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...

PURPOSE The clinical relevance of CA 19-9 as surrogate biomarker in advanced pancreatic cancer is a matter of debate. EXPERIMENTAL DESIGN This retrospective multicenter study included patients with histologically confirmed advanced pancreatic cancer treated with first-line therapy. Analysis of CA 19-9 was done using the Elecsys assay (Roche Diagnostics). For an analysis of CA 19-9 kinetics, a...

The CA 19-9 assay detects a carbohydrate antigen on multiple protein carriers, some of which may be preferential carriers of the antigen in cancer. We tested the hypothesis that the measurement of the CA 19-9 antigen on individual proteins could improve performance over the standard CA 19-9 assay. We used antibody arrays to measure the levels of the CA 19-9 antigen on multiple proteins in serum...

AIMS To assess diagnostic value of Carbohydrate Antigen 19-9 (CA 19-9), combined CA 19-9 and K-ras mutation in plasma DNA in diagnosing patients with pancreatic carcinoma. MATERIALS AND METHODS MEDLINE, EMBASE, the Cochrane Library, Sinomed, CNKI and other databases, from established to November, 2013, were searched for initial studies. All the studies published in English or Chinese relating...

Serum carbohydrate antigen 19-9 (CA 19-9) has been identified as biochemical marker for biliary tract cancer (BTC). The purpose of this study was to evaluate its value as a treatment response marker and its value as a prognostic parameter in patients with unresectable BTC. We analyzed 70 patients with BTC treated with chemotherapy. CA 19-9 levels before and after two treatment courses were anal...

AIM Both of the diagnosis and treatment evaluation are time-consuming conditions in patients with pulmonary and pleural tuberculosis. The aim of this study was to establish the validity of tumor markers CA 125, CA 15-3, and CA 19-9 in the diagnosis of pulmonary and pleural TB and to verify the success of the treatment protocol. PATIENTS AND METHODS The levels of tumor markers CA 125, CA 15-3,...

PURPOSE Carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA 19-9) are the most frequently used tumor markers in the clinical setting of colorectal cancer (CRC). This study was designed to investigate the correlation between preoperative serum levels of CA 19-9 (pre-CA 19-9) and the clinicopathologic factors of patients with CRC. METHODS A study was performed on 333 patients with ...

The tumour marker CA19-9 is a sensitive marker for pancreatic, gastric and hepatobiliary malignancies. High CA 19-9 level indicates unresectable lesions and a poor prognosis. The objective of the study was to determine the significance and implications of elevated CA 19-9 levels in the serum. A one-year retrospective review of all patients who had CA19-9 measured in our Medical Centre was under...
