5. Study Description

Brief Summary
Recent studies estimated that 15 to 20% of all cancers in humans are associated with viruses. Among oral cancer about 90% are oral squamous cell carcinomas (OSCC). Alcohol and tobacco consumption have been recognized for years as the main risk factors for development of OSCCs. However, 10 to 20% of patients suffering from OSCCs are non-smokers and/ or non-drinkers. Consequently, the hypothesis of another agent responsible has risen. Indeed, several studies have suggested the possibility that a virus could be associated with or be a causal agent of OSCC. The first objective is to detect and characterize the presence of infectious agent (mostly virus) transcripts in pre-malignant or malignant tumours from patients with OSCCs.The secondary objectives are (i) to associate and (ii) if possible define a causality link between these agents and a subset of potentially malignant disorders and/or OSCCs.

contralateral healthy tissue biopsy
Intervention Description
At the time of surgery, a part of the specimen, plus a biopsy of the healthy (control) contralateral mucosa (i.e. right border of the tongue for a SCC of the left border, left cheek for a dysplasia of the right cheek and so on) will be harvested for research and immediately frozen at -80°C first in dry ice, then in a -80°C freezer.
