The interferons (IFN) are one of the body's natural defensive responses to such foreign components as microbes, tumors, and antigens. The IFN response begins with the production of the IFN proteins (alpha, beta, and gamma), which then induce the antiviral, antimicrobial, antitumor, and immunomodulatory actions of IFN. Recent advances have led to Food and Drug Administration approval of five clinical indications for IFN. Interferon alfa is approved for hairy-cell leukemia, condyloma acuminatum, Kaposi's sarcoma in the acquired immunodeficiency syndrome, and non-A, non-B (type C) viral hepatitis. Interferon gamma has properties distinctive from those of IFNs alpha and beta and is approved as an immunomodulatory treatment for chronic granulomatous disease. Promising clinical results with IFNs have also been reported for basal cell carcinoma, chronic myelogenous leukemia, cutaneous squamous cell carcinoma, early human immunodeficiency virus infection, hepatitis B, and laryngeal papillomatosis. Future clinical uses of IFNs may emphasize combination therapy with other cytokines, chemotherapy, radiation, surgery, hyperthermia, or hormones.

We are giving an overview over the clinical features and different therapeutic options of HIV associated malignancies. There are three AIDS-defining malignancies: - Kaposi's sarcoma - Non-Hodgkin's lymphoma (NHL) - cervical cancer. In Kaposi sarcoma there is a broad therapeutic spectrum from cryotherapy to systemic chemotherapy depending on the site and stage of the Kaposi sarcoma. In NHL early therapeutic intervention is necessary because of the fast progress of the tumor. The cervical cancer in HIV-infected women seems to be more aggressive than in non-infected and also needs early therapeutic intervention. Many other tumors seem to occur more frequently in patients with HIV infection: anorectal cancer, malignant testicular tumors, lung cancer, Hodgkin's lymphoma, basal cell carcinoma, squamous cell carcinoma, and even malignant melanoma. The cancer incidence in HIV-patients seems to be higher among nonblacks. Most of the immunodeficiency associated tumors are virus induced and they are accompanied by a persistent viral infection, including HHV-8 in Kaposi's sarcoma; Epstein Barr virus (EBV) in NHL; and human papillomavirus (HPV) in cervical cancer. But there are also types of virus induced tumors which are not frequently associated with HIV-infection like the primary hepatocellular carcinoma in patients with hepatitis B virus infection.
