Summary
Fine needle biopsy (FNB) and core needle biopsy (CNB) are effective for evaluating thyroid nodules. These methods help identify malignancy and reduce the need for diagnostic thyroidectomy.
Area of Science:
- Endocrinology
- Surgical Pathology
- Diagnostic Imaging
Background:
- Nodular thyroid disease is common, requiring accurate diagnostic methods.
- Fine needle biopsy (FNB) and core needle biopsy (CNB) are key diagnostic tools.
Purpose of the Study:
- To compare the efficacy of FNB and CNB in diagnosing nodular thyroid disease.
- To assess the diagnostic accuracy and complication rates of FNB and CNB.
Main Methods:
- Retrospective analysis of 150 patients with nodular thyroid disease.
- Review of 169 FNBs and 28 CNBs, with comparison of results.
- Analysis of surgical outcomes and histopathological diagnoses.
Main Results:
- Adequate material obtained in 97% of FNBs and 92% of CNBs.
- FNB sensitivity 86%, specificity 44% for neoplasia; CNB sensitivity 89%, specificity 67%.
- 60% of patients avoided surgery; 31% of operated specimens showed malignancy.
Conclusions:
- Both FNB and CNB are valuable for assessing thyroid nodules and detecting cancer.
- These biopsy techniques can decrease the necessity for diagnostic thyroidectomy.
- Clinical evaluation remains crucial in conjunction with biopsy findings for surgical decisions.
