Correlation of increased twist with lymph node metastasis in patients with oral squamous cell carcinoma.

Purpose: To investigate the protein expression of Twist, Snail, and Slug in oral squamous cell carcinoma (OSCC) samples and evaluate the potential correlation between the expression status and clinicopathologic features in patients with OSCC.

Patients And Methods: Twist, Snail, and Slug protein expression was assessed by immunohistochemistry in a total of 60 OSCC samples and 10 normal oral mucosal samples. The associations between the protein expression and clinicopathologic parameters were mainly detected using the χ(2) test.
