Abstract

Objective: To compare the clinicopathologic findings of African-American (AA) and White-American (WA) men with prostate cancer (PCa) who were candidates for active surveillance (AS) and underwent radical prostatectomy (RP). Methods: Prospectively maintained database of men who underwent RP from 2 academic centers were analyzed retrospectively. Postoperative pathologic characteristics of patients who met the AS inclusion criteria of the University of California, San Francisco (UCSF) and National Comprehensive Cancer Network (NCCN) were evaluated. After RP, the rate of pathological upstaging and Gleason upgrading were compared between AA and WA men. Results: In the AA cohort, 196 and 124 men met the UCSF and NCCN criteria for AS, respectively. With respect to WA patients, 191 and 148 fulfilled the AS criteria for UCSF and NCCN, respectively. AA men had a higher percentage of maximum biopsy core than WA men (15.3%-20.4% vs 11.5%-15.0%, P <.05, respectively) in both cohorts. In addition, a greater proportion of AA men had multiple positive biopsy cores compared to WA men (45.2% vs 33.1%, P =.046) under the NCCN criteria. A higher proportion of AA men were upstaged (≥pT3) compared to WA men (19.4% vs 10.1%, P =.037). A multivariate regression test revealed that age, preoperative PSA, and number of positive cores were independent predictors of more advanced disease (upstaging and/or upgrading) in AA men. Conclusion: AA men who were candidates for AS criteria had worse clinicopathological features on final surgical pathology than WA men. These results suggest that a more stringent AS criteria should be considered in AA men with prostate cancer.
