Summary
Frozen sections (FS) aid thyroid nodule surgery when fine-needle aspiration (FNA) is suspicious. FS can be omitted if FNA is positive for malignancy, improving surgical decisions.
Area of Science:
- Endocrinology
- Surgical Pathology
- Oncology
Background:
- Fine-needle aspiration (FNA) has reduced the use of frozen sections (FS) for thyroid neoplasms.
- The clinical utility of FS in thyroid nodule assessment alongside adequate FNA requires further clarification.
Purpose of the Study:
- To evaluate the role of FS in the surgical management of thyroid nodules when FNA provides a conclusive finding.
Main Methods:
- Retrospective chart review of 85 patients undergoing thyroid surgery over a 3-year period.
- Inclusion criteria required both adequate FNA and FS results.
Main Results:
- FS demonstrated 86% accuracy, significantly higher than FNA's 40%.
- When FNA was suspicious (71 cases), FS confirmed malignancy in 19 and deferred surgery in 66, though 18% of deferred cases were ultimately malignant.
- FS was accurate in 91% of cases when FNA indicated malignancy.
Conclusions:
- FS remains valuable in thyroid nodule surgery, particularly when FNA results are suspicious.
- FS may be unnecessary if FNA definitively identifies malignancy, streamlining surgical planning.
