title: Management of the neck in thyroid cancer.
abstract: The incidence of nodal metastasis in differentiated thyroid cancer ranges between 40% to 75%. Elective neck dissection is generally not advised in patients with differentiated thyroid cancer; however, if clinically apparent nodal disease is noted in the tracheoesophageal groove during surgery, central compartment clearance is advised. If clinically apparent nodal disease is present in the lateral compartment of the neck, modified neck dissection preserving the sternomastoid, accessory nerve, and jugular vein is advised. The "berry picking procedure" is generally not recommended because of the higher incidence of regional recurrence. Due consideration should be given for parathyroidal transplantation if the blood supply to the parathyroids is damaged during central compartment clearance. The incidence of lymph node metastasis is highest in young patients, however, lymph node metastasis has no bearing on long-term survival. There seems to be a higher incidence of regional recurrence in elderly individuals. If patients present with bulky nodal disease, consideration may be given for postoperative radioactive iodine dosimetry and ablation if necessary. Differentiated thyroid cancer represents a unique disease in the human body, where lymph node metastasis has no prognostic implication. Aggressive surgical clearance is advised in patients with medullary thyroid cancer in the central compartment and the jugular chain lymph nodes.
