Permanent Prostate Brachytherapy Using CS-131 for Localized Prostatic Carcinoma: A Phase II Study

(Recruitment Complete)

The purpose of this study is to scientifically evaluate the effects (good and bad) of a new type of radioactive treatment in patients with prostate cancer.  The effects of placing a new type of small radioactive pellets (hereinafter called seeds) inside your prostate (brachytherapy), called Cesium–131 (Cs-131).

This research is being done to see what advantages, if any, Cs-131 may have over the other commonly used seeds, such as Iodine (I-125) and Palladium (Pd-103).

About 100 men in the United States will take part in this initial study.

You will be enrolled onto the study after your consent to do so and once you are determined by your doctor to be a candidate.  This is a single arm type trial, meaning that there is no “experimental treatment” being compared.  Cs-131 is very similar to the other commonly used isotopes, but has a shorter duration of effect on the tissue.  It was approved for use in human patients by the FDA in 2004.
