Abstract: | Objective:To investigate the indications of lateral neck lymph node dissection in patients with papillary thyroid carcinoma harboring BRAFV600Emutations.Methods:From January 2018 to August 2019,80 patients with papillary microcarcinoma who underwent total thyroidectomy and lateral neck lymph node dissection at Sichuan Cancer Hospital&Cancer Institute were retrospectively analyzed.The BRAFV600Egene was sequenced,and patients were assigned into the gene mutation group(group A)and the no-gene mutation group(Group B)based on sequencing results.There was no significant difference in the preoperative age and sex,so as to explore the cervical lymph node metastasis after surgery;stageⅡ:Fifty patients with BRAFV600Emutations were assigned into two groups:the lymph node metastasis group(Group C)and the no-metastasis group(Group D).Univariate and multivariate analyses according to sex,age,tumor diameter,tumor location,thyroglobulin levels,anti-thyroglobulin antibody levels,tumor invasion,thyroid function,tumor multifocality,and central lymph node metastasis were performed.Results:Among the 80 patients,50 had BRAFV600Emutations(group A),while 30 did not(group B).There were no significant differences in preoperative age,sex,thyroid function,tumor location,and multifocality between groups A and B(P>0.05).Postoperative cervical lymph node metastasis was significantly more frequent in group A than in group B(60%vs.27%,P=0.004).Among patients with BRAFV600Emutations,12(24%)had lateral neck metastasis(P=0.038),20(40%)had central lymph node metastasis with lateral neck lymph node metastasis(P=0.011),19(38%)had lateral neck lymph node metastasis(P=0.049).And 19(38%)had lateral neck metastasis with tumor diameter greater than 7.5mm(38%)(P=0.021);there were no statistically significant differences in gender,presence of Hashimoto's thyroiditis,thyroglobulin,anti-thyroglobulin antibodies,tumor invasion,and multifocal status of ipsilateral cervical lymph node metastasis(P>0.05).Conclusions:Patients with BRAFV600Emutations were more likely to develop lateral cervical lymph node metastasis.Age<55 years,tumor diameter≥7.5 mm,tumor located in the upper,middle,and central neck regions were risk factors for lateral cervical lymph node metastasis in papillary thyroid carcinoma harboring BRAFV600Egene mutations. |
