What is the success rate of brachytherapy?
The results of prostate brachytherapy are comparable to those of radical prostatectomy for five to seven years after treatment. The long-term data (longer than 10 years after treatment) are limited. Studies demonstrate success rates of 74% at seven years, with success being defined by either a PSA of less than 0.5 ng/mL or the absence of three consecutive rises in PSA in patients who received brachytherapy and external beam radiation therapy (EBRT).
