Summary

Intra-operative cytological examination of the thyroid gland accurately diagnoses most thyroid disorders. While generally reliable, subtle cases of follicular carcinoma and adenoma require careful evaluation to avoid misdiagnosis.

Area of Science:

  • Oncology
  • Pathology
  • Endocrinology

Background:

  • Thyroid gland disorders encompass a range of benign and malignant conditions.
  • Accurate and timely diagnosis is crucial for effective patient management.
  • Intra-operative cytology offers a rapid method for assessing thyroid tissue during surgery.

Purpose of the Study:

  • To evaluate the accuracy and diagnostic utility of intra-operative cytological examinations of the thyroid gland.
  • To identify potential challenges and limitations of this diagnostic method.

Main Methods:

  • Analysis of intra-operative cytological findings from 757 patients undergoing thyroid surgery.
  • Correlation of cytological diagnoses with final histopathological results.

Main Results:

  • The method achieved an overall accuracy of 96.3% in diagnosing thyroid disorders.
  • Benign conditions and malignant tumors were correctly identified in most cases.
  • Challenges included differentiating well-differentiated follicular carcinoma (false negatives) and follicular adenoma, and atypical adenomas (false positives).

Conclusions:

  • Intra-operative thyroid cytology is a highly accurate tool for surgical decision-making.
  • Careful consideration of the clinical picture is essential to minimize diagnostic errors, particularly with specific tumor types.
  • The technique is reliable for most thyroid pathologies, with specific entities requiring cautious interpretation.
