Answer

Generally, after a radical prostatectomy, the PSA level should be less than 0.2 ng/mL and, after radiation therapy, the level should be less than 0.5 ng/mL. [23] The definition of a rising PSA level is not consistent in the literature, but many agree that the occurrence of 2 consecutive PSA level elevations is considered biochemical failure. Other important prognostic indicators include the PSA velocity, time to PSA nadir, time to PSA recurrence, and pattern of PSA recurrence.

Pretreatment Gleason score, clinical stage, PSA level, and percentage of positive core biopsy results have been found to be reliable predictors of failure following local therapy. Unfortunately, no means of identifying recurrences limited to the pelvis is reliable. Although a Gleason grade of 7 or less is associated with a better prognosis than a grade of 8 or more, if the PSA level rise occurs after 2 years following local treatment, the associated survival likelihood is greater than if the rise occurs before 2 years.
