Autologous Stem-Cell Transplantation for Poor-Risk and Relapsed Intermediate- and High-Grade Non-Hodgkin's Lymphoma

Academic Article


  • The primary objective of this study was to evaluate the outcome of patients treated with high-dose chemo-/radiotherapy or high-dose chemotherapy and autologous stem-cell transplant (ASCT) for relapsed, refractory, or poor-risk intermediate-grade (IG) and high-grade (HG) non-Hodgkin's lymphoma (NHL). The secondary objectives were to determine prognostic factors for relapse and survival. Between February 1987 and August 1998, 264 patients, 169 (64%) IG and 95 (36%) HG, underwent high-dose therapy and ASCT at City of Hope National Medical Center (COHNMC). There were 157 (59%) males and 107 (41%) females with a median age of 44 years (range, 5-69 years). The median number of prior chemotherapy regimens was 2 (range, 1-4), and 71 (27%) had received prior radiation as part of induction or as salvage therapy. The median time from diagnosis to ASCT was 10.8 months (range, 3-158 months). Ninety-four patients (36%) underwent transplantation in first complete/partial remission (CR/PR), 40 (15%) in induction failure, and 130 (49%) in relapse or subsequent remission. Two preparative regimens were used: total body irradiation/high-dose etoposide/cyclophosphamide (TBI/VP/CY) in 208 patients (79%) and carmustine/etoposide/cyclophosphamide (BCNU/VP/CY) in 56 patients (21%). One hundred sixty-three patients (62%) received peripheral blood stem cells (PBSC) and 101 (38%) received bone marrow (BM) alone or BM plus PBSC. At a median follow-up of 4.43 years for surviving patients (range, 1-12.8 years), the 5-year Kaplan-Meier estimates of probability of overall survival (OS), progression-free survival (PFS), and relapse for all patients are 55% (95% confidence interval [Cl]: 49%-61%), 47% (95% Cl: 40%-53%), and 47% (95% Cl: 40%-54%), respectively. There were 27 deaths (10%) from nonrelapse mortality, including seven (3%) patients who developed second malignancies (five with myelodysplasia/acute myelogenous leukemia and two with solid tumors). By stepwise Cox regression analysis, disease status at ASCT was the only prognostic factor that predicted for both relapse and survival. The 5-year probability of PFS for patients transplanted in first CR/PR was 73% (95% Cl: 62%-81%) as compared to 30% (95% Cl: 16%-45%) for induction failure and 34% (95% Cl: 26%-42%) for relapsed patients. Our results further support the role of high-dose therapy and ASCT during first CR/PR for patients with poor-risk intermediate- and high-grade NHL Early transplant is recommended for patients failing initial induction therapy or relapsing after chemotherapy-induced remission. Relapse continues to be the most common cause of treatment failure. An alternative approach to prevent relapse, the incorporation of radioimmunotherapy into the high-dose regimen, is being investigated. The development of a second malignancy is a serious complication of high-dose therapy, which requires close surveillance.
