Background: Experiences of African/Afro-Caribbean men on active surveillance (AS) for prostate cancer (PCa) in the United Kingdom (UK) are not well documented. We compared follow-up appointments, adherence, and clinical outcomes among African/Afro-Caribbean men on AS at a high-volume UK hospital with other ethnicities. Methods: Men with confirmed low-intermediate risk Pca who attended the AS clinic (2005–2016) and had undergone ≥1 follow-up biopsy (n = 458) were included. Non-adherence (defined as >20% missed appointments), suspicion of disease progression (any upgrading, >30% positive cores, cT-stage > 3, PIRADS > 3), any upgrading from diagnostic biopsy and conversion to active treatment (prostatectomy, radiotherapy or hormone therapy) according to ethnicity (African/Afro-Caribbean versus other ethnicities) were assessed using multivariable regression analysis. Results: Twenty-three percent of eligible men were recorded as African/Afro-Caribbean, while the remainder were predominantly Caucasian. African/Afro-Caribbean men had slightly lower PSA at diagnosis (median 5.0 vs. 6.0 ng/mL) and more positive cores at diagnosis (median 2 vs. 1). They had a substantially higher rate of non-attendance at scheduled follow-up visits (24% vs. 10%, p < 0.001). Adjusted analyses suggest African/Afro-Caribbean men may be at increased risk of disease progression (hazard ratio [HR]: 1.38; 95% confidence interval [CI] 0.99–1.91, P = 0.054) and upgrading (HR: 1.29; 95% CI 0.87–1.92, P = 0.305), though neither reached statistical significance. No difference in risk of conversion to treatment was observed between ethnic groups (HR: 1.03; 95% CI 0.64–1.47, P = 0.873). Conclusions: African/Afro-Caribbean men on AS for PCa in the UK are less likely to adhere to scheduled appointments, suggesting a more tailored service addressing their specific needs may be required. While African/Afro-Caribbean men were no more likely to convert to treatment than Caucasian/other men, findings of a potentially higher risk of disease progression signal the need for careful selection and monitoring of African/Afro-Caribbean men on AS. Larger prospective, multicentre studies with longer follow-up are required to provide more definitive conclusions. Refereed/Peer-reviewed
