In this study, the investigators look at the genetic expressional alteration which influenced on the early lateral neck node metastasis in thyroid papillary microcarcinoma.
Papillary thyroid carcinomas (PTCs) measuring 1.0 cm or less in diameter were defined as papillary thyroid microcarcinomas (PTMCs) by the World Health Organization (WHO), emphasizing on their benign behavior, probably of little clinical significance, which do not affect patients' survival. However, some reported that PTMCs may have aggressive behavior, can cause locoregional recurrences, cervical lymph node metastases, and even distant metastases. But till now, the characteristics of PTMCs with early lateral neck node metastasis were only reviewed and described by the clinicopathological parameters, and no analysis of PTMCs by the gene level is available. In these study, we investigate the genetic expressional alteration which influenced on the early lateral neck node metastasis in thyroid papillary microcarcinoma.

mRNA expression pattern by microarray analysis
mRNA expression differences between papillary thyroid microcarcinoma without lateral neck node metastasis and the one with lateral neck node metastasis. (The outcome will be measured within 24-hour after surgical removement using papillary thyroid microcarcinoma tissue.)
Time frame: 24-hour after surgical removement
