The conference comes at a time when malignancies are emerging as an epidemic within the larger AIDS epidemic. It has been estimated that about 40 percent of all AIDS patients may eventually develop cancer.

Studies in this area have expanded over the past few years, and some have now begun to uncover the viral, genetic, and biochemical mechanisms that underlie these malignancies. A number of studies are also exploring new treatments.

Conference topics include:

• The recently discovered human herpes virus 8/Kaposi's sarcoma herpes virus and its relationship to Kaposi's sarcoma and lymphoma.
• The human papillomavirus (HPV) and cervical cancer in women and anal cancer in men with HIV infection.
• The influence of cytokines and growth factors on the course of AIDS related malignancies.
• The role of angiogenesis in Kaposi's sarcoma.
• Experimental treatments for AIDS related malignancies including new chemotherapy agents, immune-based therapy, and pilot studies of gene therapy.
• Pediatric cancers and AIDS.
