          Abstract

          Cancers associated with immunosuppression and infections have long been recognized as a major complication of HIV/AIDS. More recently, persons living with HIV are increasingly diagnosed with a wider spectrum of HIV-associated malignancies (HIVAM) as they live longer on combination antiretroviral therapy. This has spurred research to characterize the epidemiology and determine the optimal management of HIVAM with a focus on low-and middle-income countries (LMICs). Given background coinfections, environmental exposures, host genetic profiles, antiretroviral therapy usage, and varying capacities for early diagnosis and treatment, one can expect the biology of cancers in HIV-infected persons in LMICs to have a significant impact on chronic HIV care, as is now the case in high-income countries. Thus, new strategies must be developed to effectively prevent, diagnose, and treat HIVAM in LMICs; provide physical/clinical infrastructures; train the cancer and HIV workforce; and expand research capacity-particularly given the challenges posed by the limitations on available transportation and financial resources and the population's general rural concentration. Opportunities exist to extend resources supported by the President's Emergency Plan for AIDS Relief and the Global Fund to Fight AIDS, Tuberculosis, and Malaria to improve the health-care infrastructure and train the personnel required to prevent and manage cancers in persons living with HIV. These HIV chronic care infrastructures could also serve cancer patients regardless of their HIV status, facilitating long-term care and treatment for persons who do not live near cancer centers, so that they receive the same degree of care as those receiving chronic HIV care today.

            Cancer burden in the HIV-infected population in the United States.

            Effective antiretroviral therapy has reduced the risk of AIDS and dramatically prolonged the survival of HIV-infected people in the United States. Consequently, an increasing number of HIV-infected people are at risk of non-AIDS-defining cancers that typically occur at older ages. We estimated the annual number of cancers in the HIV-infected population, both with and without AIDS, in the United States. Incidence rates for individual cancer types were obtained from the HIV/AIDS Cancer Match Study by linking 15 HIV and cancer registries in the United States. Estimated counts of the US HIV-infected and AIDS populations were obtained from Centers for Disease Control and Prevention surveillance data. We obtained estimated counts of AIDS-defining (ie, Kaposi sarcoma, non-Hodgkin lymphoma, and cervical cancer) and non-AIDS-defining cancers in the US AIDS population during 1991-2005 by multiplying cancer incidence rates and AIDS population counts, stratified by year, age, sex, race and ethnicity, transmission category, and AIDS-relative time. We tested trends in counts and standardized incidence rates using linear regression models. We multiplied overall cancer rates and HIV-only (HIV infected, without AIDS) population counts, available from 34 US states during 2004-2007, to estimate cancers in the HIV-only population. All statistical tests were two-sided. The US AIDS population expanded fourfold from 1991 to 2005 (96,179 to 413,080) largely because of an increase in the number of people aged 40 years or older. During 1991-2005, an estimated 79 656 cancers occurred in the AIDS population. From 1991-1995 to 2001-2005, the estimated number of AIDS-defining cancers decreased by greater than threefold (34,587 to 10,325 cancers; P(trend) < .001), whereas non-AIDS-defining cancers increased by approximately threefold (3193 to 10,059 cancers; P(trend) < .001). From 1991-1995 to 2001-2005, estimated counts increased for anal (206 to 1564 cancers), liver (116 to 583 cancers), prostate (87 to 759 cancers), and lung cancers (875 to 1882 cancers), and Hodgkin lymphoma (426 to 897 cancers). In the HIV-only population in 34 US states, an estimated 2191 non-AIDS-defining cancers occurred during 2004-2007, including 454 lung, 166 breast, and 154 anal cancers. Over a 15-year period (1991-2005), increases in non-AIDS-defining cancers were mainly driven by growth and aging of the AIDS population. This growing burden requires targeted cancer prevention and treatment strategies.

              The evolution of the population-based cancer registry.

              D Parkin (2006)
              The idea of recording information on all cancer cases in defined communities dates from the first half of the twentieth century, and there has been a steady growth in the number of such cancer registries since. Originally, they were concerned primarily with describing cancer patterns and trends. Later, many were able to follow up the registered patients and calculate survival. In the last 20 years the role of registries has expanded further to embrace the planning and evaluation of cancer control activities, and the care of individual cancer patients. This Review looks at the current status of cancer registration practice and use from an international perspective, mindful that the registration of cancer has expanded into a global activity.
