The purpose of this study is to better understand the natural history of oropharyngeal carcinoma (OPC), with or without an association with the human papilloma virus (HPV). For this study, the investigators plan to collect blood from OPC patients prior to treatment and at six subsequent time points.
Participants with known or suspected oropharyngeal carcinoma. All patients with OPC getting surgery at Stanford are invited to participate in the study.

Exclusion Criteria:
Sample collection
30-50cc of blood
Time frame: prior to start of treatment
Sample collection
30-50cc of blood
Time frame: up to 36 months post-op
tumor sample

Time frame: Day 1
Started Jul 2023 (actual). Primary completion is estimated for Aug 2027, 49 months after the start.
Of 47 observational studies under Oropharyngeal Neoplasms, half reached primary completion within 110 months of starting (the median), counting those still running; a quarter within 40. This study's planned 49 months is below that.
