Tumor markers carbohydrate antigens CA 19-9 and CA-50 and carcinoembryonic antigen in pancreatic cancer and benign diseases of the pancreatobiliary tract.
Sera from patients with diseases in the pancreas, gallbladder, and bile duct were analyzed for the tumor markers CA 19-9, CA-50, and carcinoembryonic antigen. In particular CA 19-9 and CA-50 appear to be valuable in differentiating malignant from benign disease in these organs. Our sample of 72 patients with pancreatic cancer also indicates that CA 19-9 and CA-50 complement each other in 21% of...

متن کاملRheumatoid factor interference in the determination of carbohydrate antigen 19-9 (CA 19-9).
BACKGROUND Investigation of a 61-year-old Caucasian male suffering from fatigue and weight loss led to the finding of a carbohydrate antigen 19-9 (CA 19-9) concentration of 80 kU/L using an ADVIA Centaur analyser. Determination of CA 19-9 on Vidas, AxSYM and Architect i2000 systems gave normal results. His rheumatoid factor concentration was very high (900 kIU/L) and assay interference was susp...
متن کاملIncreased CA 19-9 level in patients without malignant disease.
BACKGROUND The measurement of carbohydrate antigen 19-9 (CA 19-9) is recommended for the diagnosis and follow-up of pancreatic cancer. However, increased CA 19-9 has also been reported in patients with various benign diseases of the lung. We aimed to elucidate the pulmonary radiographic abnormalities and laboratory results associated with increased concentrations of CA 19-9. METHODS This stud...
متن کاملPulmonary sequestration presenting with left upper abdominal bloating and marked elevation of serum carbohydrate antigen 19-9: A case report
Carbohydrate antigen 19-9 (CA19-9) is widely accepted as a tumor marker for cancers of the biliary, pancreatic and gastrointestinal tracts. Occasionally, CA19-9 is markedly elevated in the serum of patients with benign diseases. Pulmonary sequestration is a rare malformation that is characterized by the presence of lung tissue with abnormal or absent communication with the bronchi, to which blo...
