The goal of this clinical research study is to learn if using a new imaging solution, 3'-Deoxy-3'-18f-Fluorothymidine, in a positron emission tomography (PET) scan can help doctors determine if your brain lesion is from the tumor returning or the effects of previous treatments.
The results of this imaging scan (called an FLT PET scan) will be compared to the results of a Magnetic Resonance Imaging scan, which you have already had or are scheduled to have outside of this study.
|Condition or disease||Intervention/treatment||Phase|
|Brain Tumor||Procedure: PET Scan Drug: 3'-Deoxy-3'-18f-Fluorothymidine||Not Applicable|
FLT PET Scan:
If you are found to be eligible to take part in this study, you will have an FLT PET scan.
An FLT PET scan uses the 3'-Deoxy-3'-18f-Fluorothymidine solution, which contains a small amount of radioactive material. The radioactive nature of the solution allows the scanner to "see" it in certain places in your body. You will receive the solution by vein through a catheter. A central venous catheter is a sterile flexible tube that will be placed into a large vein while you are under local anesthesia. Your doctor will explain this procedure to you in more detail, and you will be required to sign a separate consent form.
After the injection, you will need to rest quietly until it is time for the scan. The amount of rest time may vary, but be prepared to wait for about 60 minutes. During the scan, you will lie flat on your back on a table. After the solution is injected into a vein, the PET scanner takes pictures of the radioactive solution as it moves through the body and collects at various sites in the body. By watching how the solution travels through the body and studying where the solution collects, researchers may be able to learn where the disease is in your body. The entire procedure should last about 60-70 minutes.
You must not eat or drink anything except water for at least 6 hours before the FLT PET scan.
About 2 minutes after the FLT solution is injected, blood (about 10 teaspoons) will be drawn from the catheter. This blood will be drawn to measure how much FLT is in your body and may help the study staff understand the images better.
Length of Study:
After the FLT PET scan is complete, your active participation on this study will be over.
Follow-Up Medical Record Review:
About 30 days after the FLT PET scan, you will be contacted by phone by the study staff to check if you are having any side effects. The phone call should last about 15 minutes.
Your medical records will continue to be reviewed for up to an additional 5 years to learn how you are doing, what other treatments you may have had and how they worked, if you had any new brain problems, or if the tumor came back.
This is an investigational study. The 3'-Deoxy-3'-18f-Fluorothymidine solution is not FDA approved or commercially available. At this time, 3'-Deoxy-3'-18f-Fluorothymidine solution is only being used in research.
Up to 20 patients will take part in this study. All will be enrolled at MD Anderson.

Experimental: FLT PET Scan + 3'-Deoxy-3'-18f-Fluorothymidine
After a magnetic resonance imaging (MRI) scan of brain performed, an FLT PET scan using 3'-Deoxy-3'-18f-Fluorothymidine solution performed. After solution is injected into a vein, the PET scanner takes pictures of the radioactive solution as it moves through the body and collects at various sites in the body. The entire procedure should last about 60-70 minutes.
Procedure: PET Scan
FLT Pet Scan performed about 60 minutes after 3'-Deoxy-3'-18f-Fluorothymidine solution injected.
Other Name: Positron Emission Tomography
3'-Deoxy-3'-18f-Fluorothymidine solution injected through a central venous catheter after MRI scan. After solution injected into a vein, PET scanner takes pictures of the radioactive solution as it moves through the body and collects at various sites in the body. Entire procedure should last about 60-70 minutes.
- Performance of Fluoro-L-Thymidine Positron Emission Tomography (FLT PET) and Perfusion Magnetic Resonance Imaging (MRI) in the Diagnosis of Recurrent High-Grade Glial Tumor [ Time Frame: 1 day ]Performance (sensitivity, specificity, negative/ positive predictive values) for MR perfusion and FLT PET made using prior reported values (PEI > 20% 10 and normalized uptake >1.3 17, respectively). Particular attention placed on the location for ROI's and pathology sampling in large heterogenous lesions. Additional, exploratory analysis performed to determine post-hoc optimal cut-off values for classifying glioma vs. necrosis. Logistic regression used to fit a model using a combination of a perfusion values, spectroscopy values, diffusion values, and values from FLT PET.
