Dose escalation has been shown to improve biochemical outcome in localised prostate cancer. An HDR brachytherapy boost is an effective strategy for dose escalation, since it exploits the low α/β ratio in prostate cancer, allowing the delivery of a high biological dose to the tumour. We sought to evaluate the biochemical disease free survival in patients with intermediate and high risk localised prostate cancer treated with EBRT plus HDR brachytherapy as a boost, in our institution. ⋯ These data confirm that EBRT plus a single-fraction HDR brachytherapy boost achieves good biochemical control in a cohort of predominantly high risk patients.
