Brief Summary:
The results of previous studies suggest further development of [18F]EF5 as a PET tracer for imaging hypoxia. This is a non-randomized prospective study to obtain information on reproducibility of [18F]EF5 intratumor distribution using repeated pretreatment PET/CT scans.

Condition or disease Intervention/treatment Phase
Squamous Cell Carcinoma of the Head and Neck Drug: 18F-EF5 Procedure: Pretreatment PET/CT-scan (performed two times) Phase 2

Detailed Description:

All patients will undergo normal diagnostic and staging procedures, including a conventional 18F-FDG PET/CT scan for the purpose of RT or surgical planning. In addition to that, an 18F-EF5 PET/CT scan will be performed on a separate day. The patients receive intravenous injection of 250-350 MBq of [18F]EF5. After that, a venous blood sample will be obtained for measurement of plasma radioactivity. A low-dose CT (helical) will be performed for attenuation correction and anatomical reference. After that, a PET scan will be performed (starting at 3 h after injection). The second 18F-EF5 scan will be performed in a similar way 4-7 days after the first scan. A representative histologic sample of primary tumor is pre-condition for study and an effort is made to store part of fresh histologic material in liquid nitrogen for later use in immunohistochemical analysis.

Patients are scheduled to undergo preoperative or definitive chemoradiotherapy using current clinical standards after completion of the current protocol. Follow-up information (event-free survival and overall survival) will be gathered.

Arm Intervention/treatment
Experimental: Patients with stage III-IV head and neck cancer
18F-EF5 PET/CT scan
Drug: 18F-EF5
Other Name: PET/CT static imaging

Procedure: Pretreatment PET/CT-scan (performed two times)



Primary Outcome Measures :
  1. Change From Baseline in 18F-EF5 Standardized Uptake Values (SUV) [ Time Frame: Baseline and 7 days (ie time between the two scans) ]
    Standardized Uptake Values (SUV) are determined in the acquisition images of the [18F]EF5 studies.The difference between the baseline and second SUV is calculated and Bland-Altman plots are generated to compare the group means
