RATIONALE: Diagnostic procedures, such as positron emission tomography (PET) using [18F]-labeled substance P antagonist receptor quantifier, may be effective in finding disease in patients with pancreatic cancer.

PURPOSE: This phase I trial is studying how well a PET scan using [18F]-labeled substance P antagonist receptor quantifier works in finding disease in patients with pancreatic cancer.

Primary Outcome Measures:
  • Proportion of tumors detected by [18F]-labeled substance P antagonist receptor quantifier positron emission tomography

Estimated Enrollment: 33
Study Start Date: September 2007
Study Completion Date: December 2008
Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
Detailed Description:


  • Determine whether [18F]-labeled substance P antagonist receptor quantifier positron emission tomography can identify pancreatic cancer evident on multiphase CT scan.

OUTLINE: Patients undergo multiphase CT scan of the chest, abdomen, and pelvis. No more than 15 days later, patients receive [18F]-labeled substance P antagonist receptor quantifier IV and undergo positron emission tomography over 6 hours.

Blood is collected periodically to measure the metabolism of the radiotracer by high performance liquid chromatography with radioactive detectors.
