DuraSeal® as a spacer to reduce rectal doses in low-dose rate brachytherapy for prostate cancer

The purpose of this study was to evaluate the utility of off-label use of DuraSeal® polyethylene glycol (PEG) gel in low-dose rate (LDR) prostate brachytherapy seed implantation to reduce rectal doses. Diluted DuraSeal® was easy to use and, in spite of a clearance effect, useful in decreasing D2cc rectal doses.
