[Analysis of lymph node metastasis factors in papillary thyroid microcarcinoma]
1Department of Otolaryngology, Head and Neck Surgery, Renji Hospital of Shanghai Jiaotong University, 200001, China.
Objective:
To analyze the factors of lymph node metastasis in papillary thyroid microcarcinoma and to evaluate the significance of the selective neck dissection.
Method:
Records of 82 patients with papillary thyroid microcarcinoma were retrospectively analyzed. Sixty patients were received a selective neck dissection (Group 1), while twenty-two were not (Group 2).
Result:
In Group 1, 13 patients were found metastasis. The incidence of metastasis was 21. 67% (13/60). The frequency of nodal metastasis with a carcinoma < 0.7 cm was 4.76%, while > or = 0.7 cm was 30.77% (P < 0.05). All patients were followed-up from 9 to 14 years (mean 59.8 months). No patients relapsed or died, and no one was found distant metastasis.
Conclusion:
The papillary thyroid microcarcinoma had a high tendency to metastasize. It is more significant to perform selective neck dissection in tumors > or = 0.7 cm.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
