[Treatment of patients with relapsed/refractory Hodgkin lymphoma].

BACKGROUNDS

This retrospective study evaluated treatment outcomes in patients undergoing autologous stem cell transplantation (ASCT) for relapsed/refractory Hodgkin lymphoma (HL).

PATIENTS AND METHODS

Overall, 194 HL patients treated with ASCT between 2000 and 2009 were analyzed. Survival was calculated using Kaplan-Meier method and differences in survival between subgroups with log-rank test.

RESULTS

Best responses observed after ASCT: 124 complete and 35 partial remissions, 2 patients with stable disease and 33 relapses/progressions. During a median follow-up of 44 months, seventy patients after ASCT progressed/relapsed. Thirty-seven patients received salvage chemotherapy only with or without radiotherapy, 25 underwent allogeneic stem cell transplantation (SCT), 4 the second ASCT and 4 refused treatment. 5-year overall survival after ASCT was 71% and progression-free survival 54%. Median survival of the 70 patients relapsing after ASCT was 16.9 months. Median survival in patients after allogeneic SCT was 31.8 months and 12.4 months in patients treated with other modalities (p = 0.21). Overall mortality was 26.3% (51/194 patients): 13.4% progressions/relapses of HL and 12.9% non-relapse mortality.

CONCLUSION

Efficacy of ASCT was confirmed in 54% progression-free survivors. Median survival after ASCT failure is relatively short. There is a slightly longer overall survival after allogeneic SCT, although not statistically significant when compared to other approaches.
