title: Acute myelogenous leukemia at Baylor Charles A. Sammons Cancer Center, 2010 to 2012: retrospective analysis of molecular genetic evaluation.
abstract: Over the last several decades, advancements in the understanding of genetic and molecular origins of acute myeloid leukemia (AML) have brought about significant changes in how the disease is classified, diagnosed, and treated. The change from the traditional French-American-British classification system to that of the World Health Organization redefined how the disease is diagnosed not only morphologically but genetically. With genetic information proving to have prognostic value, the newer classification system, which incorporates results of cytogenetic and molecular analyses, allows better definition of disease and risk stratification, ultimately guiding treatment choices. As understanding and advancements in the molecular basis of AML continue to grow and influence patient management, the importance of an accurate and thorough initial patient evaluation is paramount. We performed a review of AML cases diagnosed at Baylor Charles A. Sammons Cancer Center from February 2010 to December 2012 to assess the thoroughness of initial diagnostic evaluations based on current guidelines, including up-to-date molecular analyses for mutations in NPM1, CEBPA, FLT3, and C-KIT. Results showed that patients newly diagnosed with AML undergo thorough diagnostic evaluation in keeping with current recommendations, and many had further genetic and molecular evaluations, which although considered optional or investigational, have prognostic significance. We identified potential areas of improvement for making this diagnostic evaluation more specific to the patient and the patient's disease. Currently, we are investigating having patients undergo reflex genetic testing if they meet certain criteria to better define their specific disease while avoiding unnecessary genetic evaluations that come at increased cost.
