Research progress of tumor biomarkers of protein in early diagnosis of pancreatic cancer

Pancreatic cancer is one of the deadliest cancers of the digestive tract with an obviously increasing incidence around the word in recent years. It is diffcults to diagnosis in the early stage because of the deficience of specific symptoms. Radical resection is the most effective method to treat pancreatic cancer , but those patient often lose radical surgery opportunity when be diagnosised at advanced stages. Their prognosis is poor. Early diagnosis can greatly improve the rates of radical resection and promote the prognosis of the disease, and reliable tumor markers can be used for early screening and early diagnosis for pancreatic cancer. In recent years, the rapidly development of proteomics and its technology makes tumor markers become a popular research fields in pancreatic cancer.
