Radioactive seed implantation

Radioactive seeds are tiny pieces of radioactive material that are placed in your prostate gland (a procedure known as implantation or "brachytherapy") and release high doses of radiation in the prostate. The seeds are permanent, emitting decreasing amounts of radiation for about one year, until the seeds are no longer radioactive. Because the radiation dose is localized to the prostate, side effects to other organs are minimized.

Radioactive seed implantation can be performed either alone or in conjunction with other treatments. This decision will be based on a review of your prognostic factors, which help predict the risk of the cancer spreading beyond the prostate. Accompanying treatments include:

  • External beam radiation therapy
    If you and your radiation oncologist decide that both implantation and radiation therapy are necessary, external beam radiation therapy will be completed first. Treatment lasts five weeks. The radioactive seed implantation will take place about three to four weeks after the radiation therapy has ended.
  • Hormone therapy
    Depending on the size of the prostate and prognostic factors, you may need to be placed on a hormone therapy regimen after the implantation. Your radiation oncologist will discuss this option with you.
If you decide to undergo radioactive seed implantation, you will first undergo a volume study, followed by either implantation or external beam radiation therapy.
