Brief Summary
The goal of this observational longitudinal study is to learn about circulating tumor Human Papilloma Virus-DNA (ctHPV-DNA) as a biomarker for HPV positive oropharyngeal cancer and cancer of unknown primary of the head and neck. The main questions it aims to answer are:
- Can ctHPV-DNA be used for treatment evaluation in HPV positive oropharyngeal cancer and cancer of unknown primary of the head and neck?
- Can circulating HPV-DNA be used as a biomarker for recurrent disease during surveillance? Participants will be asked to leave plasma samples at diagnose, at the end of treatment and at every clinical follow-up. The patients are there own controls.

Outcome Measures
Primary Outcomes (1)
The accuracy of ctHPV-DNA as a biomarker for recurrent disease, measured in PPV and NPV
ctHPV-DNA will be evaluated by ddPCR. Two consecutive positive values will be defined as a molecular recurrance. The accuracy of the test will be presented with negative predictive value (NPV) and positive predictive value (PPV) at one, two (interim analysis) and at five year follow-up
5 year follow-up
Secondary Outcomes (2)
The correlation between molecular tumor burden (copies/mL) and radiological tumor burden (diameter and volume) using Kendall rank correlation coefficient.
3 months follow-up
A comparison between molecular (copies/mL) and radiological response to treatment according to RECIST (Response Evaluation Criteria in Solid Tumors) using Kruskal wallis test.
3 months follow-up
Eligibility Criteria
Study participants are recruited from multidisciplinary conferences of head and neck cancer at Örebro University hospital - Region Örebro County, Västmanland's hospital - Region Västmanland and Karolinska University hospital - Region Stockholm. Örebro University hospital is a tertiary referral hospital of three regions in central Sweden (Region Värmland, Region Sörmland and Region Dalarna) and therefore patients from these regions will also be included in this study. All patients with OPSCC at any of the study centers will be asked to participate in CIRCOS. All study participants will sign an informed written consent upon inclusion

You may not qualify if:
