Safety of Dose Escalation in Definitive Hypofractionated Radiation Therapy With SPACEOAR TM for Patients With Low-to-intermediate Risk Localized Prostate Cancer (DESAR-L)
A single institution with a single group, a phase II study, low- and medium-risk studies performed after biodegradable substance injection prostate cancer dosage increase. The investigator plans to evaluate grade 1 or higher rectal bleeding occurring within 3 years in patients who have received low -fractionation curative radiotherapy.
