Tobacco and Alcohol Influence on Oncogenic Drivers and Somatic Evolution in the Oral Mucosa

Sponsor: Hospices Civils de Lyon

Summary

Head and neck cancers represent more than 500,000 cases per year worldwide, and often involve post-treatment relapse. The oral cavity is the most frequent site, but early disease stages are still insufficiently characterised and poorly detected. The study's aim is to better understand the oral mucosa somatic evolution, and how it can give rise to oral squamous cell carcinoma (OSCC). This is a multi-centric, descriptive, non-interventional cohort in healthy adult subjects. The aim of the study is to detect the presence of OSCC driver gene mutations in healthy subjects' oral mucosa, quantify whether they provide cells with a selective advantage, and study the impact of tobacco and alcohol consumption on the mutational load. This study will not allow to identify potential malignant cells, and will be usable for diagnostic purposes.
