Seven children underwent BMT for acute megakaryoblastic leukemia (AMKL). They were assessed for clinical, hematologic, and cytogenetic findings as well as response to treatment. The diagnosis of AMKL was established by cytochemistry, immunophenotyping and/or platelet-peroxidase reactivity. Patients had received various prior chemotherapies. One was in first remission, another in second remission and five were in relapse at the time of admission for transplant. Marrow donors included an HLA identical sibling (one), phenotypically HLA identical unrelated (two) and partially HLA identical family members (four). Five patients achieved engraftment, one rejected the graft and died on day 20 after a second unrelated transplant and one died from infection on day 5. Two patients relapsed within the first month after transplant and died of recurrent leukemia. Another died of a second malignancy on day 2232. Two patients survive disease-free more than 3.8 and 4.3 years after transplant.

The outcome of a cohort of 218 consecutive patients who failed to respond to a single course of standard daunorubicin plus ARAC (three + seven) induction regimen has been retrospectively evaluated to assess the characteristics of this group of AML patients and the effectiveness of second-line induction programs. Seventy-four of the 218 patients (33.9%) attained complete remission with salvage chemotherapies. The multivariate analysis of pretherapy characteristics of the patients showed that peroxidase positivity and age were the most important factors in determining whether or not the patient would have a favorable response to second-line induction regimen. In addition, comparison of marrow characteristics at diagnosis with those of marrow after the first-line therapy (marrow leukemic index, MLI) provided the greatest differences between second-line CR and resistant patients. Finally, peroxidase positivity and MLI predicted for remission duration and overall survival. Allogeneic BMT, however, appeared the most important factor for survival and event-free survival of remitting patients. These results are of importance when considering that better defined prognostic factors provide an objective rationale for selecting appropriate strategies for the treatment of patients who do not respond to a single course of induction regimen.
