  • Title: [Vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) expression in superficial transitional cell bladder carcinoma].

    Journal: Ai Zheng; 2003 Mar; 22(3):307-9. PubMed ID: 12654193.
    Abstract:
    BACKGROUND & OBJECTIVE: Vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) can promote the proliferation of endothelial cell and angiogenesis. They are important materials in growth, invasion, and metastasis of tumor. There were few reports of their difference in single and multiple superficial transitional cell bladder carcinoma. Our objective was to study the expression of them in single and multiple superficial transitional cell bladder carcinoma and their clinical significance. METHODS: Immunohistochemical method was used to study the VEGF and bFGF expression in 60 cases of superficial transitional cell bladder carcinoma and in 10 cases of normal bladder tissue (as control). RESULTS: The expression levels of VEGF (55.6%), bFGF (50.0%), and coexpression level of VEGF and bFGF (50.0%) in the multiple superficial transitional cell bladder carcinoma were higher than that in single tumor. The recurrent rate in the patients with VEGF high expression (61.1%) was higher than that in the patients with VEGF low expression (16.7%). CONCLUSION: The expression levels of VEGF and bFGF were correlated with the biological behavior of superficial transitional cell bladder carcinoma.
