Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This clinical trial evaluates the clinical outcome of mucosal sparing adjuvant radiotherapy after surgical exploration in HPV+ head and neck cancer of unknown primaries. The purpose of this research is to assess if radiation treatment to the neck only for tumors with unclear original locations after careful surgical evaluation will lead to historical rates of disease control while reducing side effects and toxicity from treatment.
