SUMMARY:

Objective: To analyze the malignancy rates of thyroid nodules classified in fine-needle aspiration puncture (FNAB) as categories III, IV, and V of Bethesda and to evaluate the importance of the association with ultrasound parameters for the decision regarding the therapeutic approach. Methodology: Electronic medical records were used to collect data referring to 253 nodules classified as Bethesda III, IV, and V that were surgically resected. Among the information in each case, there was the ultrasound classification of the Faculty of Medicine of the University of São Paulo (FMUSP) and the histopathological diagnosis (DHP). Subsequently, the variables were analyzed with each other using the IBM SPSS® program. Results: Nodules of categories III, IV, and V had 39.6%, 45.8% and 86.9% of malignancy, respectively. When the nodules were divided by the PAAF and ultrasound classification together, only Bethesda III showed statistical significance concerning DHP, with the percentage of malignant nodules being different for grades II (28.6%), III (39.1% ) and IV (67.9%) of the ultrasound. Besides, grade IV nodules had 75% malignancy when classified as Bethesda IV and 88.2% when V. When comparing PAAF categories III and IV about anatomy pathology, it was observed that the risk of malignancy for IV was 1.15 times greater than that of III, with 95% CI (0.80 - 1.67). However, this difference was not statistically significant (p = 0.446) Conclusions: Ultrasonography was essential to stratify the nodules classified as Bethesda III, identifying which ones have a greater tendency to conservative or surgical treatment. Also, grade IV nodules showed surgery to be the best initial approach in all categories of FNAB. The malignancy rates found in Bethesda III and IV cases are similar, suggesting the same approach for these groups of patients.
