- Primary Outcome Measures
Name Time Method <p>Main study parameters/endpoints: The main study parameters are the percent<br /><br>change in hypoxic tumour volume between baseline PET and interim PET of<br /><br>hypoxia. The primary endpoint is 3-year local recurrence-free survival (LRFS).<br /><br><br /><br>Intervention: All patients are asked to undergo one additional baseline<br /><br>18F-FAZA PET-scan (hypoxia) at baseline 18F-FDG PET-imaging (glucose<br /><br>metabolism) is already performed during clinical work-up. Both 18F-FAZA and<br /><br>18F-FDG PET-scans will be repeated in the (end of the) second week of PT,<br /><br>unless no hypoxia is witnessed at baseline, then only the 18F-FDG PET-scan is<br /><br>repeated. In a pilot setting, 10 patients are asked to further undergo<br /><br>activation PET-scanning immediately after PT in the first, second and last<br /><br>week.</p><br>
