ence of prostate cancer 25 years after this irradiation program.  To compare like populations, this study compares patients treated between 1984-2000 to two previous studies that looked at patients who had surgical radical prostatectomy. The 15 years of follow-up data for these three studies calculated disease-free survival (DFS) based on a PSA<0.2 ng/dl. The surgical definition is much stricter than the one usually used in radiation therapy studies.  Results of these three studies showed comparable DFS at 10 (75 percent, 77 percent and 77 percent) and 15 years of follow-up (73 percent, 68 percent and 75 percent) respectively, showing that prostatectomy and the combination of seed implant followed by external beam radiation therapy are equally effective.  A sub analysis of patients treated with transperineal implants and external beam radiation therapy between 1995 and 2000 in our study showed a 15-year disease-free survival of 79 percent.

A secondary analysis in this publication includes over 300 men treated 16-25 years ago whose prostate cancer recurred after treatment.  Recurrences were PSA defined and results showed the majority of recurrences happened within the first five years after treatment and no recurrences 15.5-25 years after treatment.  This is the first to include interval censoring analysis when looking at time to recurrence. 

This study concludes that follow-ups are necessary for 15 years after treatment to fully evaluate any treatment for prostate cancer. If a man's PSA is <0.20 ng/ml 15 years post treatment, later recurrence of the disease should be rare. For more information, visit www.curingprostatecancer.com.
