This is due to high recurrent rate after surgical resection and poor response to chemotherapy and radiotherapy.\n\nRecent studies revealed that peri-tumoral structure and patients' immune status including cytotoxic immunity played significant role in the bad behavior of pancreatic cancer. While past studies focused on oncogenes and tumor suppressor genes, recent studies focused on patients' own immunity. Patients' immunity modified by cancer cells is found to be correlated to cancer progression and metastasis.\n\nNatural killer cells, playing an important role in cytotoxic immune system, are revealed to be decreased in patients with lung cancer, ovarian cancer, prostate cancer, colorectal cancer, and breast cancer. And in melanoma mouse model, when NK cell was suppressed, cancer progression and metastasis were accelerated.\n\nThis study sought to find the correlation of patients' cytotoxic immune status to cancer progression and status by measurement of NK cell activity in pancreatic cancer patients. This would be basic support to construct a prognostic model of pancreatic cancer for early metastasis and post operational recurrence.",[56],"Pancreatic Cancer","COMPLETED","2019-01-14",{"date":60,"type":50},"2019-01-16",{"date":62,"type":50},"2016-08-08",{"date":64,"type":50},"2017-12-20",{"name":5,"class":6},1]
