Are HIV-infected men vulnerable to prostate cancer treatment disparities? - Abstract

Background: HIV-infected (HIV+) men face cancer treatment disparities which impact outcome.

Prostate cancer (PCa) treatment and treatment appropriateness in HIV+ men are unknown.

Methods: We used electronic chart review to conduct a retrospective cohort study of 43 HIV+ cases with PCa and 86 age- and race-matched HIV-uninfected (HIV-) controls with PCa, aged 40-79, from 2001-2012. We defined treatment appropriateness using National Comprehensive Cancer Network (NCCN) guidelines and the Charlson Co-morbidity Index (CCI) to estimate life expectancy.

Results: Median age was 59.5 years at PCa diagnosis. Median CD4+ T-cell count was 459.5cells/mm3, 95.3% received antiretroviral therapy, and 87.1% were virally suppressed. Radical prostatectomy (RP) was the primary treatment for 39.5% of HIV+ and 71.0% of HIV- men (p= 0.004). Only 16.3% of HIV+ vs. 57.0% of HIV- men received open RP (p< 0.001). HIV+ men received more radiotherapy (25.6% vs. 16.3%, p= 0.13). HIV was negatively associated with open RP (OR= 0.03, p= 0.007), adjusting for insurance and CCI. No men were undertreated. Fewer HIV+ men received appropriate treatment (89.2% vs. 100%, p= 0.003), due to 4 overtreated HIV+ men. Excluding AIDS from the CCI still resulted in fewer HIV+ men receiving appropriate treatment (94.6% vs. 100%, p = 0.03).

Conclusion: PCa in HIV+ men is largely appropriately treated. Under-or overtreatment may occur from difficulties in life expectancy estimation. HIV+ men may receive more radiotherapy and fewer RPs, specifically open RPs.

Impact: Research on HIV/AIDS survival indices and etiologies and outcomes of this PCa treatment disparity in HIV+ men is needed.
