    Abstract:
    Objective: To examine the correlation factors of contralateral central lymph node metastasis in unilateral papillary thyroid carcinoma with lateral cervical lymph node metastasis. Methods: The clinical data of patients with unilateral papillary thyroid carcinoma who underwent total thyroidectomy and bilateral central lymph node dissection and ipsilateral cervical lymph node dissection from June 2016 to June 2018 at Department of Thyroid Surgery, West China Hospital, Sichuan University were analyzed retrospectively. A total of 317 patients, including 87 males and 230 females, aged (41.4±12.1) years (range: 16 to 75 years), were enrolled in this study. The risk factors of contralateral central lymph node metastasis were analyzed by χ2 test and Spearman correlation analysis. Results: There were 116, 69, 269, and 181 cases of pretracheal lymph node, prelaryngeal lymph node, ipsilateral central lymph node and contralateral central lymph node metastasis, respectively, and 16 cases of skipping metastasis. Univariate analysis showed that contralateral central lymph node metastasis was associated with gender, maximum tumor diameter, capsule invasion, pretracheal lymph node metastasis, prelaryngeal lymph node metastasis, and ipsilateral central lymph node metastasis (all P<0.05). Spearman correlation analysis showed that male (rs=0.162, P=0.004), maximum tumor diameter>10 mm (rs=0.184, P=0.001), capsule invasion (rs=0.135, P=0.016), pretracheal lymph node metastasis (rs=0.394, P<0.01), prelaryngeal lymph node metastasis (rs=0.272, P<0.01) and ipsilateral central lymph node metastasis (rs=0.203, P<0.01) were independent correlation factors for contralateral central lymph node metastasis. Conclusion: For patients with unilateral papillary thyroid carcinoma with ipsilateral cervical lymph node metastasis, bilateral central lymph node dissection should be considered if male, tumor diameter>10 mm, capsule invasion, pretracheal lymph node metastasis, prelaryngeal lymph node metastasis, or ipsilateral central lymph node metastasis. 目的： 探讨患侧颈侧区淋巴结转移的单侧甲状腺乳头状癌对侧中央区淋巴结转移的相关因素。 方法： 回顾性分析2016年6月至2018年6月在四川大学华西医院甲状（旁）腺疾病外科诊疗中心行甲状腺全切+双侧中央区淋巴结清扫+患侧颈侧区淋巴结清扫的单侧甲状腺乳头状癌患者的临床资料。共纳入317例患者，男性87例，女性230例，年龄（41.4±12.1）岁（范围：16~75岁），对侧中央区淋巴结转移的相关因素采用χ²检验单因素分析及Spearman相关性分析。 结果： 有气管前淋巴结、喉前淋巴结、患侧中央区淋巴结及对侧中央区淋巴结转移者分别为116、69、269、181例，跳跃性转移者16例。单因素分析结果显示，对侧中央区淋巴结转移与性别、肿瘤最大径、被膜受侵、气管前淋巴结转移、喉前淋巴结转移及患侧中央区淋巴结转移有关（P值均<0.05）；Spearman相关性分析结果显示，男性（rs=0.162，P=0.004）、肿瘤最大径>10 mm（rs=0.184，P=0.001）、被膜受侵（rs=0.135，P=0.016）、气管前淋巴结转移（rs=0.394，P<0.01）、喉前淋巴结转移（rs=0.272，P<0.01）及患侧中央区淋巴结转移（rs=0.203，P<0.01）是对侧中央区淋巴结转移的独立相关因素。 结论： 患侧颈侧区淋巴结有转移的单侧甲状腺乳头状癌患者，如存在男性、肿瘤最大径>10 mm、被膜受侵、气管前淋巴结转移、喉前淋巴结转移或患侧中央区淋巴结转移等因素，对侧中央区淋巴结存在转移的可能性较高，可考虑行双侧中央区淋巴结清扫。.
