A retrospective study reported about the benefits and late toxicity following an injection of a hydrogel spacer (HS) between the prostate and rectum for men treated with radiotherapy.
The study, which included 76 men with a clinical stage of T1-T3a prostate cancer underwent general anesthesia for fiducial marker insertion plus injection of the Hydrogel Spacer (HS) into the peri-rectal space before intensity modulated radiation therapy (IMRT) or volumetric modulated radiation therapy (VMAT). The researchers evaluated the safety, benefits and the immediate to long-term effects of gastrointestinal toxicity.
HS is used to move the rectum away from the prostate gland with the goal of limiting any damage to the rectum from “stray” radiation.
They concluded that injection of HS resulted in a reduction of irradiated rectal dose volumes along with minimal GI toxicities; irrespective of prostate size
