Image-Guided Stereotactic Biopsy of High Grade Gliomas

The purpose of this study is to evaluate high and low areas of growth, or proliferation, within the tumor. An imaging technique using a very small amount of a radioactive tracer called 18Ffluoro-deoxy-L-thymidine (18F-FLT) can detect areas of rapid growth within the tumor. This imaging technique is called a FLT PET imaging. This present study involves obtaining one scan using FLT PET imaging. The goal of this study is to investigate associations between the imaging findings showing differences in growth rate within the tumor and the biology of the tumor that is measured in the sampled tumor tissue. This information may be used in future brain tumor patients to determine the best combination of treatment for individual patients. These studies may also improve our understanding of the types of changes taking place in brain tumor tissue that could improve individual patient outcome. FLT is produced for human use by the MSKCC cyclotron facility under an investigational new drug (IND) approval issued by the US Food and Drug Administration (FDA). This means that FLT is produced under strict rules and regulations, is considered safe, and has been approved for use in humans for certain disease conditions. 18F-FLT has been used in several research studies to date at this institution.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Age > or = to 18 years old.
  • Radiographic appearance of a lesion presumed to be high-grade glioma.
  • Planned surgical resection.

Exclusion criteria

  • All patients who have been previously treated with radiation, chemotherapy, or other targeted drugs (patients only) for their brain tumor.

  • Patients with other active malignancies or prior treatment for non-CNS malignancies.

Treatment and study plan

18F-FLT PET Scan

Drug

The patient will undergo MRI and 18F-FLT PET scans of the brain. A IV catheter will be placed in a superficial hand or arm vein for administration of 18F-FLT (approximately 370 MBq), prepared by the MSKCC Radiochemistry Core Facility. A second venous catheter will be placed in the opposite hand or arm for venous blood sampling. If a central venous catheter is present, it will be used for blood sampling or radiopharmaceutical administration, and only a single venous catheter will be placed. Sequential blood samples may be obtained following 18F-FLT infusion for assaying whole blood and plasma radioactivity. All catheters will be removed at the end of the day.

Other names: As part of the standard surgical care for brain cancer, the patient will undergo, biopsy of the tumor. A few small tissue samples will be collected from different, sites within the tumor and used for examining the biology of the tumor tissue., Associations will be made between the 18F-FLT imaging findings at these biopsy, sites, which reflect differences in tumor growth rate, and the corresponding, biology of the tumor measured in the sampled tumor tissue.
