title: Fine needle aspiration of the thyroid. Use in an average health care facility.
abstract: Fine needle aspiration of the thyroid is suggested as an initial diagnostic procedure in the evaluation of thyroid nodules. Some proponents of the procedure, however, believe that fine needle aspiration should be restricted to centers in which each operator obtains at least 500 biopsy specimens annually. Reviewed were 155 biopsy specimens obtained over three and one-half years, and the sensitivity of fine needle aspiration was determined to be 100 percent, the specificity to be 47.4 percent, and the accuracy to be 73 percent. A review of the literature revealed the sensitivity in larger series to range between 92 and 98 percent, specificity to range between 52 and 99.5 percent, and accuracy to range between 56.1 and 91.3 percent. The surgical yield of carcinoma was 64 percent in patients evaluated with fine needle aspiration, whereas the yield was 26 percent in those who underwent surgery without fine needle aspiration. These results appear to justify the use of fine needle aspiration in the evaluation of nodular thyroid disease at average-sized health care centers.
