study on diagnostic value of fine needle aspiration [FNA] test in determination of malignant thyroid nodules based on pathologic findings

ABSTRACT

thyroid nodules are very common and of course the most important point to approach thyroid nodules is to find out whether the nodule is benign or malignant. biopsy is the most definite way to differentiate malignant nodules from benign ones and this is at least, equal with a labectomy. FNA is a method which was first introduced in 1930 and led to a decrease in the number of thyroidectomy nowadays this is the best way to approach the thyroid nodules this study was performed on 100 cases of thyroidectomy to find out the sensitivity, specificity and accuracy of FNA in diagnosis of malignant thyroid nodules. candidates for thyroidectomy who referred to mofateh clinic in yasuj were evaluated by FNA and also open biopsy. FNA results showed 78% +/- 15% sensitivity, 91% +/- 13% specificity and 89% +/- 13% accuracy. positive predictive value of FNA was 75% +/- 35% and negative predictive value was found to be 93% +/- 20% considering the results of this study, FNA can be used instead of biopsy in approach to thyroid nodules and this will help to prevent unnecessary operations and high dose of radiation to neck
