Summary
Intraoperative frozen-section diagnosis in thyroid surgery is reliable, with 92% concordance and 99.8% specificity. However, sensitivity for certain thyroid cancers, like follicular and papillary, remains lower.
Area of Science:
- Endocrinology
- Surgical Pathology
Context:
- Intraoperative frozen-section diagnosis aids surgical decision-making during thyroid procedures.
- Accurate intraoperative assessment is crucial for determining the extent of surgery and guiding patient management.
Purpose:
- To evaluate the diagnostic accuracy and limitations of intraoperative frozen-section analysis in thyroid surgery.
- To correlate frozen-section findings with final histopathological diagnoses.
Summary:
- This retrospective study analyzed 1534 thyroid frozen sections, achieving 92% concordance with final histology.
- Overall specificity was 99.8%, but sensitivity was 67%, notably lower for follicular (42%) and papillary (64%) thyroid cancers.
- Discordances were primarily linked to microfollicular lesions, impacting overall sensitivity.
Impact:
- Intraoperative frozen-section analysis demonstrates high reliability for thyroid surgery, supporting its continued use.
- Emphasizes the need for enhanced collaboration among pathologists, radiologists, and clinicians for optimal patient outcomes.
- Highlights areas for improvement, particularly in differentiating microfollicular lesions.
