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.
