FLT PET/CT w pomiarze odpowiedzi u pacjentów z wcześniej nieleczoną ostrą białaczką szpikową
Wczesna ocena odpowiedzi na leczenie w AML za pomocą obrazowania FLT PET/CT
This phase II trial studies fluorothymidine F 18 (FLT) positron emission tomography (PET)/computed tomography (CT) in measuring response in patients with previously untreated acute myeloid leukemia. FLT is a radioactive substance that may "light up" where cancer is in the body. FLT is injected into the blood and builds up in cells that are dividing, including cancer cells. Diagnostic procedures, such as PET/CT, may help measure a patient's response to earlier treatment.

Szczegółowy opis
PRIMARY OBJECTIVES:
I. To evaluate the negative predictive value (NPV) of post-treatment FLT PET/CT imaging for complete remission (CR) in patients receiving induction chemotherapy for acute myeloid leukemia (AML).
SECONDARY OBJECTIVES:
I. To evaluate the positive predictive value (PPV) of post-treatment FLT PET/CT imaging for complete remission.
II. To estimate the sensitivity and specificity of post-treatment FLT PET/CT imaging for detecting complete remission.
III. To correlate FLT PET/CT imaging with biologic correlates (minimal residual disease [MRD] assessment) IV. To correlate FLT PET/CT imaging with relapse-free survival and overall survival.
EXPLORATORY OBJECTIVES:
III. To evaluate pre-treatment FLT PET/CT imaging as a predictor of complete remission.
IV. To evaluate the change between pre-treatment and post-treatment FLT PET/CT imaging as a predictor of complete remission.
OUTLINE:
Patients receive anthracycline intravenously (IV) on days 1-3 and cytarabine IV on days 1-7 for up to 2 courses. Patients then undergo FLT PET/CT within 3 days before or after the nadir bone marrow biopsy (between days 10-17 after initiation of first induction cycle and prior to reinduction). Patients may undergo an optional FLT PET/CT prior to induction chemotherapy if it does not interfere with commencement of treatment. Patients also undergo bone marrow biopsy and aspiration and blood sample collection during screening and on the trial.
After completion of study, patients are followed up at day 28-35, and then up to 1 year beyond the end of study accrual period.

Patients then undergo FLT PET/CT within 3 days before or after the nadir bone marrow biopsy (between days 10-17 after initiation of first induction cycle and prior to reinduction). Patients may undergo an optional FLT PET/CT prior to induction chemotherapy if it does not interfere with commencement of treatment.

Negative Predictive Value of Post-treatment Fluorothymidine F 18 (FLT) Positron Emission Tomography (PET)/Computed Tomography (CT) Imaging for Complete Remission (CR) in Comparison With Blast Counts From Bone Marrow Biopsy (BMBX)
Ramy czasowe: Up to day 35
|
Three imaging parameters (standardized uptake value [SUV]mean, SUVmax, heterogeneity of FLT uptake [SUVhetero]) will be measured from an FLT PET/CT scan and SUVmax will be the primary endpoint. Higher values of SUVmax assume to indicate a non-response the therapy and a cut point of 7 (SUVmax >7) will be used as the threshold indicating a negative scan. The binomial proportion of negative predictive value (NPV) and the corresponding exact confidence intervals will be calculated. In addition, the calculated NPV will be tested against the null hypothesis to see if it's significantly larger than 0.64 (NPV of day-14 BMBX in CR prediction). CR:Complete remission CRi: Complete remission with incomplete platelet recovery LFS: Leukemia-free state Non-responders defined as Not (CR,CRi,or LFS) Negative predictive value (NPV) of the post-treatment FLT PET/CT scan is Probability ((not CR,CRi,or LFS) │ SUVmax >7 ) |

FLT PET/CT Imaging to Predict Relapse-free Survival
Ramy czasowe: Up to day 35 and up to 4 years for RFS
|
compare the Recurrence-Free Survival (RFS) between positive and negative post-treatment FLT PET/CT scans, where an SUVmax less than or equal to 7 (i.e., low FLT uptake) was considered a positive result, and an SUVmax greater than 7 (i.e., high FLT uptake) was a negative result. Participants were followed for survival outcomes until study closure when the last participant has been followed for 1 year after study enrollment. The relapse endpoint included both reappearance of blasts in the blood; and presence of more than 5% blasts not attributable to another cause Time-to-relapse was measured from the date of the remission bone marrow biopsy to the date of first recurrence or death, whichever came first. RFS was only evaluable for participants with a clinical response of CR, CRi, or LFS at the remission bone marrow biopsy. |
