甲状腺乳头状癌右侧喉返神经深层淋巴结转移率及影响因素

Rate of deep lymph node metastasis and its influencing factors of right recurrent laryngeal nerve in papillary thyroid carcinoma

目的:探讨甲状腺乳头状癌(PTC)右侧喉返神经深层淋巴结(Ⅵb区)转移率及其影响因素。方法:收集我院2017年7月至2019年6月136例PTC患者的临床资料,分析Ⅵb区转移率及影响因素。结果:136例中,浅层淋巴结(Ⅵa区)转移96例(70.59%),Ⅵb区转移31例(22.79%)。清扫方式、病灶直径、Ⅵa区淋巴结转移、包膜侵犯与PTCⅥb区转移有关(P<0.05或P<0.01)。结论:右侧或双侧PTC患者应当行完整、彻底中央区淋巴结清扫,包括Ⅵb区清扫。

Objective:To investigate the rate of deep lymph node metastasis of right recurrent laryngeal nerve in papillary thyroid carcinoma(PTC)and its influencing factors.Methods:The clinical data of 136 cases of PTC from June 2017 to July 2019 in our hospital were retrospectively collected.The rate of deep lymph node metastasis of right recurrent laryngeal nerve and its influencing factors were analyzed.Results:Among the 136 cases,96 cases(70.59%)had superficial lymph node metastasis and 31 cases(22.79%)had deep lymph node metastasis.Deep lymph node metastasis of right recurrent laryngeal nerve in PTC patients was associated with lymph node dissection mode,lesion diameter,superficial lymph node metastasis and invasion of dorsal membrane(P<0.05 or P<0.01).Conclusion:Complete and thorough central lymph node dissection should be performed in patients with right or bilateral PTC,including the posterior lymph node of right recurrent laryngeal nerve.
