Prostate-specific antigen density is predictive of outcome in suboptimal prostate seed brachytherapy

摘要

PURPOSE: In prostate seed brachytherapy, a D-90 of <130 Gy is an accepted predictive factor for biochemical failure (BF). We studied whether there is a subpopulation that does not need additional treatment after a suboptimal permanent seed brachytherapy implantation.
