Abstract

BACKGROUND.: Non-AIDS defining cancers (non-ADCs) have become the leading non-AIDS-related cause of death among people with HIV/AIDS. We aimed to quantify the excess risk of cancer-related deaths among Italian people with AIDS (PWA), as compared to people without AIDS (non-PWA). METHODS.: A nationwide, population-based, retrospective cohort study was carried out among 5285 Italian PWA, aged 15-74 years, diagnosed between 2006 and 2011. Date of death and multiple-cause-of-death (MCoD) data were retrieved up to December 2011. Excess mortality, as compared to non-PWA, was estimated using sex- and age-standardized mortality ratios (SMRs) and corresponding 95% confidence intervals (CIs). RESULTS.: Among 1229 deceased PWA, 10.3% reported non-ADCs in the death certificate, including lung (3.1%) and liver (1.4%) cancers. A 7.3-fold (95% CI: 6.1-8.7) excess mortality was observed for all non-ADCs combined. Statistically significant SMRs emerged for specific non-ADCs, i.e., anus (5 deaths, SMR=227.6, 95% CI: 73.9-531.0), Hodgkin lymphoma (12 deaths, SMR=122.0, 95% CI: 63.0-213.0), unspecified uterus (4 deaths, SMR=52.5, 95% CI: 14.3-135.0, liver (17 deaths, SMR=13.2, 95% CI: 7.7-21.1), skin melanoma (4 deaths, SMR=10.9, 95% CI: 3.0-27.8), lung (38 deaths, SMR=8.0, 95% CI: 5.7-11.0), head and neck (9 deaths, SMR=7.8, 95% CI: 3.6-14.9), leukemia (5 deaths, SMR=7.6, 95% CI: 2.4-17.7), and colon-rectum (10 deaths, SMR=5.4, 95% CI: 2.6-10.0). SMRs for non-ADCs were particularly elevated among PWA infected through injecting drug use. CONCLUSION.: This population-based study documented extremely elevated risks of death for non-ADCs among PWA. These findings stress the need of preventive interventions for both virus-related and non virus-related cancers among HIV-infected individuals.
