Abstract

Objective: To review indications and diagnostic results of thyroid cancer by fine-needle aspiration (FNA) and frozen section at Military Hospital 103. Subjects and methods: Retrospective study on patients were diagnosed with thyroid cancer according to histopathological results. Compare the cytological and immediately histopathological results with the HE stain results. Results: 106 thyroid cancer patients underwent total thyroidectomy. Preoperative fine needle aspiration cytology was performed for 100% of cases, the results: identified of 51 patients with cancer (rate 48.1%) and 50 patients (rate 42.7) %) suspected thyroid cancer; 4 cases were diagnosed as benign. Frozen-section was mainly indicated for patients with suspected of malignancy by FNA results (90.9%) or macroscopic lesion during operation (9,1%). The histopathologic type identification of frozen section test were consistent with HE stain at rate of 85.5%; frozen section test did not identify follicular and columnar variants of papillary thyroid carcinoma (14.5%). Conclusions: The efficiency of thyroid cancer diagnosis by FNA was 48.1%. Frozen section should be indicated for cases with FNA results or macroscopic lesions suspected of thyroid cancer to improve diagnostic results.
