Abstract

After the introduction of highly active antiretroviral therapy (HAART), intensive treatment, including high-dose therapy (HDT) and peripheral blood stem cell transplantation (PBSCT), has become feasible in HIV-positive patients with Hodgkin (HL) and non-Hodgkin (NHL) lymphoma. Herein, we report the long-term results, on an intention-to-treat basis, of a prospective study on HDT and PBSCT in 50 HIV-positive HAART-responding patients with refractory/relapsed lymphoma. After debulking therapy, 2 patients had early toxic deaths, 10 had chemoresistant disease, 6 failed stem cell mobilization, 1 refused collection, and 4 progressed soon after PBSC harvest. Twenty-seven actually received transplant. Twenty-one patients are alive and disease-free after a median follow-up of 44 months (OS, 74.6%; PFS, 75.9%). Only lymphoma response significantly affected OS after transplantation. In multivariate analyses both lymphoma stage and low CD4 count negatively influenced the possibility to receive transplant. Median OS of all 50 eligible patients was 33 months (OS, 49.8%; PFS, 48.9%). Low CD4 count, marrow involvement, and poor performance status independently affected survival. PBSCT is a highly effective salvage treatment for chemosensitive AIDS-related lymphoma. It seems rational to explore its use earlier during the course of lymphoma to increase the proportion of patients who can actually receive transplant.
