Looks like 4 years of <0.2 PSA post-treatment gets you a "biochemical cure". (= disease-free beyond 10 years.)
Study Highlights
• Close to 80% of men 4–5 years after LDR prostate brachytherapy will achieve a PSA of 0.2 ng/ml or less.
• PSA ≤ 0.2 ng/ml is associated with 97–99% freedom from prostate cancer recurrence at 10–15 years.
• This applies across all risk groups and to LDR brachytherapy alone or combined with ADT and/or EBRT.
