Very high concentrations of CA 125 have been found in some ovarian cancer patients after repeated radioimmunodetection with anti-CA 125 antibodies [OC125-F(ab')2]. In one patient we measured a CA 125 concentration of 135,000 kilo-arb. units/L, using an enzyme immunoassay involving OC125 antibodies. With an immunoradiometric assay involving use of two new anti-CA 125 antibodies (B43.13 and B27.1...

CA-125 is a 220-kD cell surface glycoprotein present in over 80% of non-mucinous epithelial ovarian carcinomas and it occurs in the serum of healthy males and females at low concentrations (< 35 U/mL). Serum CA-125 concentration may also be moderately elevated in several benign conditions, such as pelvic inflammatory disease, uterine fibroids, pregnancy, spontaneous abortion with chromosomal ab...

Various authors (1,2) have tried to ascertain whether CA 125 concentrations in PF samples were significantly higher in patients with endometriosis than in control subjects. So far, these studies have not shown any significant difference in CA 125 values obtained from undiluted PF samples. In our study, using diluted samples in one-step assay, we found that CA 125 concentrations differed between...

BACKGROUND The aim of this study was to assess the prognostic value of cancer antigen (CA) 125 and CA 72-4 in patients with ovarian borderline tumor (BOT). METHODS All women diagnosed and treated for BOT at our institution between 1981 and 2008 were included into this retrospective study (n=101). Preoperatively collected serum samples were analyzed for CA 125 (Architect, Abbott and Elecsys, R...

of death from gynaecological cancer among women in Western countries. Epithelial ovarian cancer is responsible for 85-90% of all primary ovarian tumours. Because of the asymptomatic nature of the disease, ovarian cancer is usually not detected in the early stages and therefore many women present with advanced disease and systemic metastases. Approximately 70-80% of patients present with late st...

CLINICAL CHEMISTRY, Vol. 37, No. 11, 1991 2019 riod was also checked for CA-125 concentration, and only one (of >500) had an increased CA-125 concentration (60 arb. units/mL). The CA-125 concentrations of all other sera were always <35 arb. units/mL. The ovary or the uterus, the most likely source of CA-125 in adult women, shows little functional activity in prepuberal girls. Although this does...

AIMS To investigate the incidence of ordering tests for tumor markers which are used in cancer diagnosis, follow-up treatment and detection of recurrence, the rate of elevation in benign diseases and which clinics order them frequently. MATERIALS AND METHOD Data for the tumor markers carbohydrate antigen 19-9 (CA 19-9), carcinoembryonic antigen (CEA), cancer antigen 125 (CA 125), cancer antig...

To the editor: The recent publication on ‘HE4, CA-125, and cystic ovarian mass’ is very interesting [1]. Partheen et al. [1] concluded that HE4 did not outperform CA-125. Indeed, the use of two biomarkers might be expected for increased screening ability; however, the problem of the cost should be kept in mind. Incremental analysis on additional cost should be done. Based on the present report,...

Serum carbohydrate antigen 125 (CA-125) is a marker of ovarian cancer and obesity that is related with an increased risk of ovarian cancer. Obesity is a key factor of metabolic syndrome. We evaluated the relationship between CA-125 concentration and metabolic syndrome. The data from subjects who had any cancer and chronic infection were excluded. The data of 12,196 healthy Korean women were ana...
