frozen and cut parallel, but not perpendicular to the largest surface area. CMs were defined as positive when in situ or invasive carcinoma was found intraoperatively by frozen-section analysis.
