对CN 0期甲状腺乳头状癌患者行术中颈内静脉旁淋巴结活检的价值

The value of biopsy of lymph nodes alongside of internal jugular vein in surgery for papillary thyroid carcinoma patients at CN 0 stage

目的 探讨CN 0期甲状腺乳头状癌（PTC）患者术中行颈内静脉旁淋巴结活检的价值.方法 回顾性分析103例行手术治疗的CN 0期PTC患者的临床资料,统计颈内静脉旁淋巴结转移率,并对患者临床病理因素如性别、年龄、肿瘤大小、是否侵犯甲状腺被膜进行分析.结果 103例CN 0期PTC患者中,颈内静脉旁淋巴结转移32例（31.1％）.其中肿瘤侵犯甲状腺被膜者31例,颈内静脉旁淋巴结转移为21例（67.7％）,未侵犯被膜者72例,颈内静脉旁淋巴结转移为11例（15.3％）,两者差异有统计学意义（Х^2=27.85,P＜0.05）.结论 CN 0期的PTC患者,术中常规行颈内静脉旁淋巴结活检是十分必要的.甲状腺被膜是否受侵是影响颈内静脉旁淋巴结转移的重要因素.

Objective To explore the value of biopsy of lymph nodes alongside of internal jugular vein in surgery for papillary thyroid carcinoma（PTC） patients at CN 0 stage.Methods Clinical data of 103 PTC patients with operation at CN 0 stage were retrospectively analyzed.The lymph node ratio alongside of internal jugular vein was counted,and factors,such as gender,age,tumor size,capsular foreign invasion were analyzed.Results Of all 103 cases of papillary thyroid carcinoma at CN 0 stage,32 cases had lymph node metastasis alongside of internal jugular vein（31.1%）.Meanwhile 31 cases had the thyroid capsule invasion,and 21 cases had lymph node metastasis alongside of internal jugular vein（67.7%）.The rest 72 cases had no the thyroid capsule invasion,and 11 cases had lymph node metastasis alongside of internal jugular vein（15.3%）,the difference was statistically significance（Х^2 =27.85,P 〈 0.05）.Conclusion Routine biopsy of lymph nodes alongside of internal jugular vein is necessary of papillary thyroid carcinoma patients at CN 0 stage.Whether the thyroid capsule is invased which is important factors affecting lymph node metastasis alongside of internal jugular vein.
