To evaluate the impact of body mass index (BMI) on the 8-year biochemical outcome after permanent prostate brachytherapy with or without the addition of supplemental external beam radiotherapy and/or androgen deprivation therapy (ADT). ⋯ Prostate brachytherapy results in a high probability of 8-year biochemical progression-free survival for low, intermediate, and high-risk patients. When integrated across risk groups and hormonal status, BMI had no statistically significant influence on biochemical progression-free survival.
