Objective:
To evaluate the role of E-cadherin gene in the process of recurrent and metastasis of laryngeal cancer and to investigate the metastatic mechanism of laryngeal cancer.
Method:
Exploration of exon 5 and exon 7 of the E-cadherin gene by polymerase chain reaction (PCR), SSCP in the laryngeal cancer.
Result:
In normal laryngeal tissues, there was no E-cadherin gene mutation. E-cadherin gene mutation occured only in the primary carcinoma with cervical metastasis and recurrent laryngeal carcinoma. The mutation rate were 67.71% and 28.57% respectively. E-cadherin gene mutation occured more frequently in advanced carcinomas than that in early ones.
Conclusion:
E-cadherin gene mutation with its functional suppression was one of the molecular mechanisms of the laryngeal metastasis. It is suggested that E-cadherin may be a valuable prognostic marker for the carcinoma of larynx.

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...
