About
A prospective observational study to determine the prognostic value of the timing of 50% reduction in metabolic activity (T50) during CCRT for NSCLC for treatment outcome (PFS).
Full description
This is a single-centre observational study. Patients with proven locally advanced NSCLC will be treated with concurrent chemoradiotherapy according to the standard clinical protocol of the NKI-AVL. During treatment, the biological behaviour of the tumour will be monitored with serial quantitative FDG (fluorodeoxyglucose) PET/CT scans. From these images, the time during treatment where a 50% reduction in FDG uptake relative to day 1 is reached (T50) will be derived. The T50 of progression-free surviving patients will be compared with that of relapsed or deceased patients, in order to find a value that predicts early treatment failure. An additional FDG PET/CT scan at the same day as regular follow up CT scan will be made, two months after treatment, to have a baseline after treatment for follow up.
