Editing Biochemical Recurrence (section)

=== Epidemiology ===

* '''Incidence: ≈25-41% develop PSA recurrence within 10 years of radical prostatectomy'''
** '''In patients that have BCR after radical prostatectomy'''
*** ≈50% of recurrences appear within 3 years
*** ≈80% within 5 years
*** '''≈99% within 10 years'''
*** Rarely, BCR can occur > 15 years after radical prostatectomy
*** '''Clinical implication: given low risk of recurrence after 10 years and protracted course of untreated biochemical recurrence (see Pound et al. below), likely low utility of PSA follow-up beyond 10 years, particularly in older patient (average life expectancy of US male in 2018: 78.5)'''
