Primary Outcome Measures
NameTimeMethod
<p>To validate ctDNA after treatment as a predictor for the presence of residual<br /><br>disease and for the early detection of tumour recurrence.</p><br>
Secondary Outcome Measures
NameTimeMethod
<p>1. The prognostic value of ctDNA during treatment as a biomarker for treatment<br /><br>response.<br /><br>2. Timing and accuracy of ctDNA as a predictor for recurrence in comparison to<br /><br>conventional imaging.<br /><br>3. The correlation of traceable mutations found in blood / saliva in comparison<br /><br>to mutations found in tissue biopsies, as a parameter for tumor heterogeneity.<br /><br>4. The tumours* genomic status and epigenetic evolution over time under<br /><br>pressure of radiotherapy.<br /><br>5. Sensitivity and specificity of ctDNA in blood compared to saliva.<br /><br>6. The correlation between ctDNA before treatment and other clinical/biological<br /><br>parameters in the prediction of disease recurrence.</p><br>
