Background and objectives: The finding of a thyroid nodule is a very common occurrence in clinical practice. Management of thyroid nodules requires a multidisciplinary approach that may be eased by a high-resolution thyroid nodule clinic. We report our clinical experience and outcomes in a high-resolution thyroid nodule clinic.
Materials and methods: We conducted a retrospective analysis of 1674 thyroid nodules evaluated in a high-resolution clinic from an academic hospital between 2005 and 2011. ATA and ETA guidelines were used for thyroid nodules assessment.
Results: Of these 1674 nodules, 64.2% were solid, 45.7% hypoechogenic, and 6.3% showed microcalcifications. Mean nodule diameter was 1.96 cm. Fine-needle aspiration (FNA) was performed in 1303 nodules, and 61 (3.6%) were cancerous. Mean nodule diameter was similar between benign and malignant nodules (2.46 vs 2.58 cm, P=0.13). Increasing nodule size did not impact cancer risk.
Conclusions: In this cohort of 1674 thyroid nodules, most nodules were solid and hypoechogenic. Thyroid cancer prevalence was 3.6% and cancer rate was not associated with thyroid nodule size.
