Published
High-dose-rate brachytherapy combined with external beam radiotherapy was an effective and safe treatment for localized prostate cancer. Combination of long-term ADT was suggested to be necessary, even for HDR brachytherapy, and was useful in suppressing late toxicities. Meanwhile, pelvic irradiation was suggested to have an adverse effect on OS of our study population.
