Spontaneous healing of rectal penetration by SpaceOAR ® hydrogel insertion during permanent iodine-125 implant brachytherapy: A case report.

Spontaneous healing of rectal penetration by SpaceOAR® hydrogel insertion during permanent iodine-125 implant brachytherapy: A case report. Mol Clin Oncol. 2019 Dec;11(6):580-582 Authors: Iinuma K, Mizutani K, Kato T, Nakane K, Tanaka H, Nakano M, Matsuo M, Koie T Abstract Radiation therapy with permanent iodine-125 implant brachytherapy is well established for curable prostate cancer. To maximize the therapeutic potential of brachytherapy, delivered radiation doses have been increased accompanied by refined intraoperative procedures of radioactive seeds placement. However, dose escalation is a double-edged sword in prostate brachytherapy; it could induce rectal toxicity, yet is successful in curable treatment in prostate cancer. To reduce irradiation of the rectum, the SpaceOAR® system has been used to inject synthetic polyethylene glycol hydrogel between the prostate and the rectum. The present report describes a case of spontaneous healing of rectal penetration associated with SpaceOAR® hydrogel. PMID: 31692963 [PubMed]
