High-Dose Therapy And Autologous Stem Cell Transplantation In Relapsed And Refractory Hodgkin'S Disease: Outcome Based On A Prognostic Model

We evaluated the results of high-dose therapy (HDT) and autologous hematopoietic stem cell transplantation (ASCT) in patients with relapsed or primary refractory Hodgkin's disease (HD), using a previously reported prognostic model based on the presence of three poor prognostic factors at the start of salvage therapy/preparative regimen: B symptoms, extranodal disease and the duration of last complete response of less than 1 year. Based on this model, the patients were divided into low-risk and high-risk groups. Between 1993 and 2001, 24 patients with HD were treated with HDT and ASCT. Eighteen of the 24 patients had 0-1 risk factors (low-risk group) and 6 patients had 2-3 risk factors (high-risk group). Using Kaplan-Meier analysis, after a median follow-up of 40.5 months, the progression-free survival (PFS) was 48%, and the overall survival (OS) was 55%. PFS in the low-risk group was 56%, and in the high-risk group 17% (p < 0.001). OS in the low-risk group was 68% and in the high-risk group it was 18% (p < 0.001). The 100-day transplant-related mortality for the entire group was 16%. Our results are comparable to those reported in previous clinical trials for patients with refractory and relapsed HD treated with HDT and ASCT. The use of a prognostic model appears useful for predicting the outcome of HDT and ASCT for HD patients, and may play an important role in choosing the appropriate therapy for these patients.
