Molecular analysis of pancreatic juice: a helpful tool to differentiate benign and malignant pancreatic tumors?
Teich N, Mossner J
Dig Dis. 2004;22(3):235.
Chronic pancreatitis is an important predisposing condition leading to pancreatic carcinoma. As the differential diagnosis between these diseases may be difficult in 1 patient, the detection of specific tumor markers in pancreatic juice is an attractive diagnostic tool. Many studies have investigated tumor-mediated molecular alterations of the pancreatic juice, as k-ras mutations, telomerase reactivation, or promoter methylation of the tumor-suppressor genes p16INK4a and p14ARF. In this overview, we summarize these studies and conclude that molecular analysis of pancreatic juice is not useful for everyday care today. The high specificity of molecular alterations in pancreatic cancer in some pilot studies is waiting to be reproduced in large prospective trials, and has the potential to be a strong complementary marker of malignancy in patients with a pancreatic mass of uncertain dignity.
