title: AIDS-related malignancies: the emerging epidemic.
abstract: The incidence of three malignancies has increased in conjunction with the epidemic of human immunodeficiency virus (HIV) disease, and they are currently considered acquired immunodeficiency syndrome (AIDS)-defining conditions. These are Kaposi's sarcoma, associated with AIDS since the onset of the epidemic in 1981; intermediate or high-grade B-cell lymphoma, which became AIDS-defining in 1985; and cervical carcinoma in HIV-infected women, formally recognized as an AIDS-defining diagnosis on January 1, 1993. Approximately 40% of all patients with AIDS have developed cancer during the course of HIV infection. Further, as survival has improved in HIV disease, the incidence of these malignancies has increased. It is thus expected that greater numbers of patients with AIDS-related lymphoma and cervical cancer will be diagnosed in the years ahead. The epidemiologic factors associated with neoplastic disease differ among patients with the three AIDS-related malignancies. The pathogenesis of neoplastic disease also differs. The specific etiologic steps in the development of AIDS-related Kaposi's sarcoma and lymphoma are currently unknown. However, a great deal of information has already been acquired, which may have bearing on the pathogenesis of malignant disease in general, as well as the elucidation of future therapeutic modalities. The specific epidemiologic, etiologic, and clinical characteristics of the AIDS-related malignancies will be described herein. It is hoped that this review will serve to outline our current understanding of this area, to introduce the questions and controversies which are apparent in the field, and to mention those areas in which future research might be focused.
