ntroduction: Thyroid diseases particularly nodular lesions are among the most common diseases of human. Approximately 5% of the populations have palpable thyroid nodules which are detected in the routine Autopsy. Nearly 95% of thyroid nodules are benign wherease malignant nodules include 5% of them. Fine needle aspiration (FNA) has been recognized as a simple, inexpensive and available procedure for rapid diagnosis. The objective of this study was to determine the value of FNA in thyroid diagnosis.
Material and Methods: In this retrospective research, 536 patients with thyroid nodules reffered for FNA or hospitalized for thyroid surgery in Imam Reza Hospital from March 2002 until March 2005 were studied. Individual and laboratory data were gathered in a questionnaire and analyzed by descriptive statistics.
Results: This study included 107 men and 429 women and the average age of patients was 40 years. Out of 536 patients 12.7% had malignant, 70.3% benign and 8.6% yield suspicious results and 2.4% of FNAs were insufficient. Comparing the results of FNA and biopsy, FNA had the specificity of 89.5%, sensitivity of 91.5%, and accuracy of 93.7%; negative and positive predictive values were 80.9% and 95.5% respectively.
Conclusion:These results reemphasized that, FNA is a simple and non invasive procedure and if performed carefully and evaluated by an expert pathologist is of high sensitivity and specificity.
