PREOPERATIVE THYROID FINE NEEDLE ASPIRATION BIOPSY FINDINGS IN PATIENTS UNDERGOING TOTAL THYROIDECTOMY FOR NODULAR GOITER
Abstract
Objective: Our purpose was to retrospectively investigate the postoperative histopathological results of the 53 patients who underwent total thyroidectomy operation at our hospital and compare them to their preoperative ultrasound-guided fine-needle aspiration biopsy (TFNAB) results.
Methods: Surgical records of the patients were reviewed together with preoperative thyroid fine-needle aspiration cytology (TFNAC) results. Results: The mean age (±SD) of 53 patients (12 males, 41 females) was 50±12.3 years (min: 19, max: 77). Mean age was 56.3±12.8 years (min: 34, max: 77) for males and 48.1±11.6 years (min: 19, max: 69) for females (p=0.14). Preoperative TFNAC results of 53 patients were: 11, Bethesda-1; 9, Bethesda-2; 14, Bethesda-3; 13, Bethesda-4, and 6 were Bethesda-5, respectively. Postoperative pathology results of 53 patients were of 23, nodular goiter; of 24, thyroid papillary carcinoma; of 3, chronic lymphocytic thyroiditis; 2, follicular adenoma;1, amyloidosis, respectively. The patients who were diagnosed as papillary thyroid carcinoma were determined malign; the others were determined as benign. So the ratio of malignancy of the patients who were operated was 45%. The rate of malignancy was 30% for patients with TFNAC results indicating Bethesda-1 and Bethesda-2 which did not strongly suggest malignancy but who underwent total thyroidectomy on the basis of other clinical manifestations; for patients operated due to a higher probability of malignancy as suggested by TFNAC results indicating Bethesda-3 and above categories, the malignancy rate was 55%.
Conclusion: TFNAC results should be taken into account in addition to clinical and ultrasonographic features when considering surgery for such patients.
