Simple blood test could spot returning throat cancer sooner
NCT ID NCT04965792
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a blood test that looks for HPV DNA in the blood of people treated for HPV-positive oropharyngeal cancer. The goal is to see if the test can find cancer recurrence earlier than standard follow-up methods. About 150 participants are being followed after treatment to compare the blood test results with routine scans and exams.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Blood test for circulating HPV DNA
- What this could lead to
- If successful, this blood test could help catch cancer return earlier than current methods, potentially improving treatment timing and outcomes.
- What could go wrong
- This is an early-stage study with 150 participants, so results may not apply to everyone. The test might miss some recurrences or give false alarms.

Inclusion Criteria: * Participants must have histologically or cytologically confirmed incident or recurrent squamous cell carcinoma of the tonsil or base of tongue (oropharynx) - includes biopsy of any lymph node with clinical evidence of an oropharynx tumor (unknown primary carcinoma in an involved cervical neck lymph node is permitted if high-risk HPV testing is positive on the involved node) * HPV-associated tumor as defined by one or more : positive p16 immunohistochemistry (\>70%) OR in situ hybridization OR PCR-based methods * Age 18 years or older * Will undergo oropharyngeal cancer treatment with curative intent * Ability to understand and the willingness to sign a written informed consent document. * Baseline positive or detectable ctHPV DNA result in plasma OR detectable corresponding HPV DNA in tumor tissue prior to treatment Exclusion Criteria: * Distant metastatic disease (M1, AJCC 8th edition)
