Spots Global Cancer Trial Database for Assessment of the Cytotoxic Immune Status of Pancreatic Cancer Patients and the Severity of the Cancer Using Measurement of Natural Killer Cell Activities

Study Description

Brief Summary: Pancreatic cancer is the 5th leading cause of cancer death and the worst prognostic cancer in the world. This is due to high recurrent rate after surgical resection and poor response to chemotherapy and radiotherapy. Recent 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. Natural 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. This 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.
