Bethesda IV-V tiroid nodüllerinin değerlendirilmesi: klinik deneyim

Abstract

Introduction: The malignancy rate in cases operated for thyroid nodule is approximately 5-10%, and although this rate shows significant differences according to Bethesda categories, there is a high risk of malignancy in categories IV and V compared to other categories. In our study, we examined the clinicopathological factors affecting the success of cytological diagnosis in nodules diagnosed with Bethesda IV-V. Material and Method: A total of 780 patients who were diagnosed with thyroid nodules and underwent surgery at our center between 2011 and 2021 were included in the study. The preoperative cytological diagnoses of the patients were categorized using the Bethesda classification system. The demographic data of the patients, Bethesda classification of the nodules, and postoperative histopathological examination results were evaluated in subgroups, and their significance was determined. Results: The age group with the highest number of cases was 45-59 years, and the female/male ratio of the whole cohort was 3:1. The rate of palpable nodules was 41.8% for the malignant diagnosis group and 58.2% for the benign diagnosis group. In both malignant and benign groups,
