Objective To investigate the effects of thyroid globulin antibody (TgAb) and thyroid peroxidase antibody (TPOAb) statuses on central lymph node (CLN) metastasis in patients with differentiated thyroid cancer (DTC).Methods A retrospective analysis was performed on 526 patients with DTC confirmed by pathology from nine participating institutions, who underwent the bilateral thyroidectomy plus bilateral CLN dissection. The clinicopathologic characteristics of different TGAb and TPOAb statuses of patients with DTC were compared, and whether the TGAb and TPOAb statuses were the independent risk factors of CLN metastasis in DTC patients or not was analyzed.Results All of 526 patients with DTC were included in this study, 152 were males and 374 were females. The age was (44±11) years old. There were 63 cases of TgAbTPOAb, 60 cases of TgAbTPOAb, 30 cases of TgAbTPOAb, and 373 cases of TgAbTPOAb. It was found that there was a significant difference in the gender among the four different antibody statuses of patients, that was, women with abnormal antibodies were more common (P<0.001), not found that there were related to the tumor size, blood vessel invasion, nerve invasion, CLN metastasis, tumor multifocality, and bilateral tumor or not (P>0.050). In this study, there were 389 cases of CLN with metastasis and 137 cases of CLN without metastasis. The results of multivariate analysis found that the age and gender of the patients were the independent risk factors (P<0.001), but didn’t find the TgAb and TPOAb Statuses and other factors were related to the CLN metastasis (P>0.050).Conclusions Statuses of TGAb and TPOAb aren’t obviously associated with CLN metastasis in patients with DTC, which is inconsistent with other studies. It needs to be further researched after expanding existing sample size and determining new predictive factors.
