Abstract
A high density of intratumoral effector memory CD8+/Th1 T cells is associated with favorable prognosis in most cancers and may be induced or increased by immunotherapy. Efficient adaptive immune reactions are shaped in tumor adjacent tertiary lymphoid structures, which exhibit all characteristics of immunity generating lymphoid formations in reactive lymph nodes. Malignant tumor cells impact favorably or deleteriously their immune microenvironment if they bear genetic mutations that result in neo-antigens or by producing chemokines and cytokines that recruit lymphocytes and myeloid cells or increase inflammation and neo-angiogenesis. This intricate network of interactions results in control or escape of tumors, and its understanding will help define goals to monitor efficiency of immunotherapies.
