Salvage brachytherapy for recurrent prostate cancer after definitive radiation therapy: A comparison of low-dose-rate and high-dose-rate brachytherapy and the importance of prostate-specific antigen doubling time

Background Salvage brachytherapy is a treatment option for patients with locally recurrent prostate cancer after primary radiation therapy. We reviewed our experience using low-dose-rate (LDR) or high-dose-rate (HDR) brachytherapy to compare the outcome and toxicity profiles of each approach in the salvage brachytherapy setting. Methods and Materials Ninety-eight patients with biopsy-proven locally recurrent prostate cancer who underwent salvage...
