Abstract
In 116 subjects [human], serum RNase and ferritin were determined in order to evaluate whether their combined evaluation might improve the diagnostic accuracy of each test. Significantly higher levels were found in pancreatic cancer patients both for RNase and ferritin than in control subjects and chronic pancreatitis. Sensitivity and specificity in diagnosing pancreatic cancer were 86% and 46%, respectively, for RNase; 76% and 65% for ferritin. One of the 2 tests was pathological in 100% of pancreatic cancer, with a specificity of 29.9%; both were pathological in 62.1%, with a specificity of 82.1%. The results emphasize the limits of the combined assessment of pancreatic cancer markers.
