ABSTRACT

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(x2 =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.
