Evaluation of US-Guided Thyroid Cytology

Aim of the study: Ultrasound (US) guided fine-needle aspiration biopsy (FNAB) is today an affirmative way to perform cytology for thyroid diseases. The goal of this study was to present the advantage of US-guided FNAB and an evaluation our results over the last 21 years. Methods: We used standard ultrasound equipment with a 7, 5-13 MHz linear probe. FNAB was performed under US guidance with “ free hand” technic. From 1984 to 2004, we performed 150313 US neck examinations, and 75246 FNAB in 41803 patients. The indications for US-guided FNAB were done on the basis of US examination. Physicians who make a US decide which nodule and which place need cytological verification. Results: Through 1995 we diagnosed an average of 84 thyroid carcinoma per year (operatively proved). In the last 9 years we diagnosed an average of 113 thyroid carcinoma per year. This is half of all new detected malignant thyroid tumors in Croatia per year. About 200 other tumors per year were diagnosed (follicular tumor, Hürthle cell tumor, adenoma, metastases in thyroid, etc.), which also need a operative treatment. Other patients were treated more conservatively. Conclusion: With US and US-FNAB it is possible discriminate the nodule suspected of a tumor (malignant or benign) which may need surgery and pathohistological verification, and others which can be safely followed up by sonography. The limitation on US diagnosis is tumors less then 0, 3 mm. Based on our lengthy experience, clear indications and team work, thyroid diseases can be diagnosed early and precisely. Thyroid tumors can be adequately treated and in a timely manner. In this way the mortality and morbidity of thyroid tumor diseases are very small.
