Outcomes of Men with Screen-Detected Prostate Cancer Eligible for Active Surveillance Who Were Managed Expectantly

Abstract Background The incidence of small, localised, well-differentiated prostate cancer (PCa) is increasing, mainly as a result of screening. Many of these cancers will not progress, and radical therapy may lead to substantial overtreatment. Active surveillance (AS) has emerged as an alternative. Objective To retrospectively validate the currently used criteria for eligibility for AS. Design, setting, and participants For this cohort study, data from 616 men who were diagnosed with PCa between 1994 and 2007 at a mean age of 66.3 yr in four centres of the European Randomized Study of Screening for Prostate Cancer (ERSPC) were combined. All patients fit the criteria for AS (prostate-specific antigen [PSA] ≤10.0 ng/ml, PSA-density
