title: Fine needle thyroid aspiration: university hospital experience.
abstract: Fine needle thyroid aspiration (FNTA) as a diagnostic tool of thyroid disease was started at the University District Hospital (UDH) in 1983. FNTA was performed in 54 willing patients from December 1984 through December 1985. If no medical contraindications existed, thyroid surgery was recommended in order to assess diagnostic accuracy. Surgery was done in 34 (63%) patients; while not in 20:3 for medical reasons, 2 lost to follow-up, 3 refused, 7 had inappropriate FNTA, and 5 for unknown reasons. None had complications to FNTA. Cytology was classified as Class O: inadequate; Class 1: benign; Class 2: indeterminate; and Class 3: malignant. "Non-benign" cytology was obtained in 14 patients: 7 indeterminate (class 2) and 7 malignant (class 3). Four of these had carcinoma confirmed by surgery. Of the 19 with benign FNTA (class 1) only one has thyroid carcinoma. One patient had inadequate sample (Class O). The sensitivity was 80%, specificity 65%, and diagnostic accuracy 67%. All these statistical values are within the range reported in fifteen reviewed series. Thus, FNTA at UDH had a diagnostic value comparable to that described in the literature. It may be utilized as a safe, reliable tool complementary to clinical data in order to reduce the amount of unnecessary thyroid surgery, carry out earlier diagnoses of malignant nodules and increase the yield of carcinoma among those operated.
