A NEW MODEL USING NUMBER OF NEEDLES AND ANDROGEN DEPRIVATION TO PREDICT CHRONIC URINARY TOXICITY FOR HIGH OR LOW DOSE RATE PROSTATE BRACHYTHERAPY

Abstract

HDR and LDR chronic urinary toxicity grade 2 or greater rates were equivalent. However, grade 1 was lower for HDR. The impotence rate was decrease by half with HDR. Neoadjuvant hormonal therapy and 14 or greater needles were significantly associated with increased chronic urinary toxicity on multivariate analysis.
