Three-year Active Surveillance Outcomes in a Contemporary Community Urology Cohort in the United States.

To determine the 3-year outcomes of men with prostate cancer managed with active surveillance (AS) in a cohort of geographically diverse community-based urology practices. AS is the management of choice for a majority of men with lower risk prostate cancer. Five hundred and forty-eight men on AS were followed for a median of 3.35 years. 89% (492) continued to follow-up with diagnosing practice. 32% (171) discontinued AS. On multivariate analysis, increasing NCCN risk classification (Hazard ratio [HR] 1.65, P = 0.02 and HR 2.09, P < 0.01 for low and intermediate risk vs very low risk) was significantly associated with discontinuation. Among those who discontinued AS, surgery and radiation were utilized equally (47% and 53%, respectively, P = 0.48). In this community-based cohort of men on AS, a minority was lost to follow-up and adherence to AS was similar to other reports. Disease characteristics more than sociodemographic characteristics correlated with adherence to AS, while surgery and radiotherapy were utilized equally among those discontinuing AS, both suggesting guideline concordant practice of medicine.
