Brief Summary
Squamous cell carcinomas of the upper aero-digestive tract (SCC-UADT) represent the seventh cause of cancer and affect approximately 600,000 patients per year worldwide. The majority of UADT cancers are diagnosed at an advanced stage (70.3% at stage III and IV) and less than 60% of these patients are free of the disease at 3 years, despite aggressive multimodal local treatment by surgery and /or radiochemotherapy. The average progression-free survival (PFS) at 2 years varies between 45 and 60% depending on the studies. Tumor recurrence is most often incurable. To our knowledge, no study has demonstrated the benefit of early evaluation of the rate of decrease in ctDNA at 1 month after the end of radiotherapy alone or associated with concomitant treatment, as a predictive factor of PFS in UADT squamous cell carcinomas regardless of their HPV status. The main objective of this study is to evaluate the value of measuring the quantity of circulating tumor DNA (ctDNA) at 1 month post-treatment as a predictive factor for PFS at 24 months.

Outcome Measures
Primary Outcomes (1)
To evaluate the value of measuring the quantity of circulating tumor DNA (tcDNA) at 1 month post-treatment as a predictive factor for progression-free survival at 24 months.
ctDNA will be measured quantitatively as the number of copies of methylated ctDNA of the genes of interest per mL of plasma. The ctDNA measurement will be evaluated by the rate of decrease in ctDNA between the centering scanner sample and 1 month post-treatment. Two groups will then be considered: patients with a reduction ≥ 85% and those with a reduction \< 85%. Progression-free survival is defined by the time elapsed between the date of end of treatment (radiotherapy associated or not with concomitant treatment) and the onset of disease progression or death from all causes.
At 1 month post-treatment
Secondary Outcomes (6)
Evaluate the value of measuring the quantity of ctDNA at 1 month post-treatment as a predictive factor for overall survival and specific survival at 24 months.
At 1 month post-treatment
Study the kinetics of the evolution of ctDNA quantities during treatment and during follow-up up to 24 months.
During treatment and follow-up up to 24 months.
Evaluate the evolution of ctDNA quantities during treatment and follow-up as a predictive factor for progression-free survival and overall survival at 24 months.
At 24 months.
Evaluate the discriminatory capacity of ctDNA at 1 month post-treatment to predict response to treatment at 24 months.
At 1 month post-treatment
Compare the clinico-pathological characteristics according to the 2 defined groups: patients with a ≥ 85% decrease in ctDNA between the centration scanner sample and the sample at 1 month post-treatment and those with a decrease <85%.

Study Arms (1)
Interventional arm
OTHER12 blood samples will be taken from patients suffering from non-metastatic stage III and IV SCC-UADT (oral cavity, larynx, oropharynx, hypopharynx, maxillary sinus), naïve to any treatment
Interventions
A blood sample of 20 mL (2 tubes of 10 mL) for research purposes will be collected during: * The day of the centering scan (Visit 1); * During treatment at Week 2 and Week 6 (+/- 1 week) (Visit 2 and 3); * The day of the post-therapeutic visit scheduled between 3 and 5 weeks after the end of radiotherapy, whether or not associated with concomitant treatment (Visit 4); * At each monitoring visit following radiotherapy associated or not with concomitant treatment (every 3 months for 24 months (V5 to V12 ; V12 = final visit) * When the disease progresses before initiation of the 2nd line of treatment.
Eligibility Criteria
You may qualify if:
- OMS 0 to 2;

- Patient capable and willing to follow all study procedures in accordance with the protocol;
- Patient affiliated to the social security system.
You may not qualify if:
- Minor patient;

- Patient who has already had cancer within 5 years (cancer other than in the UADT sphere);
- OMS \> 2;
- Contraindication to radiotherapy treatment associated or not with concomitant treatment;
- Patient already included in another therapeutic trial;
- Metastatic disease (stage IVc);
- Pregnant woman, who may be pregnant, or currently breastfeeding;
- Persons deprived of liberty or under guardianship (including curatorship).
