Dr. Hoffman and colleagues have persisted in their efforts to provide a safe, reliable pelvic prosthesis to protect the small bowel during high-dose radiation therapy. I started using this type of plastic device in the early 1980s as part of the management of advanced primary and recurrent rectal cancer.[1,2] Similar to data reported by Drs. Hoffman, Sigurdson, and Eisenberg in this issue, my colleagues and I at the National Cancer Institute also noted a learning curve that accompanied our experience. We reported our experience with two iliac artery fistulas that occurred after extensive radiation therapy, possibly due to the prosthesis.[3] Sepsis within the irradiated field and surrounding the prosthesis led to a prosthesis-related death in one patient. A second patient who had multiple postoperative complications died of a pulmonary embolus.
