Objective We studied the expression of VEGF and its receptor,FLK- 1,in neuroblastoma and its relation to clinical features.Methods With the help of antigen repairing,immunohistochemical analysis using antibody against VEGF,FLK- 1 was carried out on speciments of 52 cases of neuroblastoma.Results There were 36 cases of VEGF and 34 cases of FLK- 1 positive expression,the expression of them were nearly consistent.The positive rate of VEGF and FLK- 1 were higher in metastatic tumors(28/34,26/34)than in non- metastastic tumors and had statistical significance(respectively P<0.01,P<0.05).The expression of VEGF in UH tumors was higher than in FH tumors,and statistical value is significant(P<0.05).Conclusion VEGF is a vital angiogenic factor,and may play an improtant role in the progression and metastasis of neuroblastoma.Its expression and function correlates well to FLK- 1,and may aid in predicting patients at risk of metastasis.
