Efficacy of OneMark Device in Identifying Breast Cancer for Surgery and Surveillance
Sponsor:

University of California, San Diego

Information provided by (Responsible Party):

Sara Grossi

Brief Summary:

The goal of this research is to study a localization device for breast cancer called OneMark. This device will be studied in breast cancer surgery and during surveillance in patients being monitored for breast cancer. The main questions the study aims to answer are: Can surgeons visualize the OneMark device during breast cancer surgery better than a standard of care visualization device? Can radiologists visualize the OneMark device over time during breast cancer surveillance in patients with low or high density breast tissue? Participants will undergo breast cancer surgery or surveillance as required for their regular care. For patients undergoing surgery, the device will be implanted ahead of surgery. For patients in surveillance, the device will be implanted during biopsy and visibility of the device will be assessed by radiologists after 1, 3, and 6 months, and optionally after 12 months. Surgeons will complete a questionnaire at every surgery on the visibility of the OneMark device and the standard of care visualization device. Radiologists will complete a questionnaire after 1, 3, 6 months (and optionally after 12 months) after implantations in the patients in the surveillance program.

Detailed Description:

This is a prospective, open-label, single-site study to evaluate the OneMark visualization device in 2 patient populations: patients with breast cancer undergoing resection surgery, and patient at high risk of breast cancer in a surveillance program. In addition, the study enrolls 2 physician populations: surgeons and radiologists specialized in breast cancer. In the surgery cohort, the investigators will compare the OneMark device to the standard of care wireless localization system, SAVI SCOUT. The visibility of the two devices will be evaluated before, during, and after surgery (ex vivo). In the surveillance cohort, the investigators will evaluate the detectability over time of the OneMark device placed as fiducial during breast biopsy in patients with low or high density breast tissue. If participants in the surveillance group will require surgery during the study, the surgeons can opt to place a SAVI SCOUT marker and will evaluate the visibility of both devices like in the cohort described above. We hypothesize that the OneMark device has superior intra-operative visibility compared to the SAVI SCOUT system for detection of breast cancer for surgical resection. We also hypothesize that, when the OneMark device is used as fiducial during surveillance, it will be visible over time.
