| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| To compare the diagnostic value of uPAR-PET/CT with the current imaging options (CT, MRI and ultrasound). The reference that will be used as  "gold standard" is the pathological examination of the surgically removed tissues. 
 |  | 
| E.2.2 | Secondary objectives of the trial |  | 
| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria | 
| • Able to understand patient information and to give informed consent • Not previously irradiated or operated on neck
 
 OSCC or OPSCC referred to primary surgical treatment
 |  | 
| E.4 | Principal exclusion criteria | 
| • Pregnancy • Patients who are candidates for curative intentional radiation
 • Patients who have had surgery or radiation therapy to the neck as this may alter the lymph drainage.
 • Other diseases assessed by the investigator as basis for exclusion.
 • Age under 18 or over 85 years
 • Obesity> 140 kg
 |  | 
| E.5 End points | 
| E.5.1 | Primary end point(s) | 
| 1. The number of lymph node metastases that can be identified by means of uPAR PET / CT compared with the histological findings.
 |  | 
| E.5.1.1 | Timepoint(s) of evaluation of this end point | 
| The primary end point will be evaluated from the PET/scan and compared with the histological findings postoperatively. |  | 
| E.5.2 | Secondary end point(s) | 
| 1. Evaluation of the correlation between uPAR PET signal (quantified as SUVmax) and the immunohistochemical expression of uPAR evaluated by an H-score (intensity x the percentage of stained tumor tissues throughout the tumor margin). 
 2. Evaluation of the correlation between tumor burden (assessed by TNM staging) uPAR-PET signal (assessed as SUVmax) and the amount of uPAR metabolites in plasma.
 
 3. Determination of the lower detection limit of the amount of tumor tissue for uPAR-PET correlated with the histological H-score x tumor size (where tumor size is evaluated on the pathological preparation of pathologist)
 |  | 
| E.5.2.1 | Timepoint(s) of evaluation of this end point | 
| The secondary end points will be evaluated from the PET/scan and compared with the histological findings and blood sample postoperatively. |  |
