Carbohydrate status detecting by PNA is changeable through cancer prognosis from primary to metastatic nodal site: A possible prognostic factor in patient with node-positive lung adenocarcinoma.
Carbohydrates antigens in cancer cells are considered to be important molecules, which may play a critical role for metastasis. To elucidate the prognostic relevance of the expression of peanut agglutinin (PNA) binding carbohydrates in patients with lung adenocarcinoma, we investigated the PNA binding carbohydrates immunohistochemically in both of primary tumors and involving nodal lesions. A total of 62 patients with node-positive primary lung adenocarcinoma, who had undergone complete resection and regional nodes dissection were subjected to this study. There were no significant correlations between PNA staining rates and clinicopathological variables. The survival rate of patients who had positive PNA staining in both of primary tumor and nodal lesion was significantly higher than those of patients in the other groups. Furthermore, the loss of the staining rate of PNA was an independent prognostic factor beside the lymphatic vessel invasion using multivariate analysis. The expression of PNA binding carbohydrates in tumor tissue and nodal lesion would be a novel significant prognostic factor for patients with node-positive lung adenocarcinomas.
