| Outline of Final Research Achievements |
Recently,research efforts in identifying prognostic molecular biomarkers for malignant glioma have intensified. Cysteine-rich protein 61(CYR61)is one of the CCN family of matricellular proteins that promotes cell growth and angiogenesis in cancers through its interaction with several integrins. In this study,we investigated the relationships among CYR61,O6-methylguanine-DNA methyltransferase(MGMT)expression,the tumor removal rate and prognosis in 46 glioblastoma patients treated at the Okayama University Hospital. CYR61 expression was positive in 31(67%)of these patients. The median progression-free survival(PFS)and overall survival(OS)times of patients with strong CYR61 expression was significantly shorter than those of patients with weak CYR61 expression. In a multivariate Cox analysis,CYR61 proved to be an independent prognostic factor for patient survival. It was concluded that CYR61 might emerge as a significant prognostic factor regarding the prognosis of glioblastoma patients.
