Testing radioactive seeds implanted directly into recurring prostate tumors

This trial is testing a new treatment called DaRT (Diffusing Alpha Emitters Radiation Therapy) seeds for men whose prostate cancer has come back in the same area after previous treatment. The treatment involves placing tiny radioactive seeds directly into the tumor to kill cancer cells. Researchers want to see if this approach is safe and works well for patients with locally recurrent prostate cancer.

Men whose prostate cancer returns in the same location after initial treatment have limited options. This trial exists to see whether implanting radioactive seeds directly into the tumor could be a effective new way to treat these recurrent cancers while potentially causing fewer side effects than other radiation approaches.
