Papillary carcinoma of the thyroid gland. Analysis of 94 cases with preoperative fine needle aspiration cytologic examination.
From 1979 to 1983, 94 papillary carcinomas of the thyroid gland were examined histologically in our institute after a preoperative cytologic examination. Material for cytologic examination was obtained using fine needle aspiration (FNA) biopsy. Eighty-five (90.4%) of the 94 examined cytologic smears were representative. Among these 85 cases suspicion for malignancy or malignancy itself was found in 64 cases (75.3%). The remaining 21 smears, classified as cytologically not as suspect for malignancy, were reclassified and the previous diagnosis had to be revised in one case. In the other 20 cases no clue for malignancy could be demonstrated even after reexamination. In the 85 cases with representative cytologic findings, tumor size was determined on surgical material, in order to establish how many carcinomas with a diameter less than 3 cm could not be reached by FNA biopsy. Except for one case, all carcinomas with negative preoperative cytologic findings had a diameter less than or equal to 3 cm. The question arising is the possibility of improving the accuracy of FNA biopsy in tumor detection within cold nodules of the thyroid by combined use of scintigraphy and ultrasound-guided FNA biopsy.
