Modern brachytherapy for treatment of prostate cancer

Abstract

Background: Prostate cancer is the most common cancer diagnosed in men. An increasing number of these patients are seeking minimally invasive procedures such as transperineal interstitial permanent radioactive seed prostate brachytherapy.

Methods: This paper reviews the historical perspective and the current advances in transperineal interstitial permanent radioactive seed prostate brachytherapy. The 10- to 15-year results data now published for brachytherapy alone or in combination with external-beam irradiation are also reviewed.

Results: Modern brachytherapy using transperineal interstitial permanent radioactive seed prostate brachytherapy offers patients an excellent quality of life with convenient outpatient treatment with long-term (10- to 15-year) biochemical relapse-free survival rates ranging from 67% to 87%, depending on risk stratification.

Conclusions: Modern-day brachytherapy utilizing either radioactive iodine-125 or palladium-103 alone or in combination with supplemental external-beam treatment offers patients a successful treatment outcome with acceptable toxicity.
