The epitope specificities of 30 monoclonal antibodies (MAbs) against the most common human cytokeratins. i.e., Nos. 8, 18, and 19, in epithelial cells were investigated in the ISOBM TD-5 Workshop. Seven research groups from universities or companies participated independently in the evaluation of the antibody specificities. The complex assembly of(More)
In recent years, numerous serum and cell/tissue-based markers have been described for colorectal cancer (CRC). The aim of this article was to provide guidelines for the routine clinical use of some of these markers. Lack of sensitivity and specificity preclude the use of any available serum markers such as carcinoembryonic antigen (CEA), CA 19-9, CA 242, CA(More)
The aim of this article is to present updated guidelines for the use of serum, tissue and faecal markers in colorectal cancer (CRC). Lack of specificity and sensitivity preclude the use of all existing serum markers for the early detection of CRC. For patients with stage II or stage III CRC who may be candidates for either liver resection or systemic(More)
A sensitive and reproducible fully automated method for the determination of amino acids in plasma based on reversed-phase high-performance liquid chromatography and o-phthaldialdehyde pre-column derivatization is described. A 5-microns Spherisorb ODS 2 column (125 x 3 mm I.D.) was selected for routine determination. Over 40 physiological amino acids could(More)
BACKGROUND Around 4% of all couples remain involuntarily childless. These people often experience insufficient social support, which further aggravates the distress symptoms such as physical health problems, anxiety, depression and complicated grief. This study investigates the association of coping style and the degree of satisfaction regarding social(More)
Recommendations are presented for the routine clinical use of serum and tissue-based markers in the diagnosis and management of patients with breast cancer. Their low sensitivity and specificity preclude the use of serum markers such as the MUC-1 mucin glycoproteins (CA 15.3, BR 27.29) and carcinoembryonic antigen in the diagnosis of early breast cancer.(More)
BACKGROUND The array of antibodies and assay formats utilised by kit manufacturers contribute to different values being quoted as clinically "normal". Kit-specific reference range limits will maximise the clinical utility of tumour marker assays. MATERIALS AND METHODS Serum samples (approximately 800) were obtained from volunteers, age 20-70 years, in(More)
Tissue polypeptide antigen has been advocated over the past two decades as a serum tumour marker. It was a long time before it was proven that these proteins in the serum are related to cytokeratin fragments. In this study the different behaviour of the test systems TPA, TPS, TPA(cyk) and CYFRA 21.1 were investigated in serum samples, mainly of metastasized(More)

The serum levels of tissue polypeptide antigen were determined using the M3 monoclonal antibody (TPS) and compared with the serum levels of carcinoembryonic antigen (CEA) and breast carcinoma antigen 15-3 (CA 15-3) in 96 patients with benign breast tumors, in 25 breast cancer patients with no evidence of disease, in 139 preoperative breast cancer patients(More)
TPS, CA 15-3 and CEA were determined in metastatic breast cancer patients during treatment. After six months of follow-up the patients were divided into four groups according to the UICC criteria for treatment response. Forty-six patients with a more favorable prognosis (complete remission, partial remission or stable disease) were followed for an extended(More)
