Long-term follow-up of T cell-depleted allogeneic bone marrow transplantation in refractory multiple myeloma: importance of allogeneic T cells

Multiple myeloma may be cured by myeloablative conditioning and allogeneic blood or marrow transplantation (alloBMT), but this occurs at the expense of high transplant-related mortality. In an endeavor to reduce procedure-related toxicity, this study retrospectively evaluated the safety, tolerability, and efficacy of T cell depletion by counterflow centrifugal elutriation before alloBMT. Fifty-one patients with stage II (6) or III (45) multiple …
