Serum cytokeratins determination in differentiated thyroid carcinoma

To assess the potential value of cytokeratins (CK) 8,18,19 as tumor markers for thyroid diseases, a study was performed comparing serum CK 8,18,19 levels in patients affected from thyroid carcinoma, adenoma, other benign thyroid diseases and healthy volunteers as controls. One hundred cases (65 patients and 35 controls) were examined. Thirty patients had thyroid carcinoma (18 papillary--PTC, 8 follicular--FTC, 4 medullary--MTC), 19 non-toxic goiter, 10 thyroid adenoma, 6 chronic thyroiditis and 35 healthy volunteers as controls. These controls were matched by age and sex. The mean value of CK in benign thyroid diseases (46.1 U/L) was significantly higher (p<0.02) than that in healthy controls (29.6 U/L). The mean value of CK in carcinomas (68.1 U/L) was significantly higher than that in healthy controls (p<0.01) and benign thyroid diseases patients (p<0.05). The positive rate of CK in thyroid carcinomas was 28.1%, while in benign thyroid diseases was 17.8%. The CK sensitivity for thyroid carcinomas was 28.1%, with a specificity of 80% and accuracy of 70.4%. In PTC patients the mean CK value was not significantly higher than in the benign diseases' group and in healthy subjects. No evident correlation between CK levels and tumor mass was found. In FTC patients the mean value was significantly higher than in the benign diseases' group and in healthy subjects. Large tumors showed the highest levels, while small tumor values were similar to the control ones. In MTC patients the mean value was significantly higher than in the benign diseases' group and in healthy subjects, with the highest peaks in large tumors and metastatic tumors. The detection of increased values in thyroid carcinomas with high metastatic potential (FTC and MTC) seems to confirm the role of these antigens in predicting the malignancy's degree of the neoplasm. These findings, if confirmed in larger series, could play an important role in assessing the CK 8,18,19 serum level as a real prognostic factor. Further repeated serum determinations after total thyroidectomy might indicate the role of CK 8,18,19 as serum markers predicting the risk of metastases.

Diagnostic value of CEA, CA 15-3, CA 19-9, CYFRA 21-1, NSE and TSA assay in pleural effusions

The aim of this study was to evaluate the individual and combined diagnostic utility of six tumor markers in patients with pleural effusion. Pleural and serum levels of carcinoembryonic antigen (CEA), carbohydrate antigen 15-3 (CA 15-3), carbohydrate antigen 19-9 (CA 19-9), cytokeratin fragment 19 (CYFRA 21-1), neuron-specific enolase (NSE) and total sialic acid (TSA) were assayed in 74 patients with pleural effusions (44 malignant and 30 benign). All tumor markers except TSA and NSE were increased in both serum and pleural fluid of patients with malignant diseases. Using the cut-off values 3 ng/ml, 14 U/ml, 5 U/ml, 8 ng/ml and 70 mg/dl for pleural fluid CEA, CA 15-3, CA 19-9, CYFRA 21-1 and TSA, respectively, the sensitivity (%) and specificity (%) of these tumor markers were as follows: CEA; 52/77, CA 15-3; 80/93, CA 19-9; 36/83, CYFRA 21-1; 91/90, TSA; 80/67, for differentiating malignant effusions from benign. When CA 15-3 and CYFRA 21-1 combined, the sensitivity and specificity were increased (100 and 83%, respectively). Classifying the malignant effusions as bronchial carcinoma and malignant pleural mesothelioma, CEA was shown to have the highest sensitivity and specificity (88 and 90%, respectively) while the combination of CEA with other tumor markers increased sensitivity but decreased specificity. According to our results, tumor markers are not suitable for the differential diagnosis of malignancy.

Serum CYFRA 21-1 is one of the most reliable tumor markers for breast carcinoma

BACKGROUND: The search for new tumor markers for breast carcinoma has been an area of vigorous study; nonetheless, to the authors' knowledge little new information has emerged beyond the clinical usefulness of CA 15-3. The authors studied serum CYFRA 21-1 in breast carcinoma based on evidence that breast carcinoma expresses cytokeratin 19 fragments and that CYFRA 21-1 is a specific antigen for cytokeratin 19 fragments. METHODS: The serum samples of 86 patients with primary breast carcinoma, 14 patients with recurrent breast carcinoma, 22 patients with benign mammary disease, and 25 healthy controls were provided for measurements of CYFRA 21-1, carcinoembryonic antigen (CEA), and CA 15-3. The relation between clinicopathologic features, prognosis, and disease free survival with serum CYFRA 21-1 titers was studied. RESULTS: There was no difference between the serum CYFRA 21-1 titers from patients with benign mammary disease and those from healthy controls. The sensitivities of CYFRA 21-1 for patients with International Union Against Cancer Stage IV and recurrent tumors were 60% and 64.2%, respectively, which were as high as those for CA 15-3 and superior to those for CEA. The hematogenous recurrence showed a very high sensitivity of 89%. According to the increments of T, N, and M factor numbers, the serum CYFRA 21-1 titers were elevated. No correlation between CYFRA 21-1 and CEA was observed and the correlation between CYFRA 21-1 and CA 15-3 was weak. The univariate and multivariate analyses for survival revealed that serum CYFRA 21-1 levels were an independent indicator of prognosis. CONCLUSIONS: The measurement of the serum CYFRA 21-1 titer in patients with breast carcinoma may be useful in monitoring for recurrence and evaluating the therapeutic effect in patients with advanced disease.
