Summary
This study reviewed 92 thyroid disease surgeries, finding 11% were thyroid cancer. Frozen section missed 3 cancers, highlighting the importance of permanent sections for accurate thyroid cancer diagnosis.
Area of Science:
- Endocrinology
- Surgical Pathology
- Oncology
Background:
- Thyroid disease management involves surgical intervention for various conditions.
- Accurate preoperative and intraoperative diagnosis is crucial for effective treatment.
- Histopathological examination remains the gold standard for thyroid lesion classification.
Purpose of the Study:
- To review surgical outcomes for diverse thyroid diseases.
- To evaluate the diagnostic accuracy of frozen section analysis in thyroid cancer.
- To identify the incidence of malignancy in cold thyroid nodules.
Main Methods:
- Retrospective review of 92 patients undergoing thyroid surgery.
- Analysis of histopathological findings from adenoma, thyrotoxicosis, cancer, and Hashimoto's thyroiditis.
- Comparison of frozen section and permanent section diagnoses for thyroid cancer.
Main Results:
- Adenomas comprised the largest group (61%), followed by thyrotoxicosis (24%), cancer (11%), and Hashimoto's thyroiditis (4%).
- Malignancy was detected in 9% of cold nodules.
- Frozen section examination identified 3 thyroid cancers, while permanent sections revealed an additional 3 missed cases.
Conclusions:
- Surgical intervention for thyroid diseases encompasses a range of pathologies.
- Permanent section examination is essential for definitive thyroid cancer diagnosis, as frozen section can miss cases.
- A significant proportion of cold nodules may harbor malignancy, necessitating careful evaluation.
