Non—AIDS–Defining cancers and HIV infection

Abstract

With fewer patients now succumbing to infectious complications of AIDS, other HIV-related morbidities such as malignancies have become increasingly important. Apart from Kaposi’s sarcoma, non-Hodgkin’s lymphoma, and cervical cancer, which are considered as AIDS-defining, several additional cancers, referred to as non-AIDS-defining cancers, are also statistically increased in HIV-infected persons. These include Hodgkin’s disease, anal carcinoma, lung cancer, nonmelanomatous skin cancer, and testicular germ cell tumors, among others. However, the types of cancer observed at an increased frequency and the relative risks reported vary widely among studies. Although immunosuppression is consistently associated with an increased risk of AIDS-related malignancies, the role of immunosuppression in the pathogenesis of non-AIDSdefining cancers is controversial. Although data regarding the optimal management of these cancers are lacking, current studies suggest that patients with HIV-associated malignancies should be treated with similar approaches to those of their counterparts in the general population.
