A simplified method for stem cell autografting in multiple myeloma: a single institution experience.
In a 14-year period in a single institution 31 autografts were performed in 26 patients with multiple myeloma (MM), using a simplified and affordable autografting procedure: conducting the grafts on an outpatient basis and avoiding stem cell freezing. Autografts were started on an outpatient basis in all instances, but four patients were admitted to the hospital. Median time to achieve more than 0.5 x 10(9)/l granulocytes was 27 days, whereas median time to recover above 20 x 10(9)/l plts was 37 days. CR was achieved in 19 cases and a very good partial response in 6 cases. The 100-day mortality was 9.6%. The overall median post-transplant survival has not been reached, being above 76 months, whereas the 76-month survival is 80%. The median cost of each procedure was US$ 15 000. Survival results were substantially better than those of historical control in a group of patients treated in the same institution with melphalan/prednisone. It is concluded that high-dose therapy rescued with a simplified autologous stem cell graft is a valid, useful and affordable therapeutic option for patients with MM, even with economical restraints.
