Although the incidence rate of pancreatic cancer is not as high as that of other gastrointestinal carcinoma in China, the cancer mortalities of males and females ranked the sixth and seventh respectively in 2013, with a surprising low 5-year survival rate (<5%). Only 15%-20% patients are suitable for surgeries among those first diagnosed with pancreatic cancer and the 5-year survival rate of patients with R0 resection is still less than 20%.
