  • Title: Fine needle aspiration biopsy of thyroid nodules.
    Author: Caplan RH, Strutt PJ, Kisken WA, Wester SM.
    Journal: Wis Med J; 1991 Jun; 90(6):285-8. PubMed ID: 1871995.
    Abstract:
    Between April 1982 and December 1988, we performed 611 fine needle aspiration (FNA) biopsies in 502 patients with solitary thyroid nodules. The biopsy results were classified as follows: unsatisfactory, 19%; benign, 53%; suspicious, 23%; and malignant, 5%. Malignant lesions were found at surgery in 24 of 25 patients with malignant cytology and 31 of 68 patients with suspicious cytology. Autonomous nodules, obviating the need for surgery, were detected in 5 of 36 (14%) patients with cytology suspicious for follicular neoplasm. We conclude that FNA biopsy of the thyroid nodule is a safe and accurate diagnostic test. Thyroid scintigraphy remains useful in patients with cytologic results suspicious for follicular neoplasm. A cost-effective strategy for managing thyroid nodules is presented.
