[Reseach Progress of Ki-67 in Acute Myeloid Leukemia-Review].

Ki-67 antigen expression is closely associated with the cell cycle. Its expression is in almost the entire mitosis in cell cycle. Detection of Ki-67 antigen can reflect the cell proliferation activity in hematological malignancies. Detection of Ki-67 has been widely applied in staging, therapy effect monitoring and prognosis judgment in lymphoma. There has been a lot of studies investigating the expression of Ki-67 in acute lymphocytic leukemia (ALL) and chronic lymphocytic leukemia (CLL), and investigating the relevance between Ki-67 expression and therapy effect and prognosis. However, there are a few studies about Ki-67 in acute myeloid leukemia (AML), and the results of studies are no consistant. In this review, the architecture, intracellular localization, expression regulation, physiological functions of Ki-67 and the application of Ki-67 in AML are summarized so as to understanding whether Ki-67 can play roles in diagnosis and prognostic evaluation of AML.
