摘要
Objective: Vitronectin is an extracellular matrix protein, the synthesis of which by glioma cells correlates with tumor grade. The current study was designed to investigate the relationship between serum vitronectin levels and clinicopathological characteristics, diagnosis and prognosis in glioma patients. @@@ Methods: In a prospective observatory study, a total of 98 glioma patients, 98 healthy controls, 98 other non-glioma brain tumors, and 98 other non-tumor neurological diseases were recruited. Following univariate analyses, multivariate analyses were performed to explore the associations of serum vitronectin levels with survival and clinicopathological parameters. Receiver operating characteristic curve analysis was done to assess its diagnostic and prognostic predictive value. @@@ Results: Serum vitronectin levels were significantly elevated in glioma patients as compared with other groups. High Wealth Health Organization grade was independently associated with high vitronectin levels. Serum vitronectin levels could significantly distinguish glioma patients from other groups and discriminate high-grade glioma from low-grade glioma. Vitronectin levels markedly predicted 5-year progression and 5-year mortality. Moreover, serum vitronectin was identified as an independent predictor for 5-year overall survival and 5 year progression-free survival as well as 5-year mortality and 5-year progression. @@@ Conclusion: Serum vitronectin may be a promising diagnostic and prognostic biomarker that can be detected in the peripheral blood of patients with glioma.
