Summary
Introduction
One of the goals of modern leukemia research has been to gain a clearer understanding of the nature of the underlying molecular genetic lesions responsible for the establishment of the leukemic clone. This pursuit is fueled by the hope that the information obtained will not only help us understand the variability in clinical response that is observed among leukemia patients, but will also lead to the identification of rational molecular targets for novel chemotherapeutic agents. This goal is starting to be realized through recent advances in our understanding of the pathogenesis of acute myeloid leukemia (AML). Specifically, molecular genetic and genomic data are beginning to provide the initial framework for the subclassification of AML into clinically meaningful subgroups, and rationally designed compounds that inhibit novel molecular targets in leukemic cells are beginning to be assessed clinically for their utility as antileukemic therapeutics.
In this chapter, we provide a summary of the recent advances that have been made in elucidating the molecular genetic lesions involved in the pathogenesis of de novo AML. Our approach is to describe the structure of identified genetic lesions and explain at a molecular level how these alterations lead to cellular transformation. Because of the distinct clinical and biologic differences that exist between de novo AML and myelodysplasia-related AML, we largely restrict our discussion to de novo AML, which lacks any evidence of a prior or concurrent myelodysplastic phase.
