ABSTRACT
Between June 1979 and October 1983, 14 autografts were performed in 13 patients with CML (ten blast crisis, four accelerated phase). Results were disappointing four patients died during aplasia; seven returned to chronic phase, but three died of hemorrhage, four relapsed, and three did not reverse. The main problem was the very low rate of successful engraftment. Both the collection of bone marrow after treatment with busulfan and a particular sensitivity of CFU-GM to cryoinjury were responsible for the infusion of very low doses of CFU-GM. However, we observed some promising results:
In one patient in acute blast crisis, the Ph 1 chromosome disappeared, as well as the cytogenetic marker of transformation; in another patient with acute pure cytogenetic acceleration, the abnormal clone disappeared for 27 months; a third patient was maintained in a second chronic phase for 20 months. Thus we suggest that the results of autografting in chronic myeloid leukemia would be improved by infusing the largest possible dose of stem cells collected before or long after treatment by busulfan, and freezing them following a careful program.
