Quadrant High Dose Rate Intraoperative Radiation Therapy (IORT) for Early-Stage Breast Cancer: A Pilot Study

This study was started to validate the possibility of administering radiation therapy during surgery to the tissue surrounding the tumor once the tumor has been removed. This surrounding breast tissue is at greater risk for developing breast recurrences. This treatment may be as effective as the conventional 5-6week radiation treatment in reducing the risk of further local recurrences after breast-conserving surgery. Through this study, we would like to confirm that this procedure is a safe alternative to conventional breast radiation, with no additional side effects when compared with the conventional surgery and radiation therapy.
