Thyroid carcinoma invading the upper aerodigestive system.

摘要: Well-differentiated thyroid carcinoma infrequently invades the upper aerodigestive tract. However, when invasion occurs it is source of significant morbidity and excess mortality. The most common structures invaded by are recurrent laryngeal nerves, larynx, pharynx, esophagus, which can produce symptoms airway insufficiency, dysphagia, hemoptysis. Locally invasive often be successfully treated while preserving function airway. If tumor involves only wall larynx or trachea without intraluminal extension, "shaving" from will local control rates comparable to more radical destructive procedures. Intraluminal extension a serious problem that usually requires resection portion Even in this situation, partial tracheal with preservation might possible should used. Adjuvant therapy using radioiodine external beam radiotherapy considered an integral part any treatment plan for these tumors. These modalities significantly reduce rate recurrence symptomatic disease.
