Brachytherapy



Brachytherapy Seeds

Prostate brachytherapy is known in layman terms as a radioactive seed implant. It involves permanently implanting tiny radioactive seeds into the prostate with a needle and these seeds gradually lose their therapeutic radioactivity over 6 months. This form of localized prostate cancer allows us to deliver 3 times more radiation to the prostate as compared to external beam radiation with less radiation exposure to the bladder and rectum. It is a 1-2 hour out-patient procedure performed by a special surgical medical team consisting of a radiation oncologist, urologist and a physicist. Our technique uses state-of-the-art equipment allowing real-time 3 dimensional computerized imaging of the prostate and it takes into account the radioactivity of each individual seed as it is placed. Depending on the size of the prostate the number of implanted seeds can range between 40 and 80 or more. Most patients go home from the hospital the same day and many do not need a catheter and are able to return to work in 3-5 days. Limitations to brachytherapy include excessively large prostate size or significant urinary symptoms which may preclude us from offering this procedure to certain patients. Prostate seed implantation has understandably become a popular treatment option particularly in men above the age of 65.
