Analysis Of Related Factors Of Lymph Node Metastasis In LN—prRLN Of Papillary Thyroid Carcinoma

ObjectivesTo investigate the risk factors of deep lymph node metastasis(LN-prRLN)of right recurrent laryngeal nerve(PTC)in papillary thyroid carcinoma.MethodA retrospective clinical study of 216 patients with PTC undergoing surgery between January 2008 and January 2016 was conducted.The central right paratracheal lymph nodes with recurrent laryngeal nerve(RLN)for the sector,divided into the recurrent laryngeal nerve shallow(VIa sub region)and the recurrent laryngeal nerve,correlation analysis patients age,gender,tumor size,multifocal and capsule invasion factors and lymph node metastasis.ResultThe 216 PTC patients,lymph node metastasis rate was 45.83%(CCLN)(99/216),sub region VIb lymph node metastasis rate was 19.91%(43/216),VIa and VIb sub region and lymph node metastasis rate was 13.89%(30/216),VIb and VIa sub region dish lymph node metastasis rate was 5.09%.(11/216).The incidence of complications associated with lymph node dissection in the VIb subregion was 5.55%(12/216).Multivariate analysis showed that tumor size,tumor number,tumor,although the degree of sub region VIa lymph node metastasis and invasion of neck lymph node metastasis is the independent influencing factors of PTC patients with B sub region VI lymph node metastasis.The cN0 patients were 179 cases,74 cases(74/ 179,24.66%)District VI there is a transfer of patients in each sub region in the ipsilateral paratracheal lymph node metastasis is the most common(43/179,24.02%).The right lymph node metastasis was divided into the anterior RLN metastasis(41 / 154,26.62%)and the LN-prRLNM(14 / 154,9.09%).A total of 117 patients with papillary thyroid microcarcinoma.The right lymph node metastasis was divided into the anterior recurrent laryngeal nerve metastasis(17 / 117,14.52%)and the recurrent laryngeal nerve metastasis(15 / 117,12.82%).ConclusionThe right CLND should be routinely explored for RLN deep regions.When the right PTC tumor diameter greater than 1 cm,multiple tumors,with extrathyroidal invasion or lymph node metastasis,complete CLND should include the removal of LN-prRIN.
