A Rare Invasion Route for Differentiated Thyroid Carcinoma

Thyroid cancer can infiltrate the aerodigestive tract, which consists of the respiratory tract and upper digestive tract. In some rare instances, the cancer can invade the wall shared by the esophagus and the trachea. This study focuses on three specific cases of the aforementioned invasions and concludes that surgeons should be prepared to perform complete resection of cancer during the initial surgery to prevent potential downstream clinical consequences associated with these rare invasions.
