| Summary | OBJECTIVE:Glioblastoma (GBM) relapses locally or in a disseminated pattern, and is highly resistant to chemo-radiotherapy. Although dissemination is associated with poor prognosis for GBM patients, the clinico-pathological factors that promote dissemination have not been elucidated. Glypican-1 (GPC-1) is a heparin sulfate proteoglycan that is attached to the extracytoplasmic surface of the cell membrane and regulates cell motility. The aim of this study was to determine whether GPC-1 expression correlated with GBM dissemination and patient prognosis.METHODS:GPC-1 expression was examined by immunohistochemistry in 53 patients with GBM who received radiotherapy and temozolomide (TMZ) treatment. We assessed the relationship between dissemination and clinico-pathological factors, including GPC-1 expression. Additionally, we evaluated the relationship between GPC-1 expression and overall survival (OS) by uni- and multivariate analyses of a range of clinico-pathological factors, including age, Karnofsky Performance Status (KPS), extent of resection, and O6-methylguanine-DNA methyltransferase (MGMT) status.RESULTS:Logistic regression analysis revealed that GPC-1 expression correlated with dissemination (P = 0.0116). Log-rank tests revealed that age, KPS, extent of resection, MGMT status, dissemination (P = 0.0008) and GPC-1 expression (P = 0.0011) were significantly correlated with OS. Multivariate analysis indicated that age, MGMT status, and GPC-1 expression were significantly correlated with OS. GPC-1 expression had the highest hazard ratio (2.392) among all regressors.CONCLUSIONS:GPC-1 expression significantly correlated with OS in GBM patients who received radiotherapy and TMZ treatment. GPC-1 expression can help predict the occurrence of dissemination and shorter OS in GBM patients. |
