Core Tip

Core tip: The poor prognosis of pancreatic cancer appeals for a novel strategy to treat this disease. Immunotherapies such as whole cell vaccines are currently being investigated in patients with pancreatic cancer. The recent breakthrough in cancer immunotherapy with immune checkpoint inhibitors has allowed us to reverse T cell anergy and enhance antitumour immunity. Tumour-targeted Oncolytic viruses in combination with checkpoint inhibitors function synergistically to increase the tumour antigen load, relieve immune suppression in the tumour bed while enhancing the activation of the adaptive immune system. Viro-immune-checkpoint therapy should thus be considered as a novel strategy to treat pancreatic cancer.
