Feasibility and efficacy of high-dose melphalan, cyclophosphamide, etoposide, and dexamethasone (LEED) chemotherapy with or without rituximab followed by autologous stem cell transplantation for aggressive and relapsed non-Hodgkin's lymphoma.
To investigate the feasibility and efficacy of high-dose chemotherapy (HDCT) followed by autologous stem cell transplantation (ASCT) for patients with newly diagnosed aggressive and relapsed non-Hodgkin's lymphoma (NHL), we administered LEED, a drug-only HDCT regimen consisting of melphalan, cyclophosphamide, etoposide, and dexamethasone, followed by ASCT in this single-institution trial. Furthermore, rituximab was added to the LEED regimen (R-LEED) for patients with CD20+ NHL. Twenty-six patients in the LEED group and 24 patients in the R-LEED group were enrolled and assessed for this study. All patients achieved complete engraftment after ASCT. As for the nonhematologic toxicities, infection toxicities of grades 3 and 4 were observed in 9 patients (34.6%) of the LEED group and 12 patients (50%) of the R-LEED group. Four patients (15.4%) in the LEED group and 5 (20.8%) in the R-LEED group developed grade 3 toxicity in the elevation of aspartate aminotransferase/alanine aminotransferase levels. Other grade 4 toxicities were rare in both groups. With a median follow-up time from the date of ASCT of 30 months in the LEED group and 18 months in the R-LEED group, the overall survival rates were 66.5% and 78.2%, respectively. These results suggested that LEED, as well as R-LEED, was a safe and feasible high-dose regimen for aggressive and relapsed NHL.
