Prognostic Impact of CD133 mRNA Expression in 48 Glioblastoma Patients Treated with Concomitant Radiochemotherapy: A Prospective Patient Cohort at a Single Institution

摘要

Background Cancer stem cells are thought to represent the population of tumorigenic cells responsible for tumor development. The CD133 antigen has been described as a putative stem cell marker in malignant brain tumor that could identify such a tumorigenic population in a subset of glioblastoma. To date, the correlation between CD133 expression in primary glioblastoma and patient prognosis is not clearly established. To address this question we investigated the relationship between CD133 mRNA expression and patient outcome in a glioblastoma patient cohort.
