HPV-associated Oropharyngeal Carcinoma (HPV-OPC) (HPV-OPC)

17 juli 2026 uppdaterad av: Masaryk Memorial Cancer Institute

Validation of a New Method for Monitoring HPV Infection in Patients With Head and Neck Cancers

This study focuses on the longitudinal monitoring of HPV infection in patients with head and neck cancers, particularly oropharyngeal carcinoma (OPC), using a new electrochemical detection method. This method has already been successfully developed and validated for cervical cancer. The aim of the project is to monitor the dynamics of HPV viral load before the start of treatment and during conservative radiation therapy or concurrent chemoradiation therapy. HPV will be analyzed from oral swabs, oral cavity washings, and plasma as part of a small prospective study. The results of the new method will be correlated with standard techniques, particularly qPCR. Longitudinal monitoring may contribute to the individualization and potential de-escalation of treatment in selected patients.

Studieöversikt

Detaljerad beskrivning

Patients with HPV-positive head and neck tumors, primarily OPC, who are indicated for conservative radiation therapy or concurrent chemoradiation therapy will be enrolled in the study. At defined time points (before the start of treatment and during treatment), oral swabs, oral cavity washings, and peripheral blood samples will be collected, from which plasma will be isolated for analysis of viral ctDNA. We estimate approximately 20 patients with OPC indicated for radiotherapy alone or concurrent chemoradiotherapy who are p16-positive. Negative controls will be patients with OPC indicated for radiotherapy alone or concurrent chemoradiotherapy who are p16-negative (approximately 10-15).

Beskrivning

Inclusion Criteria:

Intervention / Behandling
Experimentell: p16 positive OPC patients
20 patients with OPC who were indicated for standard radiation therapy or concomitant chemoradiation therapy and who were p16-positive.
Monitoring changes in HPV DNA levels during therapy can predict the clinical response to treatment and, in the future, may allow for the safe de-escalation of the intensity of radiation therapy or chemoradiation in selected patients. We will also determine the appropriate method for collecting DNA samples so that, in the future, sampling can be as minimally invasive as possible while maintaining the necessary sensitivity and specificity. By comparing the dynamics of local mucosal samples with those of blood samples, we can observe how these dynamics differ in the event of a local or systemic relapse.
