Abstract
The role of stem cell transplantation (SCT) for patients with Waldenström’s macroglobulinemia (WM) remains undetermined. Therefore, we retrospectively evaluated the outcome of autologous and allogeneic SCT for patients with WM using the registry database of the Japan Society for Hematopoietic Cell Transplantation. Forty-six patients receiving autologous and 31 receiving allogeneic SCT were analyzed. The allogeneic SCT group included more patients with advanced disease status at transplant and received more lines of chemotherapy. The cumulative incidences of non-relapse mortality (NRM) at 1 year were 30.0% (95% CI, 14.7–46.9%) in the allogeneic SCT and 0% in the autologous SCT group. The estimated 3-year overall (OS) and progression-free (PFS) survival rates were 84.5% (95% CI, 66.0–93.4%) and 70.8% (95% CI, 53.0–82.9%) in the autologous SCT group, and 52.2% (95% CI, 32.5–68.6%) and 45.0% (95% CI, 26.3–62.0%) in the allogeneic SCT group. No patients died after the first 2 years following allogeneic SCT. In univariate analyses, disease status at SCT was significantly associated with PFS in autologous SCT, and with OS and PFS in allogeneic SCT. These results suggest that both autologous and allogeneic SCT have each potential role in WM. Allogeneic SCT is more curative for WM, but is associated with high NRM.Keywords
