BACKGROUND: T-cell immunophenotype constitutes an unfavorable prognostic factor in aggressive non-Hodgkin's lymphomas. High-dose chemotherapy with autologous stem-cell rescue (HDC/ASCT) is the best salvage therapy for patients with aggressive B-cell lymphomas. However, results with this therapy in peripheral T-cell lymphoma (PTCL) are not well defined. PATIENTS AND METHODS: From January 1990 to December 1999, 115 patients with PTCL underwent HDC/ASCT inside the Grupo Español de Linfomas/Trasplante Autólogo de Médula Osea (GEL-TAMO) registry. At diagnosis the median age was 41 years and 60% of patients presented with two or three risk factors from the adjusted International Prognostic Index (a-IPI). Thirty-two per cent of patients were transplanted in first complete response (CR), 62% in chemosensitive disease and 5% in refractory disease. RESULTS: Eighty-six per cent of the patients attained a CR and 5% a partial response (PR). With a median follow-up of 37 months (range 1-133), overall survival (OS), time-to-treatment failure (TTF) and disease-free survival (DFS) at 5 years was 56%, 51% and 60%, respectively; for the 37 patients transplanted in first CR, OS and DFS at 5 years were 80% and 79%, respectively. Lactase dehydrogenase (LDH), a-IPI and disease status pre-transplant were associated with outcome. CONCLUSIONS: More than half of patients with chemosensitive disease who were transplanted are expected to be alive at 5 years. We confirm the utility of the pre-transplant IPI system in predicting outcome. Salvage treatment results with HDC/ASCT in PTCL are similar to those found in corresponding aggressive B-cell lymphomas.
