This study is a pilot study of the CivaSheet, a new type of intraoperative radiation therapy
(IORT) device that offers several advantages over existing techniques of performing IORT. The
CivaSheet device in this study is already approved by the FDA and is not an experimental
device. This study will allow us to determine how feasible it is to implant the CivaSheet
into patients undergoing surgery for abdominal and pelvic tumors, and assess any possible
side effects of the device. This study, if successful, may allow us to offer the CivaSheet
more widely as treatment option to future patients.
