Introduction:
Very low-risk prostate cancer (PCa) is being increasingly managed by active surveillance (AS). Our aim was to assess the influence of the origin of diagnosis on PCa characteristics and treatment rates among men with very low-risk PCa in our prospective AS cohort.
Methods:
Overall, 191 men with very low-risk PCa fulfilling Epstein-criteria underwent protocol-based AS. These men originated either from the prospective population-based screening program (P-AS) or were diagnosed by opportunistic screening (O-AS).
Results:
Overall, n = 86 (45.0%) originated from the P-AS group, whereas n = 105 (55.0%) from the O-AS group. On univariate Cox regression analysis, age (HR 0.96, 95% CI 0.92-1.00; p = 0.05), origin of diagnosis (HR 0.72, 95% CI 0.41-1.28; p = 0.001), number of positive cores (HR 2.15, 95% CI 1.18-3.90; p = 0.01) and maximum core involvement (HR 1.03, 95% CI 0.99-1.05; p = 0.05) were predictors for treatment necessity. On multivariate analysis, age (HR 0.95, 95% CI 0.89-0.99; p = 0.05), number of positive cores (HR 2.07, 95% CI 1.10-3.88; p = 0.02), maximum core involvement (HR 1.03, 95% CI 1.00-1.06; p = 0.04) but not origin of diagnosis were independent predictors for treatment necessity. Four men developed biochemical recurrence (all from O-AS group [p = 0.05]).
Conclusion:
The origin of PCa diagnosis in men undergoing AS had no influence on disease progression and treatment necessity.
