Allogeneic BMT for AML

Because allogeneic bone marrow transplantation is the only therapy capable of achieving cure in patients with AML who fail induction therapy,1,2 all patients 55 years of age or less with newly diagnosed AML and their families should be HLA-typed soon after diagnosis to enable transplantation should induction fail. Allogeneic transplantation is indicated in patients in second remission and in untreated first relapse, since the results (see table below) are superior to those achieved without transplantation3-5 Patients transplanted in first remission achieve the highest cure rates.

Numerous prospective studies have compared marrow transplantation in patients with HLA-matched siblings to chemotherapy in patients without such siblings (see table below). However, there have been important advances in both chemotherapy and transplantation since the conduct of most of these studies. In addition, these studies did not distinguish between different categories of patients. Retrospective studies have suggested that there may be certain categories of patients for whom transplantation may be a particular advantage and others for whom it may be of less benefit. Finally, it remains untested whether a strategy of transplantation in first remission is superior to the combination of initial chemotherapy followed by transplantation as salvage therapy.

|Autologous marrow transplantation
Autologous marrow transplantation for patients with AML in first and second remission in several phase II studies has yielded promising results.23-27 In the largest prospective randomized study so far reported, 569 patients with AML in first remission were assigned to allogeneic transplantation if HLA-matched siblings were available, or were randomized to autologous transplantation or continued chemotherapy if donors were not available.28 Promising results were obtained with transplantation as compared to chemotherapy.
- Study results of allogeneic bone marrow transplantation are most favorable in patients transplanted in first remission.
- All patients 55 years of age or less with newly diagnosed AML should be HLA-typed soon after diagnosis, since allogeneic BMT is the only therapy to achieve cure (estimated in 15% to 20% of patients studied)1-7 should induction therapy fail.
- Results of a large, prospective randomized study of patients in first remission confirm findings of earlier prospective studies that allogeneic bone marrow transplantation improves disease-free survival compared to chemotherapy.
