blood sampling: The intervention consist in blood samples (18mL) collected 1 and 3-months after the end of chemoradiotherapy
The goal of this ancillary clinical trial is to evaluated circulating DNA as a biomarker of residual disease after chemoradiotherapy for locally advanced head and neck squamous cell carninoma.
The main question it aims to answer is :
\- Does circulating DNA (cDNA) be able to detect residual disease 3 months after the end of chemoradiotherapy ? Researchers will compare detection of cDNA at 3-months and objective response (clinical and radiological).
Participants will :
* be included in the main study (Neck-TAR)
* have a blood sample 1 and 3-month after the end of treatment
