Increased serum CA 19-9 levels in patients with nonmalignant diseases have been investigated in previous reports. This study evaluates the clinical significance of serum CA 19-9 elevation in pulmonary nontuberculous mycobacterial disease and pulmonary tuberculosis. The median CA 19-9 level was higher in patients with pulmonary nontuberculous mycobacterial disease than in patients with pulmonary...
BACKGROUND Tumour markers are substances produced by the tumour itself, or by the host in response to a tumour. These markers could be measured either in the blood or in body secretions. One of the most common tumour markers used in gastrointestinal diseases is Ca 19-9. It is the marker most used for pancreatic cancer, but can be elevated in many benign processes. Thus, it is not a specific mar...
Background/Aims To determine the prognostic value of carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 19-9 in gallbladder cancer (GBC) during palliative chemotherapy. Methods One hundred and twenty-three patients with pathologically confirmed unresectable GBC were included. Differences in serum CEA and CA 19-9 levels before and after chemotherapy were measured. Receiver operating ...
HYPOTHESIS Accurate differentiation between inflammatory and neoplastic tumors of the pancreas remains a diagnostic dilemma for surgeons. The aim of the study was to assess the utility of 2 neoplastic markers, cancer antigen (CA) 19-9 and CA 125, in the differential diagnosis of pancreatic tumors. DESIGN The patients were assigned to a malignant or benign group based on cytological and histol...
Simple cysts (SCs) of the liver are not associated with the biliary malformations in intrahepatic bile duct biliary. Seen in 0.1% to 7% of adult population, biliary malformations are more common in women. The levels of glycoprotein-like tumor markers (carbohydrate antigen (CA) 19-9) in the cysts and serum could be high. Although studies regarding CA 19-9 exist, sufficient data on cancer antigen...
INTRODUCTION The objective of the study was to identify the predictive factors for malignancy in pancreatic head mass as a primary outcome and assess the value of CA 19-9 as a diagnostic tool for malignancy as a secondary outcome. METHODS A prospective study of patients presented with pancreatic head mass was conducted in a tertiary care referral hospital, Manipal, India from May 2006 to Nove...
Elevated carbohydrate antigen (CA) 19-9 can indicate malignancies of the gastrointestinal, pancreatic, and biliary tracts, and be found in a pulmonary sequestration. A 30-year-old man visited Seoul National University Bundang Hospital due to elevated CA 19-9 levels, representing pulmonary sequestration of the bilateral lower lobes, which were connected with each other. We performed left lower l...
The monoclonal antibody CA 19-9 reacts with a carbohydrate epitope (sialylated lacto-W-fucopentaose II), which was shown to be part of a ganglioside extracted from a colon carcinoma cell line as well as of a mucin isolated from gastrointestinal tract tumor patients' sera. Recently, when we compared CA 19-9 levels in pancreatic juices and corresponding serum samples from a large group of patient...
The monoclonal antibody CA 19-9 reacts with a carbohydrate epitope (sialylated lacto-N-fucopentaose II), which was shown to be part of a ganglioside extracted from a colon carcinoma cell line as well as of a mucin isolated from gastrointestinal tract tumor patients' sera. Recently, when we compared CA 19-9 levels in pancreatic juices and corresponding serum samples from a large group of patient...
