Abstract

Introduction: Immunoglobulin D (IgD) and IgM multiple myeloma represent uncommon immunoglobulin isotypes, accounting for 2% and 0.5% of cases, respectively. Limited information is available regarding the prognosis of these isotypes, but they have been considered to have a more aggressive course than the more common immunoglobulin G (IgG) and IgA isotypes. In particular, the outcome after autologous hematopoietic stem cell transplantation (auto-HCT) has not been well defined. Patients and Methods: Using the Center for International Blood and Marrow Transplant Research (CIBMTR) database, we identified 36 patients with IgD and 11 patients with IgM myeloma among 3578 myeloma patients who received intensive therapy and auto-HCT over a 10-year period. Results: The progression-free and overall survival probabilities at 3 years were 38% (95% CI, 21%-56%) and 69% (95% CI, 51%-84%) for IgD myeloma, and 47% (95% CI, 17%-78%) and 68% (95% CI, 36%-93%), respectively, for IgM disease. Although formal statistical analysis was limited by the small sample size, these results were comparable to those for IgG and IgA patients autografted during the same time period. Transplantation-related mortality and disease relapse/progression of myeloma were also similar for all isotypes. Conclusion: This analysis demonstrates comparable outcomes in all immunoglobulin isotypes. Therefore, auto-HCT should be offered to eligible patients with IgD and IgM myeloma.
