Abstract

Objectives: To review some clinical, ultrasound and intraoperative characteristics of differentiated thyroid carcinomas patient with extrathyroidal invading. Subjects and methods: Retrospective, descriptive study on 83 differentiated thyroid carcinoma patients who underwent operated at 108 Hospital, from January 2019 to March 2021. Results: The mean of age was 45.4 ± 12.2, the female/male ratio was 7.3/1. Hoarseness symptoms account for 8.7%. Ultrasound results: tumor diameter ≤ 20mm accounted for mainly (85.5%); images of hypoechoic mass, microcalcification, and irregular margins account for a high proportion, respectively 77.1%, 72.3% and 71.1%; Ti-rads groups IV and V account for the majority (90.4%); tumor broke the thyroid capsule reached the rate of 15.7%. Macromorphology injuries identified during surgery include breaking the capsule, extrathyroidal extension (ETE) into connective tissue 31.3%, ETE into muscle 39.8%, ETE into adjacent structures, including the recurrent nerve (25.3%), trachea (14.5%) and esophagus (8.4%). Invasion can occur even when the tumor size was ≤10mm (24 patients, accounting for 28.9%). Conclusion: Hoarseness symptoms, and thyroid capsule breaking images on ultrasound account for a low rate in differentiated thyroid carcinomas patients with extrathyroidal invasion. Invasion to adjacent structures accounts for a high rate (48.2%), even when the tumor diameter was ≤10mm (rate of 28.9%).
