Transperineal radioactive seed implantation is a radiation therapy modality available at the Indiana University School of Medicine for treatment of localized prostate cancer. This program is jointly administered by the Departments of Urology and Radiation Oncology as part of the integrated genitourinary oncology program. Between 70 and 150 radioactive seeds (approximately the size of a grain of rice) are implanted in the prostate for treatment. This allows higher doses of radiation to be delivered to the tumor site while limiting risk of damage to surrounding normal tissues and structures. An ultrasound is performed approximately one week before the procedure. From this ultrasound, the radiation oncologist maps the prostate (also referred to as a volume study). This volume study assists the radiation oncologist in determining the quantity and distribution of seeds needed to treat the prostate. The procedure is performed under spinal anesthesia and with ultrasound guidance on an outpatient basis. The patient is usually able to return to normal activity within forty-eight hours.
