Brief summary

This pilot phase I trial studies how well positron emission tomography (PET)/magnetic resonance imaging (MRI), fludeoxyglucose F-18 (18F-FDG) PET/computed tomography (CT), and whole body MRI work in finding extramedullary myeloid leukemia in patients with newly diagnosed acute myeloid leukemia. Extramedullary myeloid leukemia is a type of cancer found outside of the bone marrow and can be hard to detect with routine bone marrow monitoring, such as bone marrow aspirations. Diagnostic procedures, such as PET/MRI, 18F-FDG PET/CT and whole body MRI, may help find and diagnose extramedullary myeloid leukemia in patients with newly diagnosed acute myeloid leukemia.

Detailed description

PRIMARY OBJECTIVE: I. To estimate the incidence of extramedullary myeloid leukemia (EML) in patients with newly diagnosed acute myeloid leukemia (AML), including acute promyelocytic leukemia (APL), by imaging criteria using PET/MR (magnetic resonance), whole body MR, and PET/CT. SECONDARY OBJECTIVES: I. To qualitatively and quantitatively assess PET/MR and PET/CR that will be performed with and without fiducial markers, and to correlate these findings with clinical outcomes of treatment response, relapse, and patterns of relapse. II. Correlate findings of EML as in the primary objectives with clinical outcomes of treatment response, relapse, and patterns of relapse including location of relapse compared to site of EML. OUTLINE: Patients receive gadolinium intravenously (IV) and undergo whole body PET/MRI comprising diffusion weighted imaging and 3-dimentional (3D) fast spoiled gradient echo dual echo (FSPGR-DE) with and without fiducial markers. Patients then undergo 18F-FDG PET/CT before start treatment for acute myeloid leukemia. After completion of study, patients are followed up periodically.

Design outcomes

Primary

MeasureTime frameDescription
Incidence of extramedullary myeloid leukemia (EML)At time of imagingDefined as increased fludeoxyglucose F-18 uptake on positron emission tomography (PET)/computed tomography and increased signal on T2 weighted imaging or diffusion weighted imaging and enhancement in soft tissue on whole body PET/magnetic resonance imaging. Estimates and 95% confidence intervals for the incidence of EML will be reported for each imaging modality based on the exact Clopper-Pearson method.
