摘      要：Despite potentially curative surgery pancreatic cancer has a dismal prognosis.Serum cancer antigen 19-9(CA 19-9) correlates with tumor burden,resectability and survival in patients with pancreatic ductal adenocarcinoma.Identification of novel biomarkers may facilitate early diagnosis of pancreatic cancer and improve survival.Pancreatic juice is a rich source of cancer-specific proteins rendering it a promising tool for identifying biomarkers.Recent proteomic and micro RNA expression analyses have identified several biomarkers of potential diagnostic and prognostic value.Tumor markers CA 19-9 and carcinoembryonic antigen(CEA) are widely used in the characterization of premalignant and malignant lesions of the pancreas.Elevated level of CEA in bile is a marker for malignancy and a predictor of hepatic recurrence.The potential value of CA 19-9,CEA and lactate dehydrogenase as prognostic biomarkers in pancreatic juice and bile is unknown.Specimens of pancreatic juice and bile can be readily collected during surgical resection of the tumor.Profiling of pancreatic juice and bile to identify novel prognostic biomarkers may improve selection of patients for adjuvant therapy with a favorable impact on overall survival in patients diagnosed with pancreatic cancer.
