Frontline Therapy with Early Intensification and Autologous Stem Cell Transplantation versus Conventional Chemotherapy in Unselected High-Risk, Aggressive Non-Hodgkin’s Lymphoma Patients: A Prospective Randomized GEMOH Report

Abstract

This prospective multicenter randomized trial compares conventional with early intensification with high-dose sequential chemotherapy (HDS) and autologous stem cell transplantation (ASCT) as frontline therapy in high-risk non-Hodgkin lymphomas (NHL). Newly diagnosed patients with aggressive high-risk [intermediate-high (HI) and high-risk (HR)] NHL according to the international prognosis index (IPI) were randomized to receive 12-week VACOP-B (arm A, 27 patients) or 6-week VACOP-B followed by HDS and ASCT (arm B, 29 patients). Complete remission rate was 52% in arm A and 55% in B. Nine patients (16%) died early due to progression. According to intention-to-treat, with a median follow-up of 23 months, the 5-year actuarial overall survival, progression-free survival and disease-free survival in arms A and B were 47 and 40% (p = nonsignificant), 47 and 30% (p = nonsignificant), and 97 and 47% (p = 0.02), respectively. Abbreviated chemotherapy followed by intensification with HDS-ASCT does not seem to be superior to conventional chemotherapy in HI/HR aggressive NHL.
