Real-world Study of First Line Pembrolizumab- or Nivolumab-treated HPV-positive Recurrent/Metastatic Oropharyngeal Squamous Cell Carcinoma

Pembrolizumab and nivolumab (with or without chemotherapy) are used to treat head and neck cancer. The middle part of the throat (oropharynx) is a common location for head and neck cancer. This cancer is known as oropharyngeal squamous cell carcinoma (OPSCC) and is most often caused by human papillomavirus (HPV) infection. This real-world evidence study carried out in the United States (US) will assess patient demographic and clinical characteristics, treatment patterns, and effectiveness of pembrolizumab and nivolumab (with or without chemotherapy) in patients with HPV positive (HPV+) OPSCC after their cancer spread (metastatic) and/or returned (recurrent). The collected real-world data can be compared with data derived from matched study populations in clinical studies that test new therapies in patients with HPV+ OPSCC. This will allow a more reliable evaluation of the clinical benefits and better-informed design of future clinical studies in this patient population.

* Have access to baseline assessment scan within 30 days prior to initiating 1L therapy for HPV+ R/M OPSCC and response assessment confirmed by objective measurements within 26 weeks of initiation of 1L therapy.
* Must have been followed for 6 months or more since initiation of 1L therapy for R/M OPSCC.

Exclusion Criteria:

* Participation in a controlled clinical trial for 1L R/M OPSCC.
* Central nervous system involvement or other concurrent malignancy at the time of 1L initiation.
