Multi-modality Imaging and Collection of Biospecimen Samples in Understanding Bone Marrow Changes in Patients With Acute Myeloid Leukemia Undergoing TBI and Chemotherapy

Multi-Modality Imaging and Correlative Studies in Patients With Leukemia

This clinical trial investigates multi-modality imaging and collection of biospecimen samples in understanding bone marrow changes in patients with acute myeloid leukemia undergoing total body irradiation (TBI) and chemotherapy. Using multi-modality imaging and collecting biospecimen samples may help doctors know more about how TBI and chemotherapy can change the bone marrow.

OUTLINE: Patients are assigned to 1 of 2 cohorts.

COHORT I (TLMI+FLT/TMLI): Patients may undergo optional fluorothymidine F-18 PET scan over 2 hours at baseline, on days 30 and 100, at 1 year, and at time of relapse. Patients undergo DECT and water-fat MRI scan over 30 minutes at baseline, on days 30 and 100, at year 1, and at time of relapse. Patients also undergo collection of bone marrow and blood samples at baseline, on days 30 and 100, and at 1 year. Patients undergo fluorothymidine F-18 PET, DECT, and water-fat MRI as in TMLI+FLT.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change over time in cellularity and adiposity	A non-parametric smoothing plot will be produced in the first step to view changes in the trend. Measurements will be summarized by mean +/- standard deviation (SD) at each time point. Exploratory within subjects' correlation will be examined using Pearson correlation between adjacent time points. A random-effects model will also be used to investigate whether there is significant time trend. Will use a two-sample t-test for comparing bone marrow cellularity percentage at pre-HCT and 1-year post-HCT between the total marrow and lymphoid irradiation (TMLI) group and total body irradiation (TBI) group (all cohorts). A paired t-test will also be carried out to examine if there is significant difference in changes of cellularity between these two groups.	Up to 1 year post-hematopoietic stem cell transplant (HCT)
Change over time of red marrow (cellularity) and yellow marrow (adipocyte)	A non-parametric smoothing plot will be produced in the first step to view changes in the trend. Measurements will be summarized by mean +/- SD at each time point. Exploratory within subjects' correlation will be examined using Pearson correlation between adjacent time points. A random-effects model will also be used to investigate whether there is significant time trend. In addition, bone marrow/peripheral blood measurements will be correlated with survival outcome (relapse).	Up to 2 years
Number of hematopoietic stem cell (HSC) colony forming units (sub-analysis)	Will be assessed by HSCs from marrow aspirate.	Up to 2 years
Ratio of HSC sub-populations (sub-analysis)	Long-term, short-term, multi-potent progenitor, common myeloid progenitor, and granulocyte macrophage progenitor will all be assessed by HSCs marrow aspirate.	Up to 2 years
Hematopoietic stem cell density in bone marrow biopsy samples (sub-analysis)	Will be assessed by CD34 staining.	Up to 2 years
Microvascular density in bone marrow biopsy samples (sub-analysis)	Will be assessed by CD31 staining.	Up to 2 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Standardized uptake value (SUV) distribution at different skeletal sites	Changes in standardized uptake value (SUV) from fluorothymidine F-18 (FLT) positron emission tomography (PET) imaging uptake will be described. The distribution or heterogeneity will be first estimated using medians, ranges, interquartile ranges, means and standard deviations. Kolmogorov-Smirnov test (K-S) test will be performed to examine whether the distribution is the same for different skeletal sites. Also as a side product, sensitivity and specificity of the imaging will be estimated.	Baseline
SUV distribution and presence of focal hot spot	Changes in SUV from FLT-PET imaging uptake will be described. The distribution or heterogeneity will be first estimated using medians, ranges, interquartile ranges, means and standard deviations. K-S test will be performed to examine whether the distribution is the same for different skeletal sites. Also as a side product, sensitivity and specificity of the imaging will be estimated.	Baseline
Change in FLT PET activity		Baseline up to 2 years
SUVmax at site of biopsy	SUVmax: the maximum SUV within the region of interest. SUVmin: the minimum SUV within the region of interest. SUVmean: the average SUV within the region of interest. As a primary goal we will be using SUVmax. Other parameters are secondary parameters. Sites: site of bone marrow biopsy is iliac crest. Image analysis is done at the different locations - iliac crest, Lumber spine, and femur.	At time of biopsy
SUVmean at site of biopsy	SUVmax: the maximum SUV within the region of interest. SUVmin: the minimum SUV within the region of interest. SUVmean: the average SUV within the region of interest. As a primary goal we will be using SUVmax. Other parameters are secondary parameters. Sites: site of bone marrow biopsy is iliac crest. Image analysis is done at the different locations - iliac crest, Lumber spine, and femur.	At time of biopsy
Blast counts	Will be assessed by bone marrow aspirate smears.	Up to 2 years
SUVmax at iliac crest, lumber spine, and femur	For each location SUV measurement, software provides SUVmax, SUVmin and SUVmean. These are not separate measurements. Once region (volume) is defined, software will calculate SUV in the form of SUVmax, SUVmean and SUVmin. For simplicity, we will report SUVmax only as primary parameter. SUVmean and SUVmin will be secondary SUV parameters.	Up to 2 years
SUVmean at iliac crest, lumber spine, and femur	For each location SUV measurement, software provides SUVmax, SUVmin and SUVmean. These are not separate measurements. Once region (volume) is defined, software will calculate SUV in the form of SUVmax, SUVmean and SUVmin. For simplicity, we will report SUVmax only as primary parameter.
