Abstract:
Objective To investigate the relationship in clinical features of invasive pituitary adenoma patients and their aggressive,matrix metalloproteinase 9 (MMP-9),vascular endothelial growth factor (VEGF) expression and tumor invasiveness of pituitary adenomas.Methods 96 patients with pituitary adenoma were selected,46 cases of invasive pituitary adenomas,50 cases of non-invasive pituitary adenomas,MMP-9,VEGF expression were detected by immunohistochemical assay,their expression levels were analyzed with tumor invasiveness correlation.Results MMP-9,VEGF expression in invasive pituitary adenomas strongly positive rates were 54.35％,52.17％,the total positive rates were 89.13％,95.65％,which were significantly higher than the non-invasive pituitary adenomas MMP-9,VEGF strong positive expression rate of 16.00％,20.00％,the total positive rates were 44.00％,56.00％ (x2 =15.618,9.416,21.631,20.090,all P ＜ 0.05);MMP-9,VEGF for invasive pituitary volume under positive circumstances,the maximum diameter was significantly higher than non-invasive of the group (t =4.32,3.67,2.49,2.54,all P ＜ 0.05),and MMP-9,VEGF were under negative circumstances invasive and non-invasive pituitary adenoma group,the difference was not statistically significant(t =1.56,1.47,0.53,0.21,all P ＞ 0.05);By correlation analysis,invasive pituitary adenoma MMP-9 expression was positively correlated with VEGF levels (r =0.734,P ＜ 0.01).Conclusion Invasive pituitary adenomas of MMP-9 and VEGF expression increased,MMP-9 and VEGF can be used as auxiliary judge biological indicators of invasive pituitary adenomas.
