Brief Summary:
In this study, the investigators look at the genetic expressional alteration which influenced on the early lateral neck node metastasis in thyroid papillary microcarcinoma.

Condition or disease
Papillary Thyroid Microcarcinoma

Detailed Description:
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.

Outcome Measures

Primary Outcome Measures :
  1. mRNA expression pattern by microarray analysis [ Time Frame: 24-hour after surgical removement ]
    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.)


Biospecimen Retention:   Samples With DNA
mRNA extract from Thyroid tissue 2mmx2mmx2mm (nomal thyroid and papillary thyroid microcarcinoma >5mm)
