We aimed to compare AIDS risk-adapted intensive chemotherapy in AIDS-related lymphoma (ARL) patients before and after the advent of highly active antiretroviral therapy (HAART). A total of 485 patients aged from 18 to 67 years were randomly assigned to chemotherapy after stratification according to an HIV score based on performance status, prior AIDS, and CD4(+) cell counts below 0.10 x 10(9)/L (100/mm(3)). A total of 218 good-risk patients (HIV score 0) received ACVBP (doxorubicin, cyclophosphamide, vindesine, bleomycin, and prednisolone) or CHOP (doxorubicin, cyclophosphamide, vincristine, and prednisolone); 177 intermediate-risk patients (HIV score 1), CHOP or low-dose CHOP (Ld-CHOP); and 90 poor-risk patients (HIV score 2-3), Ld-CHOP or VS (vincristine and steroid). The 5-year overall survival (OS) in the good-risk group was 51% for ACVBP versus 47% for CHOP (P = .85); in the intermediate-risk group, 28% for CHOP versus 24% for Ld-CHOP (P = .19); and in the poor-risk group, 11% for Ld-CHOP versus 3% for VS (P = .14). The time-dependent Cox model demonstrated that the only significant factors for OS were HAART (relative risk [RR] 1.6, P < .001), HIV score (RR 1.7, P < .001), and the International Prognostic Index (IPI) score (RR 1.5, P < .001) but not chemotherapy regimen. Our findings indicate that in ARL patients, HIV score, IPI score, and HAART affect survival but not the intensity of the CHOP-based chemotherapy.
