DNA flow cytometry of thyroid neoplasms.

B B Kraemer, J R Srigley, J G Batsakis

    Archives of Otolaryngology (Chicago, Ill. : 1960)
    |January 1, 1985
    PubMed
    Summary

    Acridine orange flow cytometry revealed abnormal DNA content in some thyroid carcinomas, potentially differentiating indolent from aggressive disease. Further research is needed to confirm the role of nuclear DNA and proliferation in thyroid cancer prognosis.

    Area of Science:

    • Oncology
    • Cell Biology
    • Medical Diagnostics

    Background:

    • Thyroid carcinomas exhibit diverse clinical behaviors.
    • Accurate prognostic markers are crucial for effective patient management.

    Purpose of the Study:

    • To investigate the utility of DNA content analysis using acridine orange flow cytometry in differentiating thyroid lesions.
    • To explore the correlation between DNA ploidy and the clinical aggressiveness of thyroid carcinomas.

    Main Methods:

    • Mechanically dispersed cell suspensions from 23 thyroid lesions were analyzed.
    • Acridine orange flow cytometry was employed to determine DNA indices and assess proliferative activity.

    Main Results:

    • Eight of 14 thyroid carcinomas showed abnormal DNA indices, while six were diploid.

  • Diploid papillary carcinomas were associated with indolent disease in younger women.
  • Abnormal DNA content in papillary carcinomas correlated with aggressive disease in older men.
  • A benign adenomatoid nodule showed a near-diploid stemline with low proliferation.

    • Conclusions:

    • Nuclear DNA determination may aid in distinguishing between indolent and aggressive thyroid carcinomas.
    • Further investigation is required to establish the prognostic significance of proliferative activity in thyroid cancer.
