title: New strategies in the treatment of acute myelogenous leukemia: mobilization and transplantation of autologous peripheral blood stem cells in adult patients.
abstract: During the last decade high-dose Ara-C (HIDAC; single doses of 3 g/m(2)) and autologous stem cell transplantation have been increasingly used as postremission therapy in adult acute myelogenous leukemia (AML). Controlled clinical trials have demonstrated a long-term disease-free survival of 40%-50% for patients treated with at least two courses of HIDAC. Other studies have demonstrated that postremission autologous bone marrow transplantation results in a disease-free survival equal to or better than conventional chemotherapy. However, autotransplantation with mobilized peripheral blood stem cells (PBSC) would now be preferred instead of autologous bone marrow, due to the shorter hematopoietic reconstitution period. The results reviewed in the present article suggest that HIDAC and autologous PBSC transplantation can be combined in the postremission treatment of adult AML, and this combination therapy may also reduce minimal residual disease and the risk of posttransplant relapse. From the available studies it cannot be concluded whether graft purging further reduces the relapse risk. However, the possible advantage of combination therapy with repeated courses of HIDAC and autologous PBSC transplantation needs to be demonstrated in prospective clinical trials before it can be recommended as a part of the routine treatment in AML.
