Have malignancy rates increased in thyroidectomy cases

Abstract

ntroduction: This study aims to review thyroidectomy cases performed by a single surgeon in a single centre during the course of 1 year, to determine if the malignancy rate increased, and to compare the results with the liter ature. Material and methods: We retrospectively evaluated data of patients who underwent thyroidectomy between August 2018 and August 2019 in the General Surgery Clinic of our hospital. The malignancy rate was calculated and analysed according to the demographic data of the patients (gender and age), preoperative thyroid nodule sizes, and postoperative pathological mass sizes. Also, age, preoperative nodule size, and tumour size were all evaluated according to gender. Results: There were a total of 60 patients (14 (23%) male and 46 (77%) fe male). The pathology result revealed 16 (26.7%) malignant and 44 (73.3%) benign biopsies. The mean age was 46.72 ±12.08 years (20–74). We found that age, preoperative nodule size (cm), pathological tumour size (cm), and thyroid function tests were not significantly associated with malignancy. However, when age, preoperative nodule size, and tumour sizes were evalu ated according to gender, it was found that tumour sizes were significantly larger in men than in women (p < 0.001). In addition, the mean age of male patients was higher than that of women (p = 0.025). Conclusions: The malignancy rate has increased in the thyroidectomies per formed in our centre. This finding is consistent with relevant studies from the last 30 years. Therefore, it is likely that clinicians will continue to handle an increased number of thyroid malignancies
