Urinary level of CA19-9 as a tumor marker in urothelial carcinoma of the bladder.
PURPOSE To diagnose the urothelial carcinoma of the bladder by measuring CA19-9 level in the urine. MATERIALS AND METHODS This study was conducted on 47 patients with histopathologically confirmed urothelial cancer and 50 control subjects. The urinary level of CA19-9 was measured in both groups by enzyme-linked immunosorbent assay after concentration of urine with Bio-Gel dry beads. Urine cyt...

OBJECTIVE To compare sera levels of CEA and CA19-9 and tissular expression of the CA19-9 and to correlate these with morphological features of the colorectal carcinoma. METHODS Forty five patients with colorectal carcinoma underwent surgical treatment following measurement of pre-operative levels of CA19-9 and CEA. Sera levels of CEA = 5.0ng/ml and CA19-9 = 37UI were deemed high values. Evalu...
متن کاملImmunohistological marker molecules
Immunohistology as well as a wide range of other biomolecular techniques depend on the use of labeled antibodies. Labelings such as radiolabels, fluorophores or enzymes may be used as reporters in distinct assay formats. Immunohistology in its proper meaning will depend on procedures which enable the identification and characterization of cellular structure and function in situ. Hence, the resp...
متن کاملSerum CA19-9 as a marker of circulating tumor cells in first reflux blood of colorectal cancer patients
Circulating tumor cells (CTCs) are used for metastasis surveillance in cancer patients, but low detection rates limit their use in colorectal cancer (CRC). We investigated the distribution of CTCs in peripheral and portal blood of CRC patients, and analyzed the relationship between serum tumor CEA/CA19-9 markers and CTCs blood levels. CTC levels detected in first reflux/portal vein blood were h...
متن کاملExpression of the carbohydrate tumor marker Sialyl Lewis a (Ca19-9) in squamous cell carcinoma of the larynx.
BACKGROUND The clinical relevance of the carbohydrate antigen Sialyl Lewis a (SLea) as a serum tumor marker in diagnosis and follow-up treatment is unquestioned in a broad spectra of human carcinomas. Overexpression of this antigen is combined with poor prognosis and malignant relapse. The aim of our study was the systematic investigation of SLea expression in squamous cell carcinoma of the lar...
