Five-Year Prospective Observational Study of African-American Men on Active Surveillance for Prostate Cancer Demonstrates Race Is Not Predictive of Oncologic Outcomes.

This study aimed to evaluate if race impacted outcomes or risk of disease progression in men on active surveillance (AS) for prostate cancer. We present the results from our majority African-American cohort of men in an equal access setting over a 5-year follow-up period.

All patients who elected AS for prostate cancer at the Southeast Louisiana Veterans Health Care System are entered into a prospectively managed observational database. Patients were divided into groups based on self-reported race. Grade group progression was defined as pathologic upgrading above International Society of Urological Pathology Grade Group 1 disease on subsequent biopsies following diagnostic biopsy. All tests were 2 sided using a significance of .05.

A total of 228 men met inclusion criteria in the study, including 154 non-Hispanic African American and 74 non-Hispanic Caucasian American men, with a median follow-up of 5 years from the initiation of AS. Race was not predictive of Gleason grade progression, AS discontinuation, or biochemical recurrence on Cox multivariate analysis (HR = 1.01, 0.94, 0.85, P = .96, .79, .81, respectively). On Kaplan-Meier analysis at 5 years, African-American progression-free, AS discontinuation free, and overall survival probability was comparable to their Caucasian American counterparts (P > .05 for all).

Active surveillance is a safe treatment option for low and very low risk prostate cancer, regardless of race. African-American and Caucasian-American men did not have any significant difference in Gleason grade group progression in our cohort with 5-year follow-up.
