title: Expression of peanut agglutinin-binding carbohydrates correlates with nodal involvement in human lung adenocarcinoma.
abstract: The expression of 15 kinds of lectin-binding carbohydrates was examined histochemically in lung adenocarcinoma. The relation between expression of lectin binding carbohydrates and clinicopathologic factors was studied. The expression of peanut agglutinin (PNA) binding carbohydrates showed a high lymph node metastatic rate. Relation between PNA-binding carbohydrate expression and lymphatic vessel invasion was also recognized. Multivariate analysis showed that PNA-binding carbohydrate expression was an independent predictive factor of lymph node metastasis (odds ratio: 2.8) and of lymphatic vessel invasion (odds ratio: 5.2). The expression of PNA-binding carbohydrates would be a significant predictive factor for lymph node metastasis of lung adenocarcinomas.
