Management of Locally Invasive Well-Differentiated Thyroid Cancer

Thyroid carcinoma invasion of the aerodigestive tract and recurrent laryngeal nerve (RLN) are important factors with increase in morbidity and mortality. Primary treatment is surgery; the decision about the extent of surgery is difficult, because preserving function is as essential as removal of the tumor. This article discusses the literature relating to the assessment of disease, surgical management, and adjuvant therapy for invasive thyroid cancer of the aerodigestive tract and RLN and makes suggestions based on the authors' experience.
