Purpose: The role of classical prognostic factors (ie, age, performance status [PS], stage, extranodal involvement, and serum lactate dehydrogenase [LDH] level) included in the International Index for diffuse large-cell non- Hodgkin's lymphoma (NHL) of the general population is presently unknown in the setting of human immunodeficiency virus (HIV). To assess the prognostic value of these factors in HIV-related NHL, we reviewed the cohort of patients with HIV-related NHL diagnosed and treated with combination chemotherapy (CT) at our institution. Patients and Methods: Ninety-six patients with systemic HIV-related NHL diagnosed and treated with combination CT regimens between September 1987 and December 1993 at the Centro di Riferimento Oncologico, Aviano, Italy, were studied. All clinical and laboratory data were evaluated by univariate and multivariate analyses, using overall survival as the end point. Results: Complete remission (CR) occurred in 48% of patients; the overall median survival and disease-free survival times were 7 and 13 months, respectively. Among the classical and HIV-related prognostic factors, the following had a statistically significant influence on survival: PS ≤ 2, elevated LDH level, age greater than 40 years, a CD4 cell count less than 100/μL, active opportunistic infections at diagnosis of NHL, and B symptoms. Multivariate analyses showed that only age, serum LDH level, and CD4 cell count were independent predictors of shortened survival. The increased hazard for patients greater than 40 years of age was 1.6 (95% confidence interval [CI], 1.2 to 2.3), for patients with increased LDH it was 1.8 (95% CI, 1.01 to 3.1), and for patients with a CD4 cell count less than 100/μL it was 1.7 (95% CI, 1.01 to 2.9). Conclusions: Our study shows that in addition to HIV-related prognostic factors, ie, CD4 cell count less than 100/μL, classical prognostic factors such as age and serum LDH level are independent prognostic factors and should be included in the design of future clinical trials of HIV-related NHL.
