Patients with Hodgkin lymphomas progressing after autologous stem cell transplantation (SCT) have a very poor outcome. Our retrospective analysis confirms that reduced-intensity conditioning allogeneic SCT may be an effective salvage strategy for patients who relapse after an autologous SCT and that outcomes are similar for both sibling and matched-unrelated donor transplants. Patients with active disease at transplantation have poor outcomes. Background: Hodgkin lymphoma (HL) is a potentially curable disease, and modern therapy is expected to successfully cure more than 80% of the patients. However, patients progressing after intensive treatments, such as autologous stem cell transplantation (SCT), have a very poor outcome. Allogeneic SCT offers the only strategy with a curative potential for these patients. This study reports a retrospective multicenter experience of the Rete Ematologica Pugliese (REP) over the past 17 years, aiming to define the impact of each patient's disease and transplant-related characteristics on outcomes. Patients and Methods: We retrospectively studied 72 patients with HL who received allogeneic SCT from 2000 to 2017. At the time of allogeneic SCT, 33 (46%) patients had chemosensitive disease, and 39 (54%) were chemo-refractory. All patients received reduced-intensity conditioning, 50% received grafts from a matched sibling donor, and 50% from a matched-unrelated donor. Results: With a median follow-up of 48 months (range, 3-195 months), 30 patients are alive, and 42 have died. The Kaplan-Meier estimates of overall survival and progression-free survival at 5 years were 35% and 34%, respectively. Following transplantation, 12 (17%) patients died of non-relapse mortality at a median of 90 days (range, 1 day-20 months). The causes of death included infection (n = 7), graft-versus-host disease (n = 3), and multi-organ failure (n = 2). Conclusions: Allogeneic SCT results extend survival in selected patients with relapsed/refractory HL, showing low treatment-related mortality. Patients with active disease at the time of allogeneic transplantation have poor outcomes. Allogeneic SCT may be an effective salvage strategy for patients who relapse after an autologous SCT.
