Dr. Neil Mariados discusses Minimizing Radiation Therapy Side Effects on the BackTable 108 Podcast

Dr. Neil Mariados

Dr. Neil Mariados is the medical director of radiation oncology with Associated Medical Professionals in Syracuse, New York.

Dr. Dan Welchons discusses Minimizing Radiation Therapy Side Effects on the BackTable 108 Podcast

Dr. Dan Welchons

Dr. Daniel Welchons is a principal physician and managing partner at Associated Medical Professionals of NY in New York.

Synopsis

First, Dr. Mariados explains the need for rectal spacing in order to minimize the toxicities of prostate radiation. He then discusses the national rectal spacing trials (SpaceOAR and Barrigel) that he and Dr. Welchons participated in. The doctors also mention that most patients are interested in rectal spacing in order to minimize toxicities, but having a tumor with extracapsular extension is a contraindication of the procedure.

Then, the doctors compare two rectal spacing products, SpaceOAR and Barrigel, in the context of setup and product materials. They explain the Barrigel technique, which is performed through the transperineal approach. Preoperatively, their patients receive Valium and oxycodone. After the surgery, the spacer can be visualized through a CT scan. Dr. Welchon also reflects on his process of learning the Barrigel procedure and the satisfaction that comes with helping patients avoid toxicities.

The stability of Barrigel is 1 year. Most patients feel little to no discomfort after the procedure, and the doctors do not prescribe any postoperative antibiotics. The most serious complication of rectal wall spacing is rectal wall invasion, which occurs after incorrect product placement. However, the doctors discuss ways to avoid this complication, like using tactile feedback. They also emphasize the similarities between rectal spacing technique and transperineal prostate biopsies. Finally, they emphasize the importance of publications and education to avoid misunderstanding and myths about rectal spacing.
