Higher body mass index and larger waist circumference may be predictors of thyroid carcinoma in patients with Hürthle-cell lesion/neoplasm fine-needle aspiration diagnosis

Summary Objective High body mass index (BMI) has been found to be associated with raised thyroid cancer risk, particularly in women. We examined the associations for BMI and waist circumference (WC) with thyroid cancer risk among women with Hürthle‐cell lesion/neoplasm (HLN) on fine‐needle aspiration biopsy (FNAB) with the hypothesis that BMI and WC could guide the management of these challenging indeterminate lesions. Methods This cross‐sectional study included 224 women with HLN who underwent thyroidectomy. In all patients, TSH and thyroid auto‐antibodies were evaluated, and thyroid nodule features were recorded. Patients were grouped according to BMI (
