Bead-based ELISA for validation of ovarian cancer early detection markers.
PURPOSE Efforts to validate ovarian cancer early detection biomarkers with immunoassays are challenged by the limited specimen volumes available. We sought to develop a specimen-efficient assay to measure CA125 in serum, assess its reproducibility, validity, and performance, and test its potential for multiplexing and combining with human epididymis protein 4 (HE4), a promising novel ovarian ca...
متن کاملSerum protein markers for early detection of ovarian cancer.
Early diagnosis of epithelial ovarian cancer (EOC) would significantly decrease the morbidity and mortality from this disease but is difficult in the absence of physical symptoms. Here, we report a blood test, based on the simultaneous quantization of four analytes (leptin, prolactin, osteopontin, and insulin-like growth factor-II), that can discriminate between disease-free and EOC patients, i...
متن کاملDiagnostic markers for early detection of ovarian cancer.
PURPOSE Early detection would significantly decrease the mortality rate of ovarian cancer. In this study, we characterize and validate the combination of six serum biomarkers that discriminate between disease-free and ovarian cancer patients with high efficiency. EXPERIMENTAL DESIGN We analyzed 362 healthy controls and 156 newly diagnosed ovarian cancer patients. Concentrations of leptin, pro...
متن کاملTumor markers for early detection of ovarian cancer.
The overall mortality rate for ovarian cancer is 75%, but when diagnosed at stage I, 90% of patients can be cured. Strategies for early detection require high sensitivity (>75%) and extremely high specificity (99.6%) to attain a positive predictive value of at least 10%. When functioning alone, conventional markers fall short of this required sensitivity or specificity. Greater specificity can ...
متن کاملValidation of Candidate Serum Ovarian Cancer Biomarkers for Early Detection
OBJECTIVE We have previously analyzed protein profiles using Surface Enhanced Laser Desorption and Ionization Time-Of-Flight Mass Spectroscopy (SELDI-TOF-MS) [Kozak et al. 2003, Proc. Natl. Acad. Sci. U.S.A. 100:12343-8] and identified 3 differentially expressed serum proteins for the diagnosis of ovarian cancer (OC) [Kozak et al. 2005, Proteomics, 5:4589-96], namely, apolipoprotein A-I (apoA-I...
