6. Comment on invaded characteristics and the surgical management of locally invasive differentiated thyroid cancer
Main Article Content
Abstract
We conducted this study to describe the lesions, surgical techniques and evaluate the early results of surgery to treat differentiated thyroid carcinoma with tumors invading the glandular capsule. This was a descriptive, prospective study on 83 patients surgically treated at the Department of Thoracic Surgery - Central Military Hospital 108, from January 2013 to March 2021. Results: the average of age was 45.4 ± 12.2, the female/male ratio was 7.3/1. Invasion of the glandular capsule can occur at 28.9% even when the tumor size is small ≤ 1cm. Common invaded structures includestrap muscle, recurrent laryngeal nerve, and trachea at 38.5%, 25.3%, and 14.4%, respectively. Shaving excision technique was selected to excise tumor while preserving the invaded structure achieved a high rate of success: recurrent laryngeal nerve reaching 95.2%, tracheal and esophagus reaching 100%. Recording results up to 6th month post surgery showed that early postoperative complications were mainly temporary: hypoparathyroidism (20.5%), vocal cord paralysis (1.2%), no tumor or lymph node recurrence has been recorded.
