title: [Urine diacetylspermine as a novel tumor marker for pancreatobiliary carcinomas].
abstract: A novel urine tumor marker, diacetylspermine, was compared with two conventional serum tumor markers, carcinoembryonic antigen (CEA) (highly specific for pancreatic cancer) and carbohydrate antigen (CA) 19-9 (highly sensitive for pancreatic cancer), in 125 patients with bilio-pancreatic tumors. When the diagnoses of benign or malignant conditions were examined, the sensitivity of urine diacetylspermine (75%) was shown to be higher than that of CEA (44%; P = 0.044) and CA19-9 (75%). The specificity of urine diacetylspermine (81%) was lower than that of CEA (92%) and as high as that of CA19-9 (80%). These results suggest that urine discetylspermine is a highly sensitive and specific novel marker for bilio-pancreatic carcinoma.
