Association of non-acquired immunodeficiency syndrome-defining cancers with human immunodeficiency virus infection.
Kaposi's sarcoma and non-Hodgkin's lymphoma were among the earliest recognized manifestations of the acquired immunodeficiency syndrome (AIDS) epidemic. Excluding these two tumors, the overall risk of all other cancers in human immunodeficiency virus (HIV)-infected individuals is similar to that of the general population. However, varying levels of evidence link several additional neoplasms to HIV infection. The evidence is strongest for an association with Hodgkin's disease, with lower relative and absolute risks than for non-Hodgkin's lymphoma. Anogenital intraepithelial neoplasia also appears to be HIV associated, but increases of invasive disease are still uncertain for both cervical and anal cancers. Various studies have suggested associations with testicular seminoma, multiple myeloma, oral cancer, and melanoma, but the data are inconsistent. Leiomyosarcoma and benign leiomyomas have increased in incidence in HIV-infected children but are unusual in HIV-infected adults. Conjunctival carcinoma is seen in HIV-infected individuals in sub-Saharan Africa but it is uncommon in Western countries. Most other cancers do not seem to have increased incidences in HIV infection. The etiologic mechanisms of HIV-related cancer likely differ among these diverse cancers and do not globally increase cancer risk.
