A Trial of RSL Versus WL for Malignant Breast Disease

Not Applicable
Completed
Conditions
Breast- Female
Interventions
Procedure: Radioactive Seed Localization
Procedure: Wire Localization
Registration Number
NCT02522468
Lead Sponsor
Wake Forest University Health Sciences
Brief Summary

The purpose of this randomized trial is to determine the superiority of utilizing radioactive seed localization (RSL) over wire-guided localization (WL) for palpable or non-palpable malignant lesions in patients undergoing breast conservation surgery (BCS).

Detailed Description

Consented and eligible subjects will be randomized to either radioactive seed localization or wire localization and stratified by surgeon and invasive versus DCIS prior to localization. Subjects on both arms will undergo breast conservation surgery including surgical specimen removal. Specimens will be grossed according to standard of care procedures. Localization, breast conservation surgery, and post-operative appointments will follow standard of care guidelines. Surveys will be administered according to the study calendar to the radiologist, surgeon, pathologist, and subject for data collection.

Primary Outcome Measures

The primary objective for this study will be the comparison between Radioactive Seed Localization (RSL) and Wire-Guided Localization (WL) based on negative margins in malignant breast disease. This is defined as no tumor on ink in invasive disease and greater than or equal to 2mm from the inked margin in non-invasive disease (DCIS).
