Real-World Outcomes of Autologous and Allogeneic Hematopoietic Stem Cell Transplantation for Relapsed/Refractory Hodgkin Lymphoma in the Era of Novel Therapies: A Canadian Perspective.

Despite high cure rates with frontline therapy for Hodgkin lymphoma (HL), approximately 30% of patients will relapse or develop primary refractory disease (R/r). Autologous hematopoietic stem cell transplantation (autoHSCT) is the standard of care for R/r disease, and allogeneic HSCT (alloHSCT) is a curative option for patients in second relapse. Novel agents are being incorporated for the treatment of R/r HL, such that the optimal timing of transplantation is currently being challenged. Because access to these new agents varies among transplantation centers, we sought to offer a Canadian perspective on the treatment of R/r HL and demonstrate the utility and effectiveness of both autoHSCT and alloHSCT for the treatment of R/r HL. This single-center retrospective study examined outcomes in 89 consecutive patients with R/r HL treated with autoHSCT between January 2007 and December 2019. A total of 17 patients underwent alloHSCT either as a tandem auto-allo approach or as salvage therapy. With a median follow-up of 5.0 years, the estimated 5-year PFS and OS for patients undergoing autoHSCT were 57.5% (95% confidence interval [CI], 45.2% to 68.0%) and 81.3% (95% CI, 70.0% to 88.8%), respectively. Corresponding values for patients who underwent alloHSCT were 76.5% (95% CI, 48.8% to 90.4%) and 82.4% (95% CI, 54.7% to 93.9%). Nonrelapse mortality at 0% at 100 days and 9.4% at 5 years post-autoHSCT and 0% and 5.9%, respectively, post-alloHSCT. The cumulative incidence of acute graft-versus-host disease (GVHD) at day +100 was 35.3% (95% CI, 17.7% to 62.3%), and that of chronic GVHD at 1 year was 23.5% (95% CI, 6.9% to 45.8%). Both autoHSCT and alloHSCT provide robust and prolonged disease control, and new agents should be used as a bridge to improve the curative potential of these definitive cellular therapies.
