Minimal Rectal Toxicity in the Setting of Comorbid Crohn’s Disease Following Prostate Cancer Radiotherapy with a Hydrogel Rectal Spacer
We present one of the first cases of a prostate cancer (PCa) patient with inflammatory bowel disease (IBD) treated with intensity-modulated radiotherapy (IMRT) and a hydrogel rectal spacer. A 73-year-old male with a past medical history significant for Crohn's disease (CD) and the recent diagnosis of T1cN0M0 high-risk PCa was referred for definitive radiotherapy. Given the patient's history of ...
متن کاملFirst report of transperineal polyethylene glycol hydrogel spacer use to curtail rectal radiation dose after permanent iodine-125 prostate brachytherapy.
PURPOSE To demonstrate the feasibility of transperineal polyethylene glycol (PEG) hydrogel insertion into anterior perirectal fat for reducing rectal radiation dose in patients with suboptimal rectal dosimetry after permanent iodine-125 prostate brachytherapy. METHODS AND MATERIALS Five patients with suboptimal rectal dosimetry after iodine-125 seed brachytherapy implant underwent a single tr...

15 صفحه اولRectal dose to prostate cancer patients treated with proton therapy with or without rectal spacer
The purpose of this study was to evaluate whether a spacer inserted in the prerectal space could reduce modeled rectal dose and toxicity rates for patients with prostate cancer treated in silico with pencil beam scanning (PBS) proton therapy. A total of 20 patients were included in this study who received photon therapy (12 with rectal spacer (DuraSeal™ gel) and 8 without). Two PBS treatment pl...
