Summary

This is a prospective study comparing partial mastectomy performed with routine cavity shave margins and Savi Scout® localization to partial mastectomy performed with selective margins and Savi Scout® localization. The primary objective is to determine the difference in positive margin rate between the two methods. The secondary objectives are to determine the differences in the rate of re-excision, volume of tissue extracted and Breast-Q® score between the two methods. It is hypothesized that the Savi Scout® will allow for decreased volume of tissue excised when compared to routine cavity shave margins without any difference in positive margin rate or rate of re-excision.

Conditions

Interventions

PROCEDURE

Arm 1 Partial mastectomy with Savi Scout® localization and shave margins.

Patients will undergo preoperative Savi Scout® reflector placement under image guidance per routine care. Patients will undergo randomization. With Arm 1 randomization, the surgeons will be instructed to perform a partial mastectomy with routine cavity shave margins using Savi Scout® localization. The lesion will be removed in the routine fashion. The surgeons will use the Savi Scout® to perform routine cavity shave margins by extracting superior, lateral, inferior, medial, anterior, and posterior margins.

PROCEDURE

Arm 2 Partial mastectomy with Savi Scout® localization and selective shave margins.

Patients will undergo preoperative Savi Scout® reflector placement under image guidance per routine care. Patients will undergo randomization. With Arm 2 randomization, the surgeons will be instructed to perform a partial mastectomy with selective margins shave margins using Savi Scout®. The lesion will be removed in the routine fashion. The Savi Scout® localizer will be utilized to determine selective shave margins by examining the same margins on the excised tissue specimen. The surgeon will obtain selective margins if the margin of the tissue specimen is within 1mm of invasive cancer and 2mm within DCIS.
