The tumour associated CA-125 antigen is widely used in monitoring ovarian carcinoma. In women with a massive pleural effusion and ascites, markedly increased CA-125 levels may lead to an erroneous diagnosis of ovarian cancer. Very high levels of tumour markers may be present in patients with benign pleural effusion, ascites, and chronic liver disease. Raised levels of tumour markers in serum or...

Abstract Background Inadequacy of effective sensitive and specific screening modalities results in late-stage diagnosis ovarian cancer. Cancer Antigen-125 (CA-125) individually possesses limited specificity for differentiating adnexal masses. The present study aimed to evaluate the Human Epididymis Protein 4 (HE4), Risk Ovarian Malignancy Algorithm (ROMA), Index (RMI) ameliorating sensitivity b...

BACKGROUND Little is known about the correlations between tumor markers (TMs), breast cancer subtypes, site(s) of metastasis and prognosis. METHODS Women diagnosed with metastatic breast cancer were included. Breast cancer subtypes were defined as LuminalA, LuminalB, LuminalHer2, Her2, Basal and non-Basal triple negative (TN). Levels of elevation of TM values [cancer antigen 15-3 (CA 15-3), c...

DNA methylation plays an important role in carcinogenesis and cancer development. In this study, we examined gene methylation in epithelial ovarian cancer (EOC) using cationic conjugated polymer (CCP)-based fluorescence resonance energy transfer (FRET) to evaluate the application of cumulative methylation alternations of genes associated with cancer antigen 125 for early cancer diagnosis. The m...
