N2 - Purpose To assess long-term outcomes of men with favorable-risk prostate cancer in a prospective, active surveillance program. Methods Curative intervention was recommended for disease reclassification to higher cancer grade or volume on prostate biopsy. Primary outcomes were overall, cancer-specific, and metastasis-free survival. Secondary outcomes were the cumulative incidence of reclassification and curative intervention. Factors associated with grade reclassification and curative intervention were evaluated in a Cox proportional hazards model. Results A total of 1,298 men (median age = 66 y) with a median follow-up of 5 years (range: 0.01–18.00 y) contributed 6,766 person-years of follow-up since 1995. Overall, cancer-specific, and metastasis-free survival rates were 93%, 99.9%, and 99.4%, respectively, at 10 years and 69%, 99.9%, and 99.4%, respectively, at 15 years. The cumulative incidence of grade reclassification was 26% at 10 years and was 31% at 15 years; cumulative incidence of curative intervention was 50% at 10 years and was 57% at 15 years. The median treatment-free survival was 8.5 years (range: 0.01–18 y). Factors associated with grade reclassification were older age (hazard ratio [HR] = 1.03 for each additional year; 95% CI: 1.01–1.06), prostate-specific antigen density (HR = 1.21 per 0.1 unit increase; 95% CI: 1.12–1.46), and greater number of positive biopsy cores (HR = 1.47 for each additional positive core; 95% CI: 1.26–1.69). Factors associated with intervention were prostate-specific antigen density (HR = 1.38 per 0.1 unit increase; 95% CI: 1.22–1.56) and a greater number of positive biopsy cores (HR = 1.35 for one additional positive core; 95% CI: 1.19–1.53). Conclusion Men with favorable-risk prostate cancer should be informed of the low likelihood of harm from their diagnosis and should be encouraged to consider surveillance rather than curative intervention.
