['The prognosis for gliomas is still dismal when treated with traditional approaches. Molecular targeted therapy has become a\xa0trend in treating tumors, including gliomas. However, molecular characteristics vary among different kinds of tumors and ethnic groups.', 'The aim of the research was to study the expression characteristics of key components in the EGFR pathway of gliomas in order to contribute new data for the molecular targeted treatment of gliomas.', 'EGFR, KRAS, BRAF, PI3K, phospho-EGFR and Ki67 expression were detected with immunohistochemistry in 82 glioma specimens.', "The expression of EGFR was positively correlated with the patients' age. There were no significant differences in clinicopathological characteristics between gliomas with and without phospho-EGFR expression. EGFR overexpression was significantly correlated with phospho-EGFR expression. In gliomas with EGFR activation, overexpressions of EGFR, BRAF and PI3K were significantly correlated with proliferation. However, in gliomas without phospho-EGFR expression, only BRAF overexpression was significantly related to the proliferation of tumor cells."] Does bRAF overexpression induce rampant glioma proliferation independent of phospho-EGFR expression?
