| Summary: | 碩士 === 國立中山大學 === 生物科學系研究所 === 100 === Acute myeloid leukemia (AML) is a highly heterogeneous disorder that results from a block in the differentiation of hematopoietic progenitor cells along with uncontrolled proliferation. In approximately 60% of cases, specific recurrent chromosomal
aberrations can be identified by modern cytogenetic techniques, and is an important indicator to classify patients into three prognostic categories: favorable, intermediate, and poor risk. Currently, favorable risk patients are usually treated with chemotherapy while poor risk patients receive allogeneic stem cell transplantation. However, the largest subgroup of AML patients (approximately 40%) has no identifiable cytogenetic abnormalities and is classified as intermediate risk. In this special subgroup of patients, a number of studies have demonstrated the relationship between different translocations involving the mixed lineage leukemia (MLL) gene and patient
prognosis. The heterogeneity of MLL-rearranged AML is reflected by the identification of more than 70 different fusion partners of this gene and the panel is continuously increasing. The aim of this study is to develop a sensitive molecular profiling test for relevant risk stratification that can help in the decision of treatment and/or follow-up strategy.
