Acute myeloid leukemia (AML) is a heterogeneous hematologic malignancy characterized by the clonal expansion of myeloid blasts in the peripheral blood, bone marrow, and/or other tissues. It is the most common form of acute leukemia among adults and accounts for the largest number of annual deaths from leukemias in the United States. Like AML, blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a myeloid malignancy. It is a rare malignancy characterized by the aggressive proliferation of precursors of plasmacytoid dendritic cells that frequently involves the bone marrow, skin, central nervous system, and other organs and tissues. This discussion section focuses on the diagnosis and management of BPDCN as outlined in the NCCN Guidelines for AML.

The NCCN Guidelines for Acute Myeloid Leukemia (AML) provide recommendations for the diagnosis and treatment of adults with AML based on clinical trials that have led to significant improvements in treatment, or have yielded new information regarding factors with prognostic importance, and are intended to aid physicians with clinical decision-making. These NCCN Guidelines Insights focus on recent select updates to the NCCN Guidelines, including familial genetic alterations in AML, postinduction or postremission treatment strategies in low-risk acute promyelocytic leukemia or favorable-risk AML, principles surrounding the use of venetoclax-based therapies, and considerations for patients who prefer not to receive blood transfusions during treatment.

Acute myeloid leukemia (AML) is the most common form of acute leukemia among adults and accounts for the largest number of annual deaths due to leukemias in the United States. Recent advances have resulted in an expansion of treatment options for AML, especially concerning targeted therapies and low-intensity regimens.

These suggested practice guidelines are based on extensive evaluation of the reviewed risk-based data and indicate useful current approaches for managing patients with MDS. Four drugs have recently been approved by the FDA for treating specific subtypes of MDS: lenalidomide for MDS patients with del(5q) cytogenetic abnormalities; azacytidine and decitabine for treating patients with higher-risk or nonresponsive MDS; and deferasirox for iron chelation of iron overloaded patients with MDS. However, because a substantial proportion of patient subsets with MDS lack effective treatment for their cytopenias or for altering disease natural history, clinical trials with these and other novel therapeutic agents along with supportive care remain the hallmark of management for this disease. The role of thrombopoietic cytokines for management of thrombocytopenia in MDS needs further evaluation. In addition, further determination of the effects of these therapeutic interventions on the patient's quality of life is important.(116,119,120,128,129) Progress toward improving management of MDS has occurred over the past few years, and more advances are anticipated using these guidelines as a framework for coordination of comparative clinical trials.

Chemotherapy-induced neutropenia can cause complications that result in dose reductions or treatment delays that can, in turn, compromise clinical outcomes. Although the prophylactic use of colony-stimulating factors (CSFs) can reduce the risk, severity, and duration of severe and febrile neutropenia, they are not routinely administered to all patients undergoing myelosuppressive chemotherapy because of the costs. Selective use may, however, enhance their cost-effectiveness. These guidelines discuss the preventative or prophylactic use of recombinant human granulocyte-CSF to reduce the incidence, length, and severity of chemotherapy-related neutropenia and and prevent life-threatening complications.

The myelodysplastic syndromes (MDS) represent myeloid clonal hemopathies with relatively heterogeneous spectrums of presentation. The major clinical problems in these disorders are morbidities caused by patients' cytopenias and the potential for MDS to evolve into acute myeloid leukemia (AML). Managing MDS is complicated by the generally advanced age of the patients (median ages range from 65–70 years), the attendant non-hematologic comorbidities, and older patients' relative inability to tolerate certain intensive forms of therapy. In addition, when the illness progresses into AML, these patients experience lower response rates to standard therapy than patients with de novo AML.
