ABSTRACT
Pancreatic cancer is a kind of high degree of malignant gastrointestinal tumor,and its incidence has increased significantly in recent years.Due to the low early diagnosis rate,and the extreme low middile or late resection rate of pancreatic cancer,Pancreatic cancer's prognosis is poor.Therefore,improving the early diagnostic rate of pancreatic cancer has very important significance for improving the prognosis.Early diagnosis of pancreatic cancer is dependent on tumor markers detection to a great extent.And proteomics progress rapidly in recent years and has been widely applied in clinical research.It provides an effective way to find markers.Among all of the spec imens,secrum is easy to obtain,and it allows repetitive detection.What is more,secmm is also renewable.So it is the most ideal for biological specimens.In this review,the proteomics technology role in pancreatic cancer patients serum detection were summarized.
