Molecular imaging with positron emission tomography (PET) using [18F] fluorodeoxyglucose (FDG) has been suggested as an early, sensitive marker of tumour response to anticancer drugs by monitoring the changes in glucose metabolism in tumours. Recently, FDG-PET has shown to be highly sensitive in detecting early response in other tumours. In this study, the investigators will prospectively investigate the role of early FDG-PET (at day 7 and week 6) in outcome prediction.

Further study details as provided by Universitaire Ziekenhuizen Leuven:

Primary Outcome Measures:
  • PET response on day 7 [ Time Frame: day 7 ]

Secondary Outcome Measures:
  • To determine whether the PET criteria for response on day 7 correlates with the CT criteria of minimum 10% decrease in tumour size (RECIST) at week 6 [ Time Frame: week 6 ]
  • To define the optimal cutoff value of SUVmax and their predictive value [ Time Frame: at day 7 and week 6 ]
  • To explore the test/retest reliability of PET/CT in this setting [ Time Frame: 2 weeks ]
  • To assess the value of PET/CT at day 7 in predicting overall survival [ Time Frame: up to 1 year ]
  • To asses the correlations between biomarkers and PET changes after Cetuximab [ Time Frame: up to 6 months ]
