The majority of ovarian cancer patients with advanced disease at diagnosis will relapse following primary treatment, with a dismal prognosis. Monitoring the levels of serum markers in patients under follow-up may be essential for the early detection of relapse, and for distinguishing high-risk patients from those with less aggressive disease. The aim of the present study was to investigate the ...

OBJECTIVE To report rates of compliance with an ovarian cancer screening protocol using serum CA125 and transvaginal sonography (TVS), performed semiannually on an alternating schedule, among participants at average or intermediate risk for developing ovarian cancer. METHODS Two hundred ninety-two women at average or intermediate risk for developing ovarian cancer were randomly assigned to ar...

Breast cancer is the second leading cause of cancer death in women. Serum biomarkers such as cancer antigen 15-3 (CA15-3), cancer antigen 125 (CA125), and carcinoembryonic antigen (CEA) can be used as diagnostic and prognostic factors and can also provide valuable information during follow-up. However, serum protein biomarkers show limited diagnostic sensitivity and specificity in stand-alone a...

BACKGROUND An ovarian cancer marker panel including leptin, prolactin, osteopontin, insulin-like growth factor II (IGFII), macrophage migration inhibitory factor and CA125 was tested for multiplex marker measurement. Multiplex was compared to single assayed tumour markers: CA125, TPS, thymidine kinase, monototal and HE4. PATIENTS AND METHODS The serum marker levels in ovarian cancer patients ...

results: the only significant difference was the older age of the malignant group vs. benign group (p = 0.001) regarding demographic findings. as concerns the clinical symptoms, presence of abdominal discomfort in pre-diagnosis period was the only significant parameter in malignant group (p = 0.001). additionally, data analysis of patients as a total group showed that specificity (96.4%), posit...

CA125 antigen is a high molecular mass, structurally heterogeneous, mucin-type molecule expressed during embryonic development as well as in adult human tissues. This study was aimed at investigating its mucin-related property of ferning, as a general complementary way of characterization. Pregnancy-associated CA125 antigen (pCA125) was examined using light, transmission and scanning electron m...

Cancer antigen 125 (CA125) is a blood biomarker that is routinely used to monitor the progression of human epithelial ovarian cancer (EOC) and is encoded by MUC16, a member of the mucin gene family. The biological function of CA125/MUC16 and its potential role in EOC are poorly understood. Here we report the targeted disruption of the of the Muc16 gene in the mouse. To generate Muc16 knockout m...

Using a new one-step, double-determinant enzyme immunoassay, we performed quantitative measurements of a mucin-type glycoprotein antigen (CA54/61) that we recently detected in sera of ovarian carcinoma patients. When the cutoff value was set at 12 units/ml, at which a high diagnostic efficiency was demonstrated [or at 20 units/ml (mean + 3 SD of healthy females)], the positive rates of ovarian ...

OBJECTIVE To explore the predictive value of tumor markers, including cancer antigen 72-4 (CA72-4), cancer antigen 15-3 (CA15-3) and cancer antigen 125 (CA125), in single or combined detection, for the diagnosis of ovarian cancer. METHODS 120 patients diagnosed with ovarian cancer from August 2011 to March 2013 and 80 patients diagnosed with benign ovarian tumors were enrolled in this test, a...

In this paper we apply computer learning methods to diagnosing ovarian cancer using the level of the standard biomarker CA125 in conjunction with information provided by mass-spectrometry. We are working with a new data set collected over a period of 7 years. Using the level of CA125 and mass-spectrometry peaks, our algorithm gives probability predictions for the disease. To estimate classifica...
