Biochemical outcome of prostate cancer patients treated with hypofractionated external radiation and a single high-dose-rate brachytherapy boost.

Introduction: Treating localized high-risk prostate cancer with a combination of external beam radiation therapy (EBRT) and high-dose-rate brachytherapy (HDR-BT) is a common approach. Moderately hypofractionated EBRT and a single HDR-BT boost simplifies the treatment. We aim to present our five-year results.
