Results In pancreatic cancer patients the positive rate of plasma K - ms gene mutation was 73 %, without false positivity, and higher than that in the pancreatic juice and duodenal juice, but lower than that in the fine - needle aspirates. Plasma K - ras gene mutation was not found in patients with benign pancreatic disease and healthy subjects.
