Autologous and allogeneic stem‐cell transplantation for transformed Waldenström macroglobulinemia.

B Introduction: b The prognosis of histological transformation (HT) in Waldenström macroglobulinemia (WM) is unfavourable despite the use of diffuse large B-cell lymphoma-directed chemo-immunotherapy. B Methods: b Patients who received autoSCT or alloSCT between January 1996 and December 2021 were identified in an international multicenter database of 285 patients with transformed WM. The aim of this study was to evaluate the outcomes after autologous stem-cell transplantation (autoSCT) or allogeneic stem-cell transplantation (alloSCT) in patients with transformed WM.
