Improved survival for patients with prostate cancer receiving high-dose-rate brachytherapy boost to EBRT compared with EBRT alone

High-dose-rate (HDR) brachytherapy boost is a treatment of intermediate- to high-risk prostate cancer, but long-term clinical outcome data are sparse. We report long-term survival and toxicity data in a cohort of patients treated in a single institution.Between 1998 and 2004, 654 patients with localized prostate cancer received either 3-dimensional conformal radiotherapy (median 46 Gy) with an HDR (median 18 Gy in three fractions) boost ("3-D...
