R. China. All patients were divided into the invasion group (n=39), and the non-invasion group (n=27) by assessment of preoperative MRI and intraoperative inspection. Survivin expression was determined by immunohistochemistry. Statistical analysis of survivin expression between the 2 sample groups was accomplished using the chi-square test.RESULTS: Survivin was expressed in 46 (69.7%) of the investigated pituitary adenomas. For invasive pituitary adenoma, survivin staining was positive in 35 (89.7%), only 11 (40.7%) specimens were positive in noninvasive tumors. The chi-square test demonstrated a statistically significant difference in survivin expression between invasive and noninvasive pituitary adenoma (x2=14.309, p=0.0002).CONCLUSION: Survivin was highly associated with invasive pituitary adenoma, it is likely to serve as a useful tool for confirmation of invasive pituitary adenoma and the gene could be an effective target for pituitary adenoma gene therapy.
