18F-Fluorocholine (18F-FCho) to Distinguish Necrosis From Recurrence in Brain Metastases

This study is ongoing, but not recruiting participants.
National Institutes of Health (NIH)
Information provided by (Responsible Party):
Memorial Sloan Kettering Cancer Center Identifier:
First received: January 14, 2014
Last updated: April 4, 2017
Last verified: April 2017
The main purpose of this study is to determine the distribution of 18F Fluorocholine (18F-FCH) in the brain which can help distinguishing radiation-induced scarring from tumor regrowth. In addition, the study will measure levels of 18F-FCH in the blood and (if applicable) in the brain lesion tissue that is removed as part of the planned brain surgery.

Condition Intervention
Brain Metastases Procedure: 18F-FCH PET Scan

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: 18F-Fluorocholine (18F-FCho) to Distinguish Necrosis From Recurrence in Brain Metastases

Further study details as provided by Memorial Sloan Kettering Cancer Center:

Primary Outcome Measures:
  • to distinguish radiation necrosis from progressive tumor [ Time Frame: 1 year ]
    by comparing the PET imaging results to the surgical pathology

Enrollment: 19
Actual Study Start Date: January 2014
Estimated Study Completion Date: January 2018
Estimated Primary Completion Date: January 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: pts with brain mets going for surgery
This study will enroll patients with brain metastases that are evolving after SRS who are scheduled to undergo surgical resection. Eligible patients will undergo an 18F-FCH PET study 1-to-7 days pre-operatively. Although no toxicity has been previously reported following 18F-FCH administration, patients will be contacted 1-3 days after their scan and asked whether they experienced any adverse effects. The patients who have a positive 18F-FCH PET study (in which there is visible focal "hot spots" (a focus of lesion/normal white matter ratio >1.4) of 18F-FCH) will undergo further evaluation and be administered a second administration oflower activity 18F-FCH at the time of surgery. The purpose of the second 18F-FCH administration in the operating room is to further elucidate the tissue distribution of 18F-FCH radioactivity with respect to the histopathology of the surgically resected tissue.
Procedure: 18F-FCH PET Scan
