Outcomes of Hodgkin's Lymphoma Patients with Relapse or Progression Following Autologous Hematopoietic Cell Transplantation

Patients with relapsed/progressed Hodgkin's lymphoma (HL) following autologous hematopoietic cell transplantation (AHCT) may not have an invariably dismal outcome as previously considered. In a multicenter retrospective study, we evaluated 126 patients who relapsed/progressed after a median of 5 (1-132) months post first AHCT. Management consisted of irradiation, chemotherapy ± irradiation, second HCT, or palliation. Currently, 53 of 126 (42%) patients are alive for a median of 32 months since relapse/progression and 44 (35%) of them remain progression-free. Interval of <12 months to relapse/progression, presence of B-symptoms, and disease refractoriness at first AHCT failure adversely influenced overall survival (P < .05). The type of treatment had no impact on survival. Furthermore, to predict the outcome at the time of relapse/progression, we constructed a prognostic model based on 3 factors: interval of <12 months from first AHCT to relapse/progression, presence of B-symptoms, and pre-AHCT disease refractoriness. Patients with 0 to 1 factors achieved a median survival of 70 months compared to 17 months only in those with 2 to 3 factors (P < .001). This study, the largest reported to date, suggests that selected patients with relapse/progression after first AHCT can be rescued with current treatment modalities. However, relapsed/progressed HL following AHCT still poses a therapeutic challenge, and prospective trials are needed to determine the most appropriate approach in this setting.
