CA 19-9 serum concentration was determined by a immunoradiometric technique in 130 subjects to evaluate its role in differentiating pancreatic cancer from chronic pancreatitis. Two threshold values were chosen, 17 and 37 U/ml. With the former, sensitivity, specificity and diagnostic accuracy were 86.7, 62.3 and 49.0 respectively, with the latter 73.3, 87.0 and 60.3%. The receiver-operating characteristic curves demonstrated a satisfactory discriminating capacity of CA 19-9 as regards pancreatic cancer and chronic pancreatitis; in contrast, the discrimination was poor for other gastrointestinal diseases, mainly of a malignant nature.

Abstract
CA 19-9 serum concentration was determined by a immunoradiometric technique in 130 subjects to evaluate its role in differentiating pancreatic cancer from chronic pancreatitis. Two threshold values were chosen, 17 and 37 U/ml. With the former, sensitivity, specificity and diagnostic accuracy were 86.7, 62.3 and 49.0 respectively, with the latter 73.3, 87.0 and 60.3%. The receiver-operating characteristic curves demonstrated a satisfactory discriminating capacity of CA 19-9 as regards pancreatic cancer and chronic pancreatitis; in contrast, the discrimination was poor for other gastrointestinal diseases, mainly of a malignant nature.File in questo prodotto:
