  1. Medical history and physical examination within 28 days of enrolment to the study.
  2. PET-CT-scan of the neck and MRI of the neck within 6 weeks of enrolment to the study.

  3. CT-Chest or PET scan 6. Performance status: ECOG 0-2 7. Adequate renal, liver and haematological functions within 21 days of enrolment in the study.

  a. Significant cardiac event including i. Unstable angina or symptomatic cardiac insufficiency within 6 months of participation to the study.

ii. Myocardial infarct within 6 months of enrolment iii. Any cardiac past medical history that increases significantly the risk of cardiac complication according to the investigator.

b. Any past medical history of ventricular arrhythmia c. Uncontrolled hypertension (Systolic arterial pressure of ≥ 160 mmHg or diastolic pressure ≥ 95 mmHg) d. Long QT congenital syndrome e. Left ventricular ejection fraction of less than 45% measured by isotropic ventriculography for patients with a significant cardiac past medical history (myocardial infarct, severe hypertension, arrhythmia or exposition to anthracyclines).

7. Presence of any serious medical condition not allowing the patient to undergo the treatment protocol including, but not limited to:

1. Past medical history of significant neurological or psychiatric disorder (ex: uncontrolled psychotic disorder) preventing an informed consent or that would limit compliance to treatment and follow-up.
