Study Overview
Brief Summary
The goal of this project is to characterise the heterogeneity of all cell populations (tumour cells, stromal and immune microenvironment) present in the tumor and their normal (and leucoplasic) counterparts by scRNAseq in OSCC patients.
Detailed Description
Epidermoid carcinomas of upper aerodigestive tract are the 8th most common cancers in the world. Worldwide, this represents more than 500.000 cases per year and 20.000 cases per year in France (statistics 2018-2020). Among these cancers, oral squamous cell carcinoma (OSCC) are the most common location, leading to significant morbidity and mortality.
OSCC treatment is based on surgery and/or radiotherapy and/or chemotherapy. Immune Check point Inhibitors (ICIs) targeting PD-1 have been approved for recurrent and metastasic OSCC. However, only 15-20% of these patients are treated thanks to this anti-PD-1. Thus, there is a real need to improve the efficacy of ICIs in the treatment of HNSCC. The scRNAseq is a method which allows to study the tumoral heterogeneity, the microenvironment and the dynamic and regulation mecanisms in cells cancer. This technology could improve patient stratification, identify pronostic biomarkers, constitute an important tool in the therapeutical take care and lead to understand tumoral evolution and develop new prevention strategies.
The aim of the study is to characterise the heterogeneity of all cell populations (tumour cells, stromal and immune microenvironment) present in the tumor and their normal (and leucoplasic) counterparts by scRNAseq in OSCC patients.
