Progress of studies on genetics of childhood acute leukemia / 中国实验血液学杂志

ABSTRACT

This study on determination of leukemia-specific chromosomal abnormalities and their relationship with prognosis of childhood acute leukemia (AL) had an important significance for childhood acute leukemia. In recent years, the efficacy of treatment of childhood AL has been greatly improved, but relapse is still a main factor affecting prognosis. Treatment based on the risk stratification by cytogenetic abnormalities can improve the prognosis and survival rate. In the past 3 decades, the genetic techniques have developed rapidly and many new genetic abnormalities have been found. This review highlights the main chromosomal and genomic abnormalities of 3 common childhood AL, including B-cell precursor acute lymphoblastic leukemia (BCP-ALL), T-cell acute lymphoblastic leukemia (T-ALL) and acute myeloid leukemia (AML).
