Neuron-specific enolase in medullary thyroid carcinoma.
CLINICALCHEMISTRY, Vol. 34, No. 11, 1988 2375 trile, and applied the extract to a SepPak C18 cartridge (Waters Associates, Milford, MA) that had been washed sequentially with acetomtrile and water. To remove 24,25dihydroxy vitamin D, we washed the cartridge with water, then with methanol:water (7:3 by vol). 250HD was eluted with acetonitrile; the eluate was evaporated under nitrogen and the dri...
متن کاملRoles 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 کاملPostoperative calcitonin study in medullary thyroid carcinoma.
Calcitonin (CT) is a sensitive marker for medullary thyroid carcinoma. Normalization of early postoperative CT level is a favorable prognostic factor. The aim of this study was to establish the prognostic value of CT-level kinetics by preoperative tumor stage and postoperative elimination rate. Blood serum from 22 medullary thyroid carcinoma (MTC) patients without remote metastases was assayed....
متن کاملCarcinoembryonic antigen, squamous cell carcinoma antigen, CYFRA 21-1, and neuron-specific enolase in squamous cell lung cancer patients.
BACKGROUND Carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC-Ag), and CYFRA 21-1 are the most useful markers for non-small cell lung cancer (NSCLC), but neuron-specific enolase (NSE) is a tumor maker of choice for SCLC. The determination of NSE in NSCLC could allow selection of patients with neuroendocrine features. NSCLC patients whose tumors have neuroendocrine properties m...
متن کاملCalcitonin receptor expression in medullary thyroid carcinoma
BACKGROUND Calcitonin expression is a well-established marker for medullary thyroid carcinoma (MTC); yet the role of calcitonin receptor (CTR), its seven-transmembrane G-protein coupled receptor, remains to be established in C-cells derived thyroid tumors. The aim of this work was to investigate CTR expression in MTC and to correlate such expression with clinicopathological features in order to...
