title: Risk of cancer in patients with HIV disease. London African HIV/AIDS Study Group.
abstract: The aim of this study was to compare cancer incidence in a cohort of HIV-infected patients with the incidence rates in the population of South East England. Data collected for a retrospective cohort study of 2048 HIV-infected patients were analysed to examine the incidence of cancer. Cases of cancer occurring in South East England from 1985-1995 were obtained from the Thames Cancer Registry. Standardized incidence ratios were calculated by comparison of the observed number of cases for each cancer type in HIV-infected non-Africans with the numbers expected, calculated from the age and sex specific registration rates for the South East England population using person-years of observation. The crude incidence rates of cancer were calculated for HIV-infected Africans. The incidence of non-AIDS defining cancers such as Hodgkin's disease (standardized incidence ratio 22; 95% CI: 3-80) and anal cancer (standardized incidence ratio 125; 95% CI: 3-697) were significantly increased for non-African males with HIV disease. Anal cancer was also significantly increased for non-African females (standardized incidence ratio 1667; 95% CI: 43-9287). Kaposi's sarcoma (KS) was the commonest cancer among HIV-infected Africans and males had an incidence which was nearly 3 times that of females. There is evidence to suggest that the risks for other non-AIDS defining cancers were significantly increased in persons with HIV disease which may have implications for HIV/AIDS surveillance.
