Women who undergo surgery for breast cancer followed by radiation therapy often experience breast deformities that can only be corrected through reconstructive surgery.
Researchers at the McGowan Institute for Regenerative Medicine, in collaboration with bioengineers at Carnegie Mellon University, have developed a polymer-based therapy for breast cancer that could serve as an artificial tissue filler after surgery and a clinically effective therapy.
"Although radiation therapy is the standard treatment for breast cancer following surgery, it is expensive, time consuming and increases the cosmetic deformity caused by surgery," said Howard D. Edington, M.D., associate professor of surgery and surgical oncology at the University of Pittsburgh and faculty member at McGowan. "We sought to develop a possible alternative to radiation therapy that would not only release chemotherapy slowly to kill the cancerous cells left behind after surgery but that also would fill in the dimples and sometimes quite significant indentations that are common after breast surgery and radiation."
