Randomized Prospective Trial of Breast Cancer Locator Guided vs. Wire Localized Partial Mastectomy for Breast Cancer
The BCL System is intended to be used to guide a surgeon when performing partial mastectomy for breast cancer and to minimize positive margins. The purpose of this study is to provide evidence that the BCL is safe, effective, and non-inferior to the standard of care (WL) in the removal of non-palpable invasive breast cancer and DCIS. Investigators in the intervention group will be provided with a three dimensional (3D) image of the cancer in the breast which allows them to visualize the closest distance from the tumor to the skin and the chest wall and quantifies those distances. Investigators will also use a BCL, which is a patient specific, plastic, bra-like form that is transiently placed on the breast prior to surgery and allows the Investigator to mark the projected edges of the tumor on the breast skin and to place bracketing wires inside the breast which define the center of the cancer and distances 1 cm from the tumor edges defined by pre-operative supine MRI.
Primary objective: 1. To provide evidence that the positive margin rate following BCS using the BCL is not inferior to the standard of care (WL) for surgical guidance. Secondary Objectives: 1. To compare the specimen volumes for women randomized to BCL or WL guided BCS. 2. To compare the re-excision rate for women randomized to BCL or WL guided BCS. 3. To compare the cancer localization rate for women randomized to BCL or WL guided BCS. 4. To compare the operative times for women randomized to BCL or WL guided BCS.
