Detecting HPV-positive pelvic cancer relapses using blood tests

Circulating Tumor DNA for the Early Detection of HPV-positive Pelvic Cancer Relapses

Not applicable Interventional Institut Curie · NCT03739775

This study is testing if blood tests can help find out if patients treated for HPV-related pelvic cancer have a relapse during their follow-up visits.

What this trial studies

This study focuses on patients who have been treated for HPV-induced stage II or III invasive pelvic cancer and are currently in post-treatment follow-up. Participants will undergo blood sampling to detect circulating tumor DNA (ctDNA) at each hospital visit over a period of 30 months. Clinical, biological, and radiological data will be collected to monitor for any signs of cancer relapse. If a relapse occurs, follow-up will be discontinued, while those without relapse will continue to be monitored for an additional 6 months.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have been curatively treated for HPV-induced pelvic cancer and have no evidence of invasive tumors.

Not a fit: Patients with active invasive tumors or those unable to participate in regular follow-up will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enable earlier detection of cancer relapses, potentially improving patient outcomes.

How similar studies have performed: Other studies have shown promise in using ctDNA for cancer detection, indicating that this approach may be effective.
