TUMOR
Radiologists 1 and 2 (Radiologist 1 has 12 years of expertise in thyroid imaging, and Radiologist 2 has 10 years of experience in thyroid imaging) independently evaluated and verified the preoperative ultrasound imaging for all patients without knowledge of the histological findings. ETE can be diagnosed according to AJCC standards if any of the two following criteria is met: (1) greater than 25 percent of the lesion's circumference is in contact with the thyroid capsule or the envelope line of the lesion's contact with the thyroid gland disappears; (2) a tumor of any size exceeds the thyroid capsule and invades subcutaneous soft tissue, larynx, trachea, esophagus, recurrent laryngeal nerve, carotid artery, or mediastinal vessels.
