OBJECTIVE We followed up the presence of Kirsten rat sarcoma (K-ras) mutations in plasma DNA and assessed its clinical value in patients with pancreatic cancer. METHODS Plasma samples (N = 430) of 56 patients with pancreatic cancer and 13 patients with pancreatitis were analyzed by real-time polymerase chain reaction using peptide nucleic acid-mediated polymerase chain reaction clamping. RE...

conclusions non-invasive assessment of hepatic fibrosis could be done using the egy-score. egy-score could differentiate no or early fibrosis (stage f0-f2 metavir) from severe fibrosis or cirrhosis (stage f3 - f4 metavir) with 83.7% accuracy. results combined elevation of ca 19-9 and ca 125 with a summated value > 37 u/ml is predictive of severe hepatic fibrosis or cirrhosis (stage f3-f4 metavi...

OBJECTIVE Colorectal cancer (CRC) is among the most common malignancies worldwide. Understanding CRC prognosis at the initial diagnosis is very important for therapeutic strategy selection. This study was conducted to evaluate the prognostic value of preoperative serum carbohydrate antigen 19-9 (CA19-9), carcinoembryonic antigen (CEA) and carbohydrate antigen 125 (CA125) for predicting 5-year r...

BACKGROUND The serum level of carbohydrate antigen 19-9 (CA 19-9) depends on the tumor size and differentiation grade. Jaundice can cause an elevation of serum CA 19-9, although the nature of this interaction is not fully understood. PATIENTS AND METHODS This was a retrospective study of 26 patients with potentially resectable pancreatic adenocarcinoma. Serum CA 19-9 was correlated with the h...

Glycoproteins have a unique position in the pathogenesis of human diseases. Most of the commonly employed protein biomarkers are glycoproteins. Examples include CA19-9 (carbohydrate antigen 19-9) to follow-up patients with pancreatic cancer, CEA (carcinoembryonic antigen) for multiple solid tumors and CA125 (carbohydrate antigen 125) used in the diagnosis, follow-up and therapy of patients with...

The CdTe quantum dots (QDs), graphene nanocomposite (CdTe-G) and dextran-Fe3O4 magnetic nanoparticles have been synthesized for developing an ultrasensitive electrochemiluminescence (ECL) immunoassay for Carcinoembryonic antigen 19-9 (CA 19-9) in serums. Firstly, the capture probes (CA 19-9 Ab1/Fe3O4) for enriching CA 19-9 were synthesized by immobilizing the CA 19-9's first antibody (CA 19-9 A...

Synchronous serum specimens from the systemic and portal circulations of 43 patients with gastrointestinal cancer were assayed for levels of carcinoembryonic antigen, CA 19-9, and CA 125 tumor-associated antigens. The number of patients having a mean ratio of portal to systemic levels greater than 1 and the observed quantity of tumor-associated antigens were significant for carcinoembryonic ant...

We examined the prognostic value of normal levels of four serum cancer markers, carcinoembryonic antigen (CEA), carbohydrate associated antigen (CA19-9), alpha-fetoprotein (AFP) and cancer antigen 125 (CA125), in gastric cancer patients. Among 1927 gastric cancer patients enrolled in this study, 1477 were male (76.6%) and 450 were female (23.4%). The median age was 57 years (range 20-86). Clini...

with specific tumor markers .So, tumor markers Ca 15-3, Ca19-9, Ca 125, and CEA were fluctuated in normal ranges. Serum levels of alphafetoprotein (a-FP) were significantly elevated reaching the plateau of 392 iu/ ml (normal ranges: <9.5 iu/ml), supporting the sonographically evoked opinion of underlying malignancy. Except that AST (62 IU/L), ALT (73 IU/L) and LDH (309 IU/L) were mildly increased.
