Microenvironment and Immunity of Digestive Cancers - East Paris Multicentric Cohort

Sponsor: Assistance Publique - Hôpitaux de Paris

Summary

Colorectal and pancreatobiliary cancers are the most common digestive cancers. Their incidence has particularly increased over the last few decades, leading to suspicion that environmental factors are involved. In addition, strategies for the therapeutic management of these cancers are evolving in the context of the development of immunotherapies. Tumor microenvironment is a potential source of new diagnostic, prognostic and predictive markers and new therapeutic targets. The links between tumor microenvironment and modulation of the immune system in colorectal and pancreatobiliary cancers are poorly understood. Molecular classifications have been proposed for these cancers, but their link with immunity and response to treatment remains to be explored. Objective : explore links between molecular subtypes, tumor microenvironment, host (immune system, pre-metastatic niche, intestinal microbiota, metabolism), and survival (prognostic value), response (predictive value) and tolerance (toxicities) to treatments in digestive cancers, in particular colorectal and pancreatobiliary cancers. Method: Retrospective and prospective monocentric cohort study
