Autologous bone marrow transplantation in a child with acute promyelocytic leukemia in second remission.

| Abstract |
Acute myeloid leukemia (AML) comprises 15%-20% of childhood acute leukemia cases. The long-term disease free survival (DFS) in childhood AML is poor with standard chemotherapy alone. Early intensive chemotherapy is generally regarded to be necessary for achieving high complete remission (CR) rates. Recent experience has shown that incorporation of early intensification with high-dose melphalan conditioning and autologous bone marrow transplantation (BMT) during the first remission significantly improves long-term DFS in children with AML. In this article, we report the use of autologous BMT for treatment of a three-and-half year old child with acute promyelocytic leukemia (APL or M3) in second remission. The patient was conditioned with high-dose melphalan of 180 mg/kg prior to bone marrow reinfusion. A total of 4.0 x 10(7)/kg mononuclear cells and 1.07 x 10(5)/kg granulomonocytic colony forming units (CFU-GM) were infused. Haematopoietic stem cells were enriched by almost 20-fold after the separation and cryopreservation procedures. Haematological recovery was achieved four-and-a-half weeks post-BMT. She has remained in complete remission 18 months after transplantation. Our experience in this patient indicates that this procedure can be used in second remission and it may provide a better alternative for the management of childhood AML in Singapore.
