Abstract

Background: Consensus guidelines recommend that active surveillance (AS) be considered in the management of men with low risk prostate cancer (LRPC). The evidence supporting this recommendation is largely derived from studies in which men of African descent were underrepresented; thus, the appropriate implementation of AS in this population remains controversial. The objective of our study was to evaluate the prevalence and clinical predictors of an AS approach in black men (BM) diagnosed with LRPC following the 2010 inclusion of AS in LRPC management consensus guidelines. Methods: BM (N = 15,242) and non-Hispanic white men (WM) (N = 86,655) diagnosed with LRPC (as defined by PSA ≤ 10 ng/ml, Gleason score ≤ 6, clinical stage T1 – T2a) between 2010 and 2013 were identified from the National Cancer Database. Logistic regression models were used to assess the likelihood of pursuing an AS strategy over time, as well as to examine associations between sociodemographic characteristics (SDCs) and the receipt of AS. Results: Overall, 9% of BM with LRPC were managed with AS. On univariate analysis, the likelihood of BM undergoing AS increased from 2010 and was statistically significant ( p < 0.001) for all subsequent years (2011: OR = 1.54, 95% CI 1.30-1.82; 2012: OR = 2.19, 95% CI 1.82-2.60; 2013: OR = 2.55, 95% CI 2.15-3.02). Uninsured BM were twice as likely as those with private insurance to pursue AS (OR 1.97, 95% CI 1.51-2.58, p < 0.001). BM seen at academic cancer programs were also more likely to be managed with AS, when compared to those seen at community cancer centers (OR 1.47, 95% CI 1.37-1.60, p < 0.001). BM were less likely than WM to receive AS (OR = 0.82, 95% CI 0.77 to 0.87, p < 0.001). On multivariate analysis adjusted for SDCs, there was no significant difference in AS utilization between the two ethnic groups. Conclusions: The utilization of AS for BM with LRPC appears to be increasing, may be influenced by SDCs, and may not differ from the AS utilization for WM with LRPC. Given the observed elevated rates of post-prostatectomy adverse pathologic features among BM, further evaluation of the determinants of AS utilization and scrutinous consideration of the appropriateness of AS in this population is warranted.
