Breast Cancer Patients Undergo First Combined Use of Electron Beam Boost Therapy with Tumor Removal During Surgery.Doctors at St. Joseph Hospital First to Use Electron Beam A stream of electrons, or electricity, that is directed towards a receiving object.

Radiation Boost Therapy in the Operating Suite, Reducing Overall Time Needed for Post-Operative Radiation Therapy for Breast Cancer Patients ORANGE, Calif. -- Breast cancer surgeons and radiation oncologists at St. Joseph Hospital in Orange performed a new procedure combining removal of a patient's breast tumor with the power of electron beam radiation in the operating room operating room n.

Traditionally, after surgical removal of the breast cancer, many patients undergo radiation therapy for about six weeks followed by an additional five days of focused radiation treatment, called a "boost." It is the first time on the West Coast that electron beam radiation treatment was used as an electron boost during breast cancer surgery. This procedure, known as intraoperative radiation therapy intraoperative radiation therapy Radiation oncology RT directly in a tumor during surgery. See Radiation oncology. (IORT IORT Intraoperative Radiotherapy (oncology) ), was delivered with the FDA-approved device, the Mobetron([R]). "We are extremely excited to see St. Joseph's begin treating breast cancer with the Mobetron([R])," noted John Powers The name John Powers can refer to:

This also results in substantially less radiation affecting the healthy tissue of the breast and skin. By harnessing the power of Mobetron's([R]) therapeutic electron beam during surgery, doctors can decrease the number of radiation treatments a patient would typically undergo following surgery. "Our hope with this new technology is to reduce the breast cancer patient's overall treatment time while improving the outcome," said Jay K. Harness, M.D., a breast cancer surgeon at St. Joseph Hospital and a former president of the American Society of Breast Surgeons. "I am excited about the future of this technology as we begin to expand its use in breast cancer patients as well as other cancers in the future." |
