The immune contexture that characterizes the density, the location, the organization and the functional orientation of tumor-infiltrating immune cells in cancers has a clinical impact on patient's outcome. It is, in great part, shaped by the malignant cells, as in a given cancer type, tumors presenting different oncogenic processes have different immune contextures. Moreover, the immune contexture in metastatic sites reflects that of the corresponding primary tumors. Finally, the components forming the immune contexture represent targets and markers of efficient anti-cancer immunotherapies.
