title: Percutaneous iodine-125 seed implantation for carcinoma of the prostate.
abstract: This study was performed to assess the early results of treating stages T1-T3 adenocarcinoma prostate with either Iodine-125 (125I) implant alone (Group 1), for smaller more well differentiated cancers, or with low dose external beam radiation followed by a 125I boost (XRT + 125I) (Group 2) for larger less well differentiated tumours. Eighty-six patients were followed for between 11 and 60 months with a mean follow up of 26.1. All patients were followed by regular prostate specific antigen (PSA) evaluations, and digital rectal examinations (DRE). Eighty patients had a follow-up biopsy at 1 year. Prostate specific antigen progression-free survival (PSA-PFS) was determined and defined. Complications and potency were also assessed. Early results of 125I prostate seed implantation are very promising especially for selected cases of localized carcinoma.
