Five-year treatment failure-free survival, metastasis-free survival, cancer specific survival and overall survival were 100%.
Percent of PSA decreased at nadir = (PSA at entry – PSA nadir)/(PSA at entry × 100).
Radical treatment defined as any whole gland treatment.
Treatment failure defined as any whole gland treatment, ADT initiation, metastasis and PCa specific mortality.
