Use of [F-18] FLT for Imaging With Positron Emission Tomography (PET)

Summary

RATIONALE: Diagnostic procedures, such as 3'-deoxy-3'-\[18F\] fluorothymidine (FLT) PET imaging, may help find and diagnose cancer. It may also help doctors predict a patient's response to treatment and help plan the best treatment. PURPOSE: This phase I trial is studying FLT PET imaging in patients with cancer.

Detailed description

OBJECTIVES: Primary * Evaluate the use of 3'-deoxy-3'-\[18F\] fluorothymidine (FLT) positron emission tomography (PET) imaging to measure tumor proliferation and the DNA synthetic pathway (thymidine kinase levels) in patients with cancer. Secondary * Determine the efficacy of FLT PET imaging in detecting lesions and estimating response to treatment. OUTLINE: Patients undergo up to four 3'-deoxy-3'-\[18F\] fluorothymidine positron emission tomography imaging procedures.

Arms & interventions

• Device3'-deoxy-3'-[18F]fluorothymidine

  The tracer compound \[F-18\] FLT will be injected into the patient's veins in a small volume of normal saline solution. The PET scan data collection is started immediately and is continued for 2 hours. This procedure will measure tumor growth within the body. Blood may be withdrawn (through the catheters) up to a total volume of 30 milliliters (or 2 tablespoons) for each scan. A urine sample may be collected at the end of the imaging of the tracer compound to analyze its breakdown products.
