Title: Acute Myeloid Leukemia with Recurrent Genetic Abnormalities, Part II: Mutations Involving CEBPA, NPM1, and RUNX1
Abstract: Cytogenetic studies have traditionally played one of the most important roles for the classification and risk stratification of acute myeloid leukemia (AML). AML patients with a favorable risk cytogenetic profile are associated with relatively good responses to chemotherapy-based regimens and high complete remission rates. AML patients with unfavorable cytogenetic risk profiles require allogeneic stem cell transplantation to improve prognosis. However, most AML cases have an intermediate prognosis and include approximately 50% of the AML cases that have a normal karyotype at diagnosis and cannot be further subclassified based on cytogenetics. In recent years, several recurrent molecular mutations discovered in AML have been proposed to establish better classification of prognosis in the intermediate cytogenetic risk category. Recent revisions in the current 2008 WHO Classification of Tumours of Haematopoietic and Lymphoid Tissues have resulted in adopting the provisional diagnostic entities "AML with mutated CEBPA" and "AML with mutated NPM1" as distinct entities, and adding "AML with mutated RUNX1" as a provisional diagnostic entity. This chapter will focus on the characteristic clinicopathologic features of AML with mutations in the CEBPA, NPM1, and RUNX1 genes.
