Summary:The use of conventional-dose salvage chemotherapy in The purpose of this study was to investigate the results patients with Hodgkin's disease who relapse after initial of high-dose therapy and autologous stem cell transcombination chemotherapy is associated with high plantation in adult patients with Hodgkin's disease in remission rates, especially if the initial CR duration is first relapse after chemotherapy, to determine the overlonger than 1 year. 1-5 However, long-term follow-up studall and progression-free survival, identify prognostic ies have shown that less than 20% of these patients achieve factors for outcome, and to define the role of conventional dose salvage therapy given prior to the high dose long-term disease-free survival. 6 regimen. A retrospective analysis of 139 adult patients High-dose therapy, with autologous stem cell transplanreported to the lymphoma registry of the European tation (ASCT), has been used extensively in patients with

We concluded that high-dose therapy and autocompared with historical series of conventionally treated logous stem cell transplantation is an effective strategy patients, and have again identified prognostic factors for for patients with Hodgkin's disease in first relapse after long-term disease-free survival, including duration of initial chemotherapy. These results suggest that it should be remission, disease bulk at the time of ASCT, and sensitivity used regardless of initial remission duration.
