Summary

Colorectal cancer (CRC) is the 3rd most common cancer in France. Treatment of CRC relies primarily on surgical removal of the primary tumor and chemotherapy is the current standard of care for synchronous metastatic disease. Overall survival remains strongly correlated with the tumor stage at the time of surgery, from 90% at five years for localized disease (stages 1 and 2), to around 20% for metastatic forms of the disease (stage 4). Recent research in cancer highlights the role of the immune system in the development, evolution and fate of tumors. Understanding the nature of interactions between different immune cells infiltrating the tumor is important for the development of innovative therapies. Recently, the consensus molecular classification of CRC confirmed the importance of the immune response in CRC by showing that a "high immune response" is a good prognostic indicator for patients with this pathology. However, immunotherapies are effective for only a minority of patients with metastatic CRC. Indeed, anti Programmed cell Death 1 (anti-PD-1), -PD-L1 immune checkpoint blocking antibodies have only shown effectiveness in patients with microsatellite instability (MSI), which only represents 5% of metastatic CRCs.

Thus, the aim of this study is to better understand the role of the immune system on the development of CRC and its possible modulation to treat or prevent metastatic recurrences.
