研究概览
简要总结
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.
详细描述
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.
