When it’s safe to stop PSA monitoring

Japanese researchers have determined when it’s safe to stop PSA monitoring after radical prostatectomy.

Their work, published in the Journal of Urology, suggests that if the PSA level, measured by an ultrasensitive assay, remains undetectable 3-5 years after radical prostatectomy, PSA monitoring could reasonably be stopped.

By then, the probability of biochemical recurrence is extremely low, they say.

For this 10-year study, nearly 600 patients who underwent prostatectomy were followed and then stratified according to PSA at three and five years after
