A reduced intensity conditioning regimen for allografting following autografting is feasible and has strong anti-myeloma activity.

Sixteen patients with stage III multiple myeloma (MM) and a median age of 51 years were treated with autografting followed by reduced intensity conditioning allotransplantation (RICT). Nine patients are alive in remission at a median of 30 months after their transplants, one patient is alive in relapse and 6 patients died of progressive disease (5) or extensive chronic graft-versus-host disease, infections and progressive disease (1). We suggest that this two-step approach is feasible and it has strong anti-myeloma activity.
