Current methods for targeting radiation in the breast can overestimate the volume of tissue that needs treatment, which can lead to poor cosmetic results and inadvertent exposure of adjacent normal tissues to radiation. The device used in the current study is sutured directly to the tumor resection site, which helps to address these issues. Cosmetic results for patients implanted with the marker were noted to be excellent. In all patients, the BioZorb marker remained at the site of surgery with no evidence of migration and there were no infections or device-related complications.
The new device's unique open-spiral design incorporates six permanent titanium clips in a fixed 3D array and provides specific landmarks at the site of the excised tumor. This allows the surgeon to secure the device to adjacent tissue and use it for oncoplastic reconstruction prior to its use in radiation treatment planning. Oncoplastic surgery combines plastic surgery techniques with surgical oncology methods, to help maintain the treated breast's natural shape and contour.

"The BioZorb marker is an important advance for breast cancer patients," noted Dr. Kuske. "It allows the surgeon to communicate visually with the radiation oncologist and outline exactly where the tumor was removed. We've never seen anything like it and it's simple but revolutionary."
The device has been used successfully in both the U.S. and New Zealand. It is made of a bioabsorbable material commonly used in other medical devices, allowing the patient's body to absorb the material slowly over time.
The findings of the study presented at the SIS World Congress are consistent with previous research presented at other conferences. The SIS meeting was held Oct. 16-19 in Orlando, Fla.

About Focal Therapeutics
Focal Therapeutics is a medical device company based in Aliso Viejo, Calif. The company developed and manufactures BioZorb, a proprietary bioabsorbable device that provides radiographic marking of soft tissue sites. The BioZorb device is placed at the time of surgical removal of tissue, such as during breast surgery, and the device's three-dimensional array of marker elements has unique clinical utility for patient imaging.
