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.

摘要

分化型甲状腺癌的淋巴结转移发生率在40%至75%之间。一般不建议对分化型甲状腺癌患者进行选择性颈部清扫术;然而,如果手术期间在气管食管沟发现临床上明显的淋巴结病变,则建议进行中央区清扫。如果颈部外侧区存在临床上明显的淋巴结病变,建议进行保留胸锁乳突肌、副神经和颈静脉的改良颈部清扫术。由于区域复发率较高,一般不推荐“摘莓样手术”。如果在中央区清扫过程中甲状旁腺的血供受损,应适当考虑甲状旁腺移植。年轻患者的淋巴结转移发生率最高,然而,淋巴结转移与长期生存无关。老年个体似乎区域复发率较高。如果患者出现巨大淋巴结病变,如有必要,可考虑术后放射性碘剂量测定和消融。分化型甲状腺癌是人体中的一种独特疾病,其中淋巴结转移对预后没有影响。对于甲状腺髓样癌累及中央区和颈链淋巴结的患者,建议进行积极的手术清扫。
