Summary
Fine needle aspiration cytology (FNAC) of thyroid nodules is a valuable diagnostic tool. This study found FNAC effective in identifying thyroid cancers, with a low false negative rate, aiding pre-operative evaluation.
Area of Science:
- Endocrinology
- Oncology
- Cytopathology
Background:
- Thyroid nodules are common, requiring accurate diagnostic methods.
- Fine needle aspiration cytology (FNAC) is a primary diagnostic technique for thyroid nodules.
- Distinguishing benign from malignant nodules pre-operatively is crucial for patient management.
Purpose of the Study:
- To evaluate the diagnostic utility of FNAC for thyroid nodules.
- To assess the accuracy of FNAC in detecting thyroid carcinomata.
- To determine the role of FNAC in the pre-operative assessment of thyroid nodules.
Main Methods:
- Review of 107 patient cases with thyroid pathological changes.
- Analysis of FNAC results compared to pathological findings.
- Calculation of diagnostic accuracy, including false positive and false negative rates.
Main Results:
- Nine cases of thyroid carcinomata were identified.
- Seven out of nine carcinomata showed abnormal FNAC cytology.
- One false negative result was recorded, with no false positive results.
Conclusions:
- FNAC is a highly effective method for diagnosing thyroid nodules.
- The technique demonstrates good sensitivity and specificity for detecting thyroid cancer.
- FNAC plays a significant role in the pre-operative evaluation of thyroid nodules, guiding surgical decisions.
