The objective of this trial is to study the efficacy of treatment of human papilloma virus (HPV) related oropharyngeal cancer with chemotherapy followed by Transoral Robotic Surgery (TORS) as definitive treatment. Current treatment of oropharyngeal cancer are chemo-radiotherapy. There is significant lifelong side effects associated with this approach related to tissue effects of radiotherapy. The side effects results in significant quality of life deterioration among the patients. Overall there is 20% failure rate with this treatment approach. The study hypothesis is that treatment with upfront (neoadjuvant) chemotherapy followed by transoral surgery and neck dissection is highly effective treatment allowing competitive cure rate compared to chemo-radiotherapy with less than 10% failure rate, while avoiding radiotherapy in majority of cases. It is also hypothesized that better functional and quality of life outcome maybe achieved with this approach.

The current standard of care for advanced (AJCC-7 edition stage III and IV) oropharyngeal squamous cell carcinoma are concomitant chemoradiation, or surgery followed by adjuvant radiation therapy with or without concomitant chemotherapy. These approaches have persistent and significant lifelong side effects and sequelae related to treatment, and in particular related to radiotherapy. The side effects of radiotherapy (augmented with concomitant chemotherapy) include soft tissue fibrosis, loss of salivary function, dry mouth, life long disturbed taste function, poor dental health with rapidly decaying teeth, dysfunction of swallowing, significant loss of the mobility of the base of tongue and pharyngeal constrictors, loss of laryngeal elevation, esophageal stricture, and at times severe side effects such as soft tissue necrosis or osteoradionecrosis of the mandible. About 10% of the patients undergoing chemoradiation for oropharyngeal cancer develop long term swallowing dysfunction with feeding tube dependency. As a result , patient's quality of life (QOL) is adversely affected. Improvements in the side effect profile of treatment, the functional outcome, and the QOL remain very important areas of advancement in treating this patient population. Improvements in functional outcome need to be achieved while maintaining or improving the oncologic outcome and cure rates for cancer, compared to the standard of care.

Use of Taxane based chemotherapy along with Platinum drugs (Cisplatin and Carboplatin) in high dose neoadjuvant setting, coupled with Transoral Laser Microsurgery (TLM) or Transoral Robotic Assisted Surgery (TORS), allows potential for improved oncologic outcome as well as avoidance of long term sequelae of high dose radiation therapy to head and neck. These transoral surgical approaches (TLM and TORS) provide improved functional outcome compared with traditional open composite resections and complex reconstructive algorithms for oropharynx. TLM and TORS are currently in clinical use for early (stage T1 and T2 with N0 or N+ve) oropharyngeal cancer.

De-escalation treatment strategies of TORS followed by adjuvant radiotherapy are being investigated currently. However even without de-escalation there is overall 18-20% rate of treatment failure and half of failures are due to distant metastasis in the absence of loco-regional recurrence. In this study the investigators propose systemic escalation of treatment with neoadjuvant chemotherapy (docetaxel and cisplatin) followed by de-escalated locoregional treatment with transoral surgery and neck dissection reserving radiotherapy for salvage.

This approach has the potential for improved functional outcome by avoiding short and more importantly long term and permanent sequelae of radiation therapy in oropharyngeal cancer treatment. This approach is a new paradigm in treatment of oropharyngeal cancer, and can significantly improve the functional outcome of cancer treatment.

Phase II Study: Induction Chemotherapy Followed by Transoral Robotic Surgery and Neck Dissection for Definitive Management of Oropharyngeal Squamous Cell Carcinoma. (NECTORS Trial)

Subjects will be evaluated for cancer recurrence or persistence. Index cancer recurrence or persistence following completion of treatment at any site will be recorded as an event. Progression free survival will be calculated at 2 years according to the Kaplan Meier methods.

The trial subjects will be followed for vital statistics (dead or alive) from the time enrolled in the trial. Any deaths that is caused by the index cancer will count as an event. DSS will be calculated with intention to treat analysis according to the Kaplan Meier methods at 5 years.

The trial subjects will be followed for vital statistics (dead or alive) from the time of enrolment. Death from any cause will be counted as an event. Overall survival will be calculated according to the Kaplan Meier methods at years.

Patient-reported general quality of life outcome will be measured according to The European Organization for Research and Treatment of Cancer (EORTC) general quality of life questionnaire (EORTC QLQ-C30) at 3 month, 6 months, and 12 months following the completion of treatment. These questionnaires are validated and an integrated system for assessing the quality of life (QoL) of cancer patients participating in clinical trials. Outcome score for functional scales at 12 months will be compared to pretreatment levels.

Patient-reported quality of life outcome will be measured according to EORTC head and neck specific questionnaire (QLQ-H\&N35) prior to trial treatment (baseline), at 3 month, 6 months, and 12 months following the completion of treatment. These questionnaires are validated and an integrated system for assessing the quality of life (QoL) of head and neck cancer patients participating in clinical trials. Outcomes for symptom scales in H\&N-35 at 12 months will be compared to pretreatment levels.

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.

In the multicenter study of CIRCOS, Circulating biomarkers in oropharyngeal cancer, patients with oropharyngeal cancer or cancer of unknown primary of the head and neck are consecutively included. Plasma samples are collected at diagnosis, at the end of treatment and during surveillance after treatment.

At diagnose participants will fill in informed consent and a form regarding known risk factors for cancer. Tissue from the tumor will be analyzed for HPV genotype with a multiplex q-PCR. Information about p16 will be collected from medical records.

ctHPV-DNA are short DNA fragments that leaks into the blood stream from tumor cells during apoptosis and necrosis. In the study, ctHPV-DNA will be extracted from blood plasma. Levels of ctHPV-DNA (copies/mL) will be measured using digital droplet PCR (ddPCR) with genotype specific assays (based on the result of q-PCR at diagnose) used in singleplex (SAGA diagnostics). A negative sample after treatment will be defined as a good molecular response for evaluation after treatment. Two consecutive, positive samples during surveillance will be defined as molecular recurrence. If a molecular recurrence is seen patients will be contacted and offered an extra clinical control at an Ear nose and throat department.

If a patient is HPV negative in tissue, the tissue will be analyzed with whole genome sequencing. If a mutation is found, a personalized ddPCR-kit will be used for plasma.

All patients will be followed for five years.

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

Correlation of ctHPV-DNA and radiologic tumor burden at diagnosis and post treatment. ctHPV-DNA will be evaluated by ddPCR (copies/mL) at diagnose and at the end of treatment. The levels of ctHPV-DNA will be used as a measure of molecular tumor burden. The molecular tumor burden will be compared with the radiologic tumor burden, measured in diameter and volume in the diagnostic and evaluation computed tomography. The correlation will be calculated using Kendall rank correlation coefficient

The kinetics in ctHPV-DNA and will be compared to radiological confirmed treatment response in order to test ctHPV-DNA as a biomarker for treatment response. Radiological response will be evaluated according to the RECIST-criteria. Kinetics of ctHPV-DNA will be described as percentage change between pre- and post-treatment levels of ctHPV-DNA.
