The expression of E-cadherin and β-catenin in the patients with squamous cell carcinoma of the tongue (T1, 2) was examined by immunohisto-chemistry. E-cadherin and β-catenin expression in the tumor was graded as positive (+), heterogene-ous (±) and negative (-) respectively. The reduction of β-catenin expression and of E-cadherin was found in 67% of cases. Regarding the clinical fea-tures, the reduction of E-cadherin expression was significantly associated with cervical lymph node metastasis (p<0.05). Futhermore, the freqency of lymph node metastasis in E-cadherin (-) /β-catenin (-) tumors (70%) were higher than in E-cadherin (+) /β-catenin (+) tumors (8%) (p<0.01) . These results suggested that E-cadherin and β-catenin can be utilized as a diagnostic parameter which predicts the high incidence of occult cervical metastasis in squamous cell carcinoma of the tongue.
