Incidence and Prevalence of Cancer in People Living With HIV/AIDS at Cancer Centers in Latin America

PRIMARY OBJECTIVES: I. To determine the number of diagnosed cancers in people living with HIV/AIDS (PLWHA) presenting to participating clinical sites in Latin America, and estimate site-specific prevalence based on all presenting cancers (new diagnosis, recurrence, and surveillance cases) and site-specific incidence based on newly diagnosed cancers. SECONDARY OBJECTIVES: I. Obtain information on the use of diagnostic testing and treatment for the cohort of diagnosed HIV-associated cancer participants. II. To collect information on participant characteristics for diagnosed HIV-associated cancers (e.g., antiretroviral therapy \[ART\] regimen, current CD4 count, current viral load, etc.). OUTLINE: Patients respond to surveys and/or undergo medical record review at baseline and at 4 weeks.
