High-dose therapy and autologous stem cell rescue for patients with Hodgkin’s disease in first relapse after chemotherapy: results from the EBMT

Abstract

The purpose of this study was to investigate the results of high-dose therapy and autologous stem cell transplantation in adult patients with Hodgkin’s disease in first relapse after chemotherapy, to determine the overall and progression-free survival, identify prognostic factors for outcome, and to define the role of conventional dose salvage therapy given prior to the high dose regimen. A retrospective analysis of 139 adult patients reported to the lymphoma registry of the European Group for Blood and Marrow Transplantation (EBMT) between February 1984 and July 1995 is considered. Data on all patients were reviewed and prognostic factors determined in univariate analysis. The actuarial 5-year overall survival (OS) and progression-free survival (PFS) for the entire group of 139 patients were 49.4 and 44.7%, respectively. In univariate analysis for OS, disease bulk at the time of high-dose therapy, second-line regimen, initial remission duration and status at transplant had no predictive value. Status at transplant was predictive for OS when patients in second complete remission (CR) were analysed separately from those in chemosensitive relapse. Similar trends were observed for PFS. We concluded that high-dose therapy and autologous stem cell transplantation is an effective strategy for patients with Hodgkin’s disease in first relapse after chemotherapy. These results suggest that it should be used regardless of initial remission duration. The role of conventional-dose salvage given prior to high-dose therapy is unclear, since disease status, disease bulk at the time of transplantation, and the second-line regimen had no significant effect on outcome. However, in view of the low patient numbers, no firm conclusion is possible, and this issue requires prospective assessment.
