  • Title: Flow cytometric DNA measurements in human thyroid tumors.
    Author: Christov K.
    Journal: Virchows Arch B Cell Pathol Incl Mol Pathol; 1986; 51(3):255-63. PubMed ID: 2874658.
    Abstract:
    By means of flow cytometry (FCM), DNA distribution pattern and the fraction of cells in the various phases of the cell cycle were studied in 52 samples of normal thyroid tissues, follicular adenomas, follicular carcinomas, medullary carcinoma and fibrosarcomas. In the normal thyroid tissues and follicular adenomas DNA diploid cell populations only were found. Among 20 follicular carcinomas in 13 cases (65%) together with the DNA diploid cells, DNA aneuploid cell lines were also observed. S-phase fraction in follicular adenomas is higher than in the normal thyroid tissues and lower than those in thyroid carcinomas. The percentage of S-phase cells in DNA aneuploid populations is significantly higher (S = 19 +/- 9.3%) than in the diploid cell lines (S = 3.7 +/- 2.6%). DNA aneuploid cell populations were predominantly observed in carcinomas with a high degree of morphological anaplasia.
