Clinical Research of Regular Pattern of Cervical Lymph Node Metastasis in CN0 Papillary Thyroid Carcinoma

摘要

To investigate the regular metastasis pattern of cervical lymph nodes in CN0 papillary thyroid carcinoma and to define the proper surgery scope. Clinical data of the 1208 cases of CN0 papillary thyroid carcinoma patients undergoing surgery from Feb.2008 to Feb.2016 in the First Hospital of Jilin University were retrospectively analyzed. There were 572 (47.35%) PN+ cases and 636 (52.6551) PN0 cases.In CN0 cases, lymph node metastasis was most commonly detected in areaW, which was about 45.9451(555/1208) . When the tumor diameter was no less than 1.0cm, multifocal or capsule invaded, male, <;45years old, the rate of lymph node metastasis was significantly increased (P<;0.05). The scope of the cleaning should be expanded for high risk patients, such as large tumor, capsule invaded, multifocal, male, less than 45 years old, etc. Both endocrine suppression therapy and radioactive iodine therapy were effective to prevent the recurrence.
