Finding HPV DNA in the blood of people with anal or cervical cancer.

Official title: Circulating HPV DNA in Cancers of the Anus and Uterine Cervix Treated With Definitive Radiation Therapy

Run by University of Chicago · NCT04857528 · Data updated 2026-11-12

This study will test whether a blood test can find HPV DNA in people with HPV-related anal or cervical cancer before, during, and after radiation treatment.

Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) with p16-positive stage I–III anal cancer or stage I–IVA cervical cancer who are planned for definitive radiation therapy, with or without concurrent systemic therapy.

Probably not a fit

Patients whose tumors are not p16-positive, who have HPV types outside the targeted genotypes (not 16, 18, 31, 33, or 35), or who are receiving only adjuvant/postoperative radiation are unlikely to benefit from participation.

What this trial studies

This observational study enrolls adults with p16-positive anal or cervical cancer who are planned for definitive radiation, with or without chemotherapy. Blood samples will be collected before, during, and after radiation and analyzed with HPV genotyping to detect circulating HPV DNA. Archival tumor tissue and additional blood specimens will be stored for future laboratory testing to explore tumor biology and treatment response. Participation lasts about two years and involves multiple site visits for blood draws and clinical data collection.

Why it matters

Potential benefit: If successful, a simple blood test could help track HPV-related tumors and provide an earlier, less invasive signal of how patients are responding to radiation.

How similar studies have gone: Previous studies detecting circulating HPV DNA in HPV-related cancers have shown promising signals for monitoring disease, but routine clinical adoption remains limited.
