BACKGROUND: Fine-needle aspiration (FNA) is a useful method for evaluating @entity1376 ; however, its role is still controversial. The aim of this study was to assess the utility of ultrasound-guided thyroid FNA in detecting @entity5 in @entity1 with @entity1376 in Oman. MATERIALS AND METHODS: This was a retrospective study where all @entity1 with @entity1376 seen at the Sultan Qaboos University Hospital endocrinology clinic in Oman in 2005 were evaluated. The thyroid FNA results were grouped into either @entity5 (negative result). They were compared to those of final histopathological examination in order to calculate the value of the test in diagnosing @entity5 . Analyses were evaluated using descriptive statistics. RESULTS: A total of 272 @entity1 were included in the study. The mean age was 39  13 years with an age range from 5 to 85 years. The majority of the @entity1 were females (n=236; 87%). The results of thyroid FNA revealed that 6% (n=15) of the @entity1 had @entity5 while histopathological results showed that the proportion of subjects with @entity5 was 18% (n=49). Out of the 15 cases identified to have @entity5 by thyroid FNA, only 53% (n=8) of the subjects were confirmed to have @entity5 by biopsy. Overall, the results of the tests were poor, revealing a sensitivity of 16%, specificity of 97% and a diagnostic accuracy of 82%, with a positive predictive value of 53% and a negative predictive value of 84%. CONCLUSION: Thyroid FNA is not a useful test in differentiating @entity1376 from @entity5 , as more than 80% of the @entity5 go unnoticed.
