Brief Summary:

Hypoxia and tumor cell proliferation are important mechanisms contributing to resistance to radiotherapy in human head and neck tumor cells. Currently, assessment of these two tumor characteristics is performed in biopsies using immunohistochemical staining and subsequent analysis. A promising non-invasive method of characterizing a tumor is the use of positron-emission tomography (PET). Specific tracers can be used to detect hypoxia and proliferative activity. 18F-misonidazole is a tracer for hypoxia and 18F-thymidine is a tracer for proliferation.

Patients suffering from head and neck cancer and who will undergo surgery will be included in this study.

One week before the surgery the patients will undergo a CT-scan and a PET-scan with either of the tracers. Shortly before the surgery they will be given immunohistochemically detectable marker substances enabling the characterization of the tumor samples gathered from the resection specimen. These markers are pimonidazole for detection of hypoxia and iododeoxyuridine for detection of tumor cell proliferation.

The data collected by PET-scan will be analysed and compared to the results acquired by immunohistochemistry.

Intervention Details:
  • Procedure: 18F-FLT and 18F-MISO-PET
    18F-FLT-PET-images will be acquired one hour after injection of 250 MBq FLT. 18F-MISO-PET: 400 MBq FMISO will be injected intravenously. Marker administration: The day before surgery (≤ 24h) pimonidazole (500 mg/m2) will be administered intravenously in 100 ml saline over 20 min. IdUrd (200 mg) will be administered as bolus injection 20 min before surgery.

Primary Outcome Measures :
  1. To validate 18F-MISO-PET for detection of tumor hypoxia and 18F-FLT-PET for detection of tumor cell proliferation by immunohistochemical assessment of hypoxia and proliferation in head and neck cancer resection specimen. [ Time Frame: 1 month ]

Secondary Outcome Measures :
  1. To assess if functional information obtained by 18F-MISO-PET and 18F-FLT-PET can improve the definition of target volume for radiotherapy treatment planning. [ Time Frame: 1 month ]
