Brief Summary:
Our objective is to determine whether the Breast Cancer Locator (BCL) can safely and effectively localize breast cancers in patients treated at locations distant from the site of BCL manufacture. This information will be transmitted to CairnSurgical, Inc. where the BCL will be fabricated, tested for quality assurance, sterilized and shipped to the patient's surgeon. The surgeon will then utilize the BCL at the time of resection of the palpable breast cancer.

Condition or disease Intervention/treatment Phase
Palpable Breast Cancer Device: Breast Cancer Locator (BCL) Not Applicable

Detailed Description:

The primary purpose of the study is to determine whether a device called the Breast Cancer Locator (BCL) accurately identifies the location of cancer in the breast. The Breast Cancer Locator is a plastic bra-like form that gives the surgeon information about the location of the cancer in the breast. The location information is derived from an MRI which is obtained with the patient lying flat on their back (just as they are on an operating room table). The BCL is then custom made for the patient using 3D printing technology.

The cancer can be felt by the surgeon, and the surgeon will remove the cancer by feeling the edges of it as the surgeon would normally. Since the cancer can be felt, the surgeon does not need an image guidance system such as the BCL to locate the cancer in the breast. Other women may have breast cancers that cannot be felt identified by mammography or MRI. If the BCL proves to accurately localize breast cancer, it may be a useful guide for the surgeon for these other women.

Additionally, we want to determine whether this technology can be successfully employed at multiple sites and what, if any, complications occur during surgery as a result of using this device. The BCL has been used in 19 patients at Dartmouth with no complications.

Arm Intervention/treatment
Experimental: Breast Cancer Locator (BCL)
The Breast Cancer Locator (BCL) uses 3D printing to create a bra-like plastic form that matches the breast surface when the patient is in the supine MRI (and surgical) position. This locator will be constructed pre-operatively, sterilized and provided to the surgeon at the time of procedure.
Device: Breast Cancer Locator (BCL)
This locator will be constructed pre-operatively, sterilized and provided to the surgeon at the time of procedure. The outline of the breast cancer on the breast surface at the point where the cancer is closest to the skin is built into the locator, so that the surgeon can simply apply the locator to the patient's breast and trace the tumor outline on the skin.




Primary Outcome Measures :
  1. Determine the proportion of patients who will have had the localization wire deployed within the cancer on the specimen mammogram. [ Time Frame: 30 Days ]

Secondary Outcome Measures :
  1. Whether the study Radiologist can accurately segment the tumor from the supine MRI images that are provided. [ Time Frame: 30 Days ]
  2. Time from supine MRI to delivery of the BCL to the surgeon. [ Time Frame: 30 Days ]
  3. Whether the BCL enabled the surgeon to successfully place all surgical cues in/on the breast (tumor edges, blue dye injections and hook wire placement). [ Time Frame: 30 Days ]
  4. Lumpectomy specimen volumes. [ Time Frame: 30 Days ]
  5. Operative times. [ Time Frame: 30 Days ]
  6. The pathologic tumor margins (distance from the tumor to the specimen edge). [ Time Frame: 30 Days ]
  7. Complications from surgery. [ Time Frame: 30 Days ]
  8. Surgeon satisfaction with the technical aspects of surgery guided by the Breast Cancer Locator. [ Time Frame: 30 days ]
