ABSTRACT
Objective To study cervical central group (VI region) lymph node metastasis with papillary thyroid microcarcinoma and correlative influencing factors.Methods Clinical data of 215 papillary thyroid microcarcinoma patients undergoing surgery between Jan 2007 and Jan 2011 were analyzed retrospectively.Results All patients accepted bilateral thyroidectomy and bilateral cervical central group lymph node dissection.The total incidence of cervical central group lymph node metastasis was 36.7％ (79/215).Factors relating to cervical central group lymph node metastasis rate were:age (with one year elder,the likelyhood of lymph node metastasis was 0.935 times lesser),gender (the ratio of female to male was 0.202),the number of foci and the sum of the diameters of all lesions.Conclusions Patients with papillary thyroid microcarcinoma may suffer from lymph node metastasis of the cervical central group,and lymph node metastasis rate increases significantly in young or male patients,and when the lesions were multifocal or the sum of the tumor diameter ＞ 0.5 cm.
