Abstract:

Background: Thyroid nodules are frequent occurrences. This study aims to evaluate the risk of malignancy based on the ۲۰۱۵ American Thyroid Association Management: Guidelines for Adult Patients with Thyroid Nodules and Differentiated Thyroid Cancer. Methods: In this cross-sectional study, ultrasonography and clinical manifestations were compared with pathology findings to predict the risk of malignancy in thyroid nodules. Assessment of the ultrasound findings was based on the criteria recommended by The ۲۰۱۵ American Thyroid Association Management Guidelines for Thyroid Nodules. For the evaluation of the association between clinical and ultrasound findings with histopathology results, we used the chi-square and Fisher’s exact tests. The relative risk and prediction of malignancy was assessed by multiple logistic regression analysis. Data analysis was performed by the SPSS۱۹. The significance level was set at P<۰.۰۵. Results: From ۱۳۰ patients with thyroid nodules, ۱۱۰ (۸۴.۶%) were female. The mean age of participants was ۴۶.۱±۱۱.۵ years. Histopathology findings showed malignancy in ۱۷.۷% of the nodules, all of were papillary thyroid carcinoma. Multivariate logistic regression showed some of the ultrasonography parameters, absence of halo (P<۰.۰۰۱, OR=۲۸), taller than wide shape (P=۰.۰۰۱, OR=۱۸.۳), nodule size more than ۴ cm (P=۰.۰۴, OR=۱۲.۱), irregular margin (P=۰.۰۰۱, OR=۱۰.۰۶), solid or mixed composition (P=۰.۰۰۲, OR=۸.۱), hypoechoic (P=۰.۰۰۱, OR=۴.۵), lymph node positive  (P=۰.۰۰۲, OR=۴.۳), positive calcification (P=۰.۰۳, OR=۲.۰۸), positive internal vascularity (P<۰.۰۰۱, OR=۱.۰۵), and intermediate/high level of suspicion (P=۰.۰۰۱, OR=۱۲) could predict malignancy in patients with thyroid nodules. Conclusion: Based on increasing rate of thyroid cancer, in this study, the new and accurate ultrasound technique is recommended as alternative diagnostic method due non-invasive nature and lower cost used.
