Immunotherapy by non-myeloablative allogeneic stem cell transplantation in multiple myeloma: results of a pilot study as salvage therapy after autologous transplantation.

| Abstract |
Non-myeloablative allogeneic stem cell transplantation has been reported to induce sustained complete remission even in advanced diseases (acute leukemia, lymphomas). The tolerance of this procedure allows treatment of poor candidates to conventional allogeneic transplantation with persisting or relapsing myeloma patients. Twelve patients previously treated with at least VAD regimen and autologous transplantation were included. All patients had a serum beta2 microglobuline >3 mg/l at diagnosis. The conditioning regimen consisted of fludarabine 25 mg/m/day x 5, antithymoglobulin 2.5 mg/kg/day x 5, busulphan 2 mg/kg/day x 2; the transplant was peripheral stem cells (except one) from an HLA-matched sibling and was followed by cyclosporin for 45 to 90 days. This treatment results in a well-tolerated procedure (no mucositis, duration of aplasia <7 days). A dramatic graft anti-myeloma effect is documented even in progressive disease (11/12 PR + CR, 4/12 CR). However, five patients underwent CMV disease, one died of CMV encephalitis (UPN 3) and delayed severe GVHD occurred in four patients. Our data suggest that a better survival could be achieved when patients are transplanted with a controlled disease. In high risk patients, we now propose a non-myeloablative transplantation in addition to the conventional and intensive chemotherapy as first-line of treatment.
