IS FINE NEEDEL ASPIRATION CYTOLOGY A VALID DIAGNOSTIC TOOL IN NODULAR GOITER?

Abstract

Background: Fine needle aspiration cytology (FNAC) is commonly used tests for diagnosis of thyroid nodules. Is available procedure and provides specific diagnosis rapidly with minimal complications. Aim: To assess the validity of FNAC in the evaluation of thyroid nodules performed at our institution and to compare our results with other studies elsewhere.Patients and methods: This study was conducted on 51 consecutive patients who underwent FNAC for diagnosis during the period from Feb 2012 -- Feb 2015. The final histopathological diagnosis was considered the gold standard. Results: The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of FNAC for the diagnosis of neoplastic thyroid nodules were 84.6%, 97.3%, 94.1%, 91.6%, 94.8% respectively. Papillary carcinoma was the common type in neoplastic group (53.8%).Conclusion: Our study suggests that FNAC is a sensitive, specific and accurate initial diagnostic test for the preoperative evaluation of patients with thyroid nodules. Our results are comparable with current published articles and the clinician should be encouraged to use FNAC as the initial modality in assessment of thyroid nodules.
