Acute Myeloid Leukemia Clinical Trial
FLT PET/CT in Measuring Response in Patients With Previously Untreated Acute Myeloid Leukemia
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.
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).
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 FLT PET/CT at complete remission detection.
III. To evaluate pre-treatment FLT PET/CT activity as a predictor of complete remission.
IV. To evaluate the change between pre-treatment and post-treatment FLT PET/CT activity as a predictor of complete remission.
V. To correlate post-treatment FLT PET/CT imaging parameters with day 28 bone marrow aspirate/biopsy and minimal residual disease assessment by flow cytometry.
VI. To correlate FLT PET/CT imaging parameters (maximum FLT uptake across the total bone marrow compartment [SUVmax], mean FLT uptake across the total bone marrow compartment [SUVmean], heterogeneity) with biologic correlates (minimal residual disease [MRD] assessment).
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.
After completion of study, patients are followed up at day 28-35.
Patients must have previously untreated AML and be candidates for intensive induction chemotherapy; patients are allowed to have had prior hydroxyurea
Patients must not have acute promyelocytic leukemia (APL) and must not have evidence of t(15;17)(q22;q21)
Patients must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0-3 (restricted to ECOG performance status [PS] 0-2 if age > 70 years)
Patients must have left ventricular ejection fraction (LVEF) > 45% or within institutional normal limits
Patients must be able to lie still for a 1.5 hour PET scan
Patient must NOT have a history of allergic reaction attributable to compounds of similar chemical or biologic composition to 18F-fluorothymidine
Patient must NOT weigh more than the maximum weight limit for the PET/CT table for the scanner(s) to be used at each center
The patient is participating in the trial at an institution which has agreed to perform the imaging research studies, completed the ECOG-American College of Radiology Imaging Network (ACRIN) defined scanner qualification procedures and received ECOG-ACRIN approval as outlined
Women must not be pregnant or breast-feeding; all females of childbearing potential must have a blood test or urine study within 2 weeks prior to registration to rule out pregnancy; a female of childbearing potential is any woman, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months)
