clinicaloptions.com/hiv Non-AIDS–Defining Cancers in Post-HAART Era Background  HIV-infected patient survival rate significantly improved by HAART –Decreased incidence of AIDS-defining infections and cancer –Longer patient survival linked with increase in several chronic conditions, eg, lipodystrophy, metabolic syndrome, osteopenia, cardiovascular disease, non-AIDS– defining cancers  Studies of non-AIDS–defining cancers in HIV-infected patients –Limited by population size and demographics –Lack of comparison to uninfected control patients –Fail to include patients at all HIV infection stages –Do not focus on trends in cancer incidence since advent of HAART  Present study compared cancer incidence rates from 2 large, prospective cohort studies of HIV-infected patients with those in the general population –Included all stages of HIV infection Patel P, et al.

clinicaloptions.com/hiv Non-AIDS–Defining Cancers in Post-HAART Era Summary of Study Design  Cancer incidence estimated from combination of ASD [1] and HOPS [2] databases –Data not statistically different between studies, combined to better represented HIV- infected population than either study alone  Cancer incidence in HIV-infected cohorts compared with that in general population (derived from the [SEER program [3] )  Incidence rates determined for 3 observation periods [4] –Pre-HAART ( ) –Early HAART ( ) –Recent HAART ( )  Incidence rates reported as per 100,000 person-years 1.

clinicaloptions.com/hiv Non-AIDS–Defining Cancers in Post-HAART Era Main Findings (cont’d)  Cancer incidence rates in general population over 3 observation periods –Decreased significantly for Kaposi’s sarcoma, non-Hodgkin’s lymphoma, and cervical, lung, and oropharyngeal cancers –Increased significantly for anal, colorectal, liver, and prostate cancers  Relative incidence of Kaposi’s sarcoma, non-Hodgkin’s lymphoma significantly decreased over time in HIV-infected population vs general population, whereas relative incidence of anal cancer increased significantly Patel P, et al.
