title: AIDS-related systemic non-Hodgkin's lymphoma at a large community program.
abstract: The introduction of triple antiretroviral therapy has led to reductions in opportunistic diseases in HIV-infected patients. However, little is known of the effect of this therapy on the clinical and pathological features and the outcome of patients with AIDS-related systemic non-Hodgkin's lymphoma (NHL). We examined the incidence and clinical manifestations of HIV-infected patients with systemic NHL at the Harris County Hospital District and Veterans Affairs Medical Center (Houston, TX). Between January 1996 and December 2000, 76 cases of systemic NHL were diagnosed in 3655 HIV-infected patients. Three groups of patients diagnosed with systemic NHL were identified according to their history of antiretroviral therapy: treatment naive (n = 20), dual nucleoside (n = 22), and triple antiretroviral drug-treated patients (n = 34). The median duration of antiretroviral therapy before the diagnosis of systemic NHL in the triple antiretroviral and dual nucleoside treatment groups was 12 versus 8 months (p < 0.0004). Thirty-five percent of patients (12 of 34) in the triple treatment group had an HIV RNA viral load of <400 copies/ml and their median CD4+ cell count was 301 cells/mm(3) (range, 46 to 667 cells/mm(3)) at the time of diagnosis of systemic NHL. More patients treated with triple antiretroviral therapy received complete courses of chemotherapy as compared with the other two groups (p = 0.013). However, the overall survival did not differ significantly among the three groups of patients. These data suggest that AIDS-related systemic NHL continues to occur even in patients treated with triple antiretroviral therapy. In addition, this opportunistic malignancy is associated with significant mortality. Therefore, it is necessary to develop a better understanding of the pathogenesis of this disease.
