Summary

Immunotherapy have revolutionized the field of oncology, but response rates are low and all patients relapse, due to cellular and soluble immunosuppressive mechanisms. These immunosuppressive mechanisms will be better characterized and their involvement in therapeutic responses in non-small cell lung cancers (NSCLC). Indeed, large transcriptomic analysis of different subsets of immunosuppressive cells will performed, correlating them to clinical outcome in a cohort of stage III disease, treated by radiochemotherapy and immunotherapy as maintenance, and stage IV treated by immunotherapy as first-line treatment. Furthermore, we will analyse cellular mechanisms by in vitro studies, assessing the effect of immunosuppressive cells, provided by fresh tumor samples, on phenotype and functions of lung cancer cell lines. The aim of this study is to better characterize immunosuppressive landscape of NSCLC and mechanisms involved in their protumor functions.
