Pancreatic cancer is thought to be immune‐quiescent, as a variety of immune‐suppressive mechanisms can inhibit antitumor immunity.18 Low expression of major histocompatibility complex (MHC) class I molecules on pancreatic cancer cells inhibits T‐cell activation.19 CD8+ T cells are activated by interaction with antigen presented by MHC class I molecules on antigen‐presenting cells. The gene discussed is CD8A; the disease is pancreatic neoplasm.
