| 1 | Immunotherapy in pancreatic cancer:Unleash its potential through novel combinations显示文摘Pancreatic cancer is the third leading cause of cancer mortality in both men and women in the United States,with poor response to current standard of care,short progression-free and overall survival.Immunotherapies that target cytotoxic T lymphocyte antigen-4,programmed cell death protein-1,and programmed death-ligand 1 checkpoints have shown remarkable activities in several cancers such as melanoma,renal cell carcinoma,and nonsmall cell lung cancer due to high numbers of somatic mutations,combined with cytotoxic T-cell responses.However,single checkpoint blockade was ineffective in pancreatic cancer,highlighting the challenges including the poor antigenicity,a dense desmoplastic stroma,and a largely immunosuppressive microenvironment.In this review,we will summarize available clinical results and ongoing efforts of combining immune checkpoint therapies with other treatment modalities such as chemotherapy,radiotherapy,and targeted therapy.These combination therapies hold promise in unleashing the potential of immunotherapy in pancreatic cancer to achieve better and more durable clinical responses by enhancing cytotoxic T-cell responses. | Songchuan Guo Merly Contratto George Miller Lawrence Leichman Jennifer Wu | 2017 | World Journal of Clinical Oncology2017，8，3： | 3 |
