Five-year results of post-prostatectomy patients administered a hydrogel rectal spacer implant in conjunction with dose escalated external beam radiation therapy

Objective This study reports on the 5-year biochemical-relapse free survival (bRFS), and late gastrointestinal (GI) and genitourinary (GU) toxicities of patients who underwent a prostatectomy and received high dose (> 72 Gy) radiation therapy with an absorbable polyethylene glycol (PEG) rectal spacer implant.
