  Purpose

This is a diagnostic study to look for low levels of oxygen (hypoxia) in pancreatic cancer using an imaging test called positron emission tomography (PET). Hypoxia can influence how pancreatic cancer grows and responds to treatments such as chemotherapy and radiotherapy. The use of PET scans to measure hypoxia may be better and simpler than the approaches used previously. This study will assess whether or not PET scans using a tracer called 18F-FAZA (18F-Fluoroazomycin Arabinoside) can provide useful information about hypoxia in pancreatic cancer. Also as part of the study, a blood sample will be taken to study biomarkers (substances in the body that may be important indicators of hypoxia and/or pancreatic cancer) that may be useful in studying pancreatic cancer and hypoxia.

Primary Outcome Measures:
  • Measure the hypoxia level in Patients with Pancreatic Cancer using Positron Emission Tomography (PET) with 18F-Fluoroazomycin Arabinoside (18F-FAZA). [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Correlate FAZA PET uptake in pancreatic cancer with the extension of the disease. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Standardized uptake statistics will be calculated for each volume of interest (VOI): Maximum standardized uptake value (SUVMax), mean standardized uptake value (SUVMean) and standard deviation of standardized uptake values (SUVSD).

  • Correlate FAZA PET uptake in pancreatic cancer with CA 19-9 levels. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Standardized uptake statistics will be calculated for each volume of interest (VOI): Maximum standardized uptake value (SUVMax), mean standardized uptake value (SUVMean) and standard deviation of standardized uptake values (SUVSD). These parameters will be correlated with increasing or decreasing CA 19-9 levels (U/ml).

  • Correlate FAZA PET uptake in pancreatic cancer with tumor response. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Standardized uptake statistics will be calculated for each volume of interest (VOI): Maximum standardized uptake value (SUVMax), mean standardized uptake value (SUVMean) and standard deviation of standardized uptake values (SUVSD). Tumor response is measured in millimeters. Complete response is a tumor reduction of <5 mm, partial response is at least a 30% reduction, progressive disease is a 20% increase, and stable disease is no increase in shrinkage and no increase in growth.

  • Correlate FAZA PET uptake in pancreatic cancer with patient disease-free survival (DFS). [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Kaplan-Meier actuarial method and/or the Cox proportional hazard model will be utilized.

  • Compare the pattern of FAZA uptake in different tumor sites (eg., lymph node metastases and liver metastasis). [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Standardized uptake statistics will be calculated for each volume of interest (VOI): Maximum standardized uptake value (SUVMax), mean standardized uptake value (SUVMean) and standard deviation of standardized uptake values (SUVSD).

  • Determine the feasibility of using dynamic and static PET imaging of FAZA uptake in patients with pancreatic cancer. [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Pancreatic cancer

Detailed Description:

This is a single centre, single arm hypoxia study of pancreatic cancer with PET FAZA imaging.

PET-CT imaging of tumor hypoxia with FAZA will be done prior to the start of standard treatment for pancreatic cancer with chemotherapy. The FAZA PET-CT imaging session will last approximately 2.5 hours and include an initial dynamic scan to completely characterize the initial rapid phase of FAZA uptake, followed by a later static scan.
