Based on recent, important publications on the impact of brachytherapy in the management of prostate cancer, we analysed already validated indications and the "under investigations" use of brachytherapy. Published studies (MEDLINE), randomized trials and recommendations were reviewed, as well as Delphi consensus when available. While low-dose rate brachytherapy remains a standard of care for low-risk eligible patients, three randomized trials are now available to consider that combination of external beam radiation therapy with brachytherapy boost (low- or high-dose rate) appears as a recommended treatment for intermediate and high-risk patients. Other indications of prostate brachytherapy (monotherapy and salvage) remain under evaluation. For low-risk patients with good urinary status, low-dose rate brachytherapy alone should be offered. For low-intermediate risk prostate cancer, low-dose rate brachytherapy alone may be offered as monotherapy, while for high-intermediate risk prostate cancer, a combination of external beam radiation therapy (with or without androgen deprivation therapy) plus brachytherapy boost (low- or high-dose rate) should be offered to eligible patients. For patients with high-risk prostate cancer receiving external beam radiation therapy and androgen deprivation therapy, brachytherapy boost (low- or high-dose rate) should be offered to eligible patients. High-dose rate brachytherapy as monotherapy (single dose for low-risk/multifractionated for intermediate and high-risk) must be explored under clinical investigations, as well as salvage brachytherapy for local recurrence.
