Brief Summary

In squamous cell carcinoma of the tongue, complete surgical resection of the tumor generally represents the primary treatment strategy. Among factors determining the disease prognostic, the surgical margins status is essential for the continued management of the patient, with or without complementary therapies. Generally, surgical margins are defined using visual and tactile elements. Unfortunately, in 15 to 30 percent of cases, they are defined as positive after histopathological examination, on average 5 to 7 days post-surgery. Techniques have recently been developed to analyze the cancerous and non-cancerous nature of tissues, using the spectral properties of tumor cells. SpiderMass™ is an instrument equipped with a probe for tissue micro-sampling and real-time molecular profile analysis. It is thus ultimately a tool for anatomopathological decision support, for diagnosis and prognosis of the disease. Used in the operating room, SpiderMass™ could also become an innovative surgical tool to precisely define cancerous areas in situ and the margins status in intraoperative conditions. Based on the principle of artificial intelligence, the SpiderMass™ machine must initially learn to recognize pathological tissues versus healthy. This project aims to accomplish this first phase of machine learning for squamous cell carcinoma of the tongue.

RECRUITING

Biospecimen

Retention: SAMPLES WITHOUT DNA

Tissue samples will be taken from the tumor and the non-tumor areas. Surgical specimens will be taken in a fresh state immediately after surgery, by an anatomopathologist and a pathological anatomy technician. The sample will be analyzed under standard conditions. Two sites will be selected macroscopically (including a tumor area, a dysplasia area, and a non-tumor area).
