Abstract: Objective To analyze retrospectively the factors related with lymph node metastasis in thyroid microcarcinoma.Methods One hundred and eieghty-seven cases of thyroid microcarcinoma were collected from the First Affiliated Hospital of Dalian Medical University from January 2007 to December 2011,who were operated at the first time and confirmed by pathology.According to the occurrence of lymph node metastasis,they were divided into metastasis group and non-metastasis group.The factors related were analyzed retrospectively.Results The total metastasis rate was 26.7％ (50/187),the metastasis rate of central lymph node was 22.9％ (43/187),and the metastasis rate of lateral lymph node was 11.8％ (22/187).Tumor's diameter more than 5 mm,multiple foci and extrathyroidal extension were related to neck lymph node metastasis of thyroid microcarcinoma (P ＜ 0.05).Conclusions Neck lymph node metastasis was seen most common in central lymph nodes.Tumor size,multiple foci and extrathyroidal extension were related to neck lymph node metastasis of thyroid microcarcinoma,operation therapy should be routinely performed.
