Roles of circulating carcinoembryonic antigen and calcitonin in diagnosis of medullary thyroid carcinoma: a comparative study.
Carcinoembryonic antigen (CEA) and calcitonin (CT) were simultaneously determined in sera and tumor tissues from 15 patients with medullary carcinoma of the thyroid (MCT). Serum CEA was increased in all but one patient, and CT did in all of them. Both levels were significantly related to the weight of excised tumor, but not to the presence of metastasis. Furthermore, a significant correlation w...
متن کاملFive Patients with Medullary Thyroid Carcinoma Presenting as Asymptomatic Elevation of Carcinoembryonic Antigen Level.
Dear Editor, Early detection of malignancies is not easy. Few methods of health screening have been proven to be of value. The use of carcinoembryonic antigen (CEA) in health screening has never been proven to result in early detection of cancers1 but requests to test tumour markers continue to be made. A raised CEA is not an uncommon fi nding and there are no established protocols on how to ap...
متن کاملCarcinoembryonic antigen in thyroid disease.
Plasma carcinoembryonic antigen (CEA) levels were measured by the Z-Gel technique in 138 patients with benign thyroidopathies, 25 patients with thyroid cancer, and 141 normal persons. Levels were raised (above 5 ng/ml) in 2% of the normal subjects, in none of the patients with benign thyroidopathies, and in 20% of the patients with thyroid cancer. They were considerably raised in all cases of m...
متن کاملOncocytic Variant Of Medullary Thyroid Carcinoma - A Case Report
Medullary thyroid carcinoma (MTC) is a rare tumor arising from parafollicular C-cells. The oncocytic variant of MTC is an extremely rare diagnosis, with less than 20 cases reported. Here we present the case of a 36-year-old male patient with complaints of neck swelling and dysphagia. On fine needle aspiration cytology (FNAC), a Hürthle cell neoplasm was suggested. Finally with histopathol...
متن کاملAntihemophilic factor antigen. Localization in endothelial cells by immunofluorescent microscopy.
The tissue localization of antihemophilic factor (AHF, Factor VIII) has been determined by immunofluorescent studies using monospecific rabbit antibody to human AHF. Specific staining demonstrating AHF antigens has been identified in endothelial cells of a wide range of human tissues. The staining pattern was observed in endothelial cells of arteries, capillaries, and veins as well as the cells...
