BACKGROUND Cancer antigen 125 (CA-125) is a glycoprotein biomarker that is used in women with pelvic masses such as endometriosis and maybe is useful in practice of patients suspicious to endometriosis. OBJECTIVE The aim of this study was to evaluate the association between preoperative serum CA-125 levels and clinic pathological characteristic in women with endometriosis, and find out the be...

BACKGROUND To examine the predictive value of tumor markers for evaluating tumor resectability in patients with hilar cholangiocarcinoma and to explore the prognostic effect of various preoperative factors on resectability in patients with potentially resectable tumors. Patients with potentially resectable tumors judged by radiologic examination were included. The receiver operating characteris...

Gold nanowires with of designed length on a solid substrate have been proven as an efficiently immobilized affinity support for the detection of carcinoma antigen 125 (CA 125) in this study. The presence of gold nanowires provides a well-defined three-dimensional structure, and greatly amplifies the coverage of the anti-CA 125 protein on the probe surface. Moreover, the amount of anti-CA 125 va...

We report the case of a 31-year-old woman with an androgen-producing sclerosing stromal tumor found during the eighth week of gestation in association with ascites and elevated serum androgen and cancer antigen (CA)-125 levels. The combined features of ascites, elevated serum androgen and elevated CA-125 in association with this rare type of ovarian tumor is unusual. Surgical removal of the tum...

Two hundred eighty-eight serum specimens from 144 asymptomatic menopausal women were assayed two times each for CA 125. The specimens were randomly assigned to sixteen CA 125 kits. Our purpose was to quantitate the biological variability and the assay variability that occurs at low levels of this tumor marker. All of the subjects had CA 125 values less than 35 units/ml. The total error from all...

OBJECTIVES Tumor markers and biochemical parameters were investigated in patients suffering from colon cancer and in volunteer healthy persons. DESIGN AND METHODS Biochemical analyses of erythrocyte enzymes and serum values for series of established tumor markers were conducted for 40 patients diagnosed with colon cancer, before and after chemotherapy, and 29 healthy volunteers between 2008 a...

In a study of amniotic fluid from 91 Down syndrome cases and 240 controls, we have shown that the median value of CA125 in pregnancies affected by Down syndrome on the whole reflects those observed in the maternal serum from 106 affected cases and 238 controls. The median MOM for CA125 in amniotic fluid from Down syndrome pregnancies was 1.04 and in maternal serum 1.06, neither value being sign...

OBJECTIVE To compare the effectiveness of physician assessment with a new multivariate index assay in identifying high-risk ovarian tumors. METHODS The multivariate index assay was evaluated in women scheduled for surgery for an ovarian tumor in a prospective, multi-institutional trial involving 27 primary- care and specialty sites throughout the United States. Preoperative serum was collecte...

The performance of a new enzyme immunoassay (EIA) procedure (Abbott Labs.) for cancer antigen 125 (CA 125) met or exceeded the manufacturer's claims for all analytical variables examined. Overall correlation with results obtained with a radioimmunoassay (RIA) were good. However, near the decision thresholds typically chosen to define a positive result for ovarian carcinoma, EIA results were 10 ...

Isolated torsion of the fallopian tube in postmenopausal women is rare. In this case report, we detail the case of a 53-year-old patient who presented with adenomyosis and a left hydrosalpinx with high levels of CA 125 and CA 19-9. The isolated torsion of the left hydrosalpinx was observed during the operation. The serum levels of CA 125 and CA 19-9 were reduced from 129.62 and 348 to 58.2 and ...
