Abstract
BACKGROUND: It is unclear whether cancer risk among people with human immunodeficiency virus (HIV, PWH) has declined equally across all racial/ethnic and transmission risk groups. METHODS: We used data on PWH aged ≥20 years from the HIV/AIDS Cancer Match Study during 2001-2019. We used Poisson regression to assess time trends in incidence rates for each cancer site by racial/ethnicity and risk groups, adjusting for age, registry, and sex. We also estimated adjusted rate ratios across racial and ethnic and risk groups in 2001-2004 and 2015-2019. RESULTS: Trends in age-standardized rates differed across racial/ethnic groups and across risk groups for some cancers. For example, liver cancer rates declined 23% per 5-year period among White PWH, 11% among Black PWH, and 18% among Hispanic PWH. Anal cancer rates declined among men who have sex with men, were stable among people who inject drugs, and increased among other risk groups. Between 2001-2004 and 2015-2019, the relative difference in cancer incidence rates by race/ethnicity increased for Hodgkin lymphoma (HL) and liver cancer but decreased for non-Hodgkin lymphoma (NHL); by risk group, relative differences increased for NHL and liver cancer and decreased for HL and lung and anal cancers. CONCLUSIONS: Among PWH in the United States during 2001-2019, HL, lung, liver, and cervical cancer rate trends were different across racial/ethnic groups. HL, lung, anal, and liver cancer rate trends were different across risk groups. Future work should examine underlying causes of the differences in trends.
