The occurrence of opportunistic non-Hodgkin's lymphomas in the setting of infection with the human immunodeficiency virus

Abstract

The incidence of non-Hodgkin's lymphoma (NHL) has increased by over 50% in the United States since 1973. There is epidemiologic evidence that some of this increase is the result of AIDS-related lymphoma and that this component is increasing. Prolonged survival in the setting of a variety of immunodeficiency states is associated with an increased incidence of NHL. The development of antiretroviral therapy and improved therapy for the complications of AIDS has resulted in prolonged survival of patients with AIDS. As these patients survive longer with profound immunodeficiency, they have an increased cumulative risk of developing NHL. This may result in even more AIDS-related NHL in the future than predicted from current epidemiological studies. An increased understanding of the pathogenesis of AIDS-related NHL may lead to means of preventing their occurrence. Also, therapies that may prevent immunodeficiency from developing in HTV-infected patients may reduce the likelihood of NHL developing. Current efforts at treating these lymphomas are aimed at preventing the myelo-suppression and immunosuppression associated with current regimens, lymphoma relapses within the central nervous system, and the opportunistic infections associated with treatment of these tumors. Ultimately, the best means of preventing the development of these lymphomas is by preventing infection with HTV.
