Followup prostate biopsy in patients with carcinoma of the prostate treated by 192iridium template irradiation plus supplemental external beam radiation.

We reviewed our experience with 81 patients who had undergone followup needle biopsies of the prostate between 12 and 27 months after 192iridium template radiotherapy combined with external beam radiation therapy. When broken down by stage 82% of the patients with stage A2, 92% with B1, 95% with B2 and 55% with C disease demonstrated a negative biopsy and adequate local control of the cancer. We believe that in elderly patients, poor risk patients with early stage disease and stage C lesions this low morbidity, low mortality therapy offers a viable option to other modalities of treatment.
