Brachytherapy for Prostate Cancer 2017

In the Toronto study of 776 patients, all patients with a PSA rising beyond 30 months were investigated by prostate biopsy examination, and, if the biopsy was negative, systemic staging was initiated as PSA approached 10 ng/ml and there were:

- 8 local failures (1.0%) - 8 distant failures (1.0%) - 9 failures of unknown site (1.2%)

Thus, the local relapse rate should range from 1.0% to 2.2% , but it is likely to be closer to the biopsy-proven 1.0% of patients, because all other men with biochemical failure in this cohort had negative biopsy results
