Résumé
Checkpoint blockade immunotherapy is a therapeutic revolution in cancer treatment. However, only 5% of patients with metastatic colorectal cancer benefit from these therapies, and these tumors genetically harbored microsatellite instability status. In contrast, tumors with stable microsatellites are considered resistant to immunotherapy, and standard treatment with chemotherapies is standard of care, with few chances of curative intent. In a recent clinical trial, we demonstrated that the combination of two chemotherapies with two immunotherapies promotes the recruitment and activation of the adaptive immune system at the tumor level, resulting in clinical benefit in a significant number of patients. In parallel, a biological study revealed biomarkers of response, including CTLA-4 expression and induction of a tumor-specific immune response.
