[Prognostic significance of nuclear DNA content in highly malignant thyroid tumors].
The nuclear DNA content of tumour cells is correlated with the clinical outcome of a wide range of malignant disorders, among them thyroid neoplasia. The authors performed DNA determinations by means of the Feulgen cytofluorimetric method and demonstrate the connection between ploidy and biological aggressivity in cases of highly malignant thyroid tumours. The nuclear DNA content was measured in fresh surgical specimens from 53 patients suffering from malignancy, 13 of which proved pathohistologically to be highly malignant: 8 were anaplastic giant cell carcinomas, 3 squamous cell carcinomas and 2 were malignant lymphomas. 4 of the 8 giant cell carcinomas contained co-existent well-differentiated areas, namely follicular carcinomas in 3 patients and a papillary carcinoma in the 4th patient. 11 of the patients died of cancer, 9 within the 1st year. A different DNA distribution was found in the two survivors over a 10-year follow-up period. One of them showed a diploid cell population and the other facultative polyploidy, as opposed to the aneuploid pattern found in the 11 deceased patients. Both patterns confirm the correlation with a favourable outcome.
