Effective use of intensive treatment against multiple myeloma of recipient origin after allogeneic transplantation for acute myeloid leukemia.

ABSTRACT

We describe here a 56-years -old woman cured in our institution for an acute myeloid leukemia (AML) and a monoclonal gammopathy of undetermined significance (MGUS). In order to treat AML, underwent allogeneic stem cell transplantation in second complete remission. Four years after transplant, MGUS evolved to multiple myeloma and was intensively treated with "autologous" transplant after successful mobilization. This report illustrates (i) a lack of efficacy of graft versus myeloma effect in a patient probably cured of AML by graft versus leukaemia effect; (ii) the ability to mobilize peripheral blood stem cells in order to perform "autologous" transplantation after allogeneic transplantation.
