Brief summary
uPAR PET/CT for Staging Advanced and Localised oral and oropharyngeal cancer
Detailed description
To compare the diagnostic value of uPAR-PET/CT for prognostication compared to the current imaging options (CT, MRI and ultrasound) by observer-blinded readings. The reference that will be used as gold standard is the pathological examination of the surgically removed tissues. The new imaging modality (uPAR-PET/CT) will be used in two separate groups of patients with head and neck cancer: Study I: Patients with oral cancer without clinical evidence of spread (OSCC in stage cN0) Study II: Patients with metastatic oral cancer (OSCC in stage cN +) and patients with metastatic oropharyngeal cancer (OPSCC in stage cN +).
Interventions
One injection of 68Ga-NOTA-AE105 (app. 200 Mbq) followed by Positron Emission Tomography Scan.

Eligibility
Inclusion criteria
* Able to understand patient information and to give informed consent * Not previously irradiated or operated on neck * Operable disease Study I OSCC cN0 verified histologically by pathologic examination of biopsy Study II OSCC or OPSCC N + verified histologically by pathologic examination of biopsy
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 * Allergy to 68Ga-NOTA-AE105
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The number of lymph node metastases that can be identified by means of uPAR PET / CT compared with the histological findings. | Through study completion, an average of 1.5 year |
Secondary
| Measure | Time frame |
|---|---|
| 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). | Through study completion, an average of 1.5 year |
| Evaluation of the correlation between tumor burden (assessed v.h.a. TNM staging) uPAR-PET signal (assessed as SUVmax) and the amount of uPAR metabolites in plasma. | Through study completion, an average of 1.5 year |
| 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) | Through study completion, an average of 1.5 year |
