KLF11 Expression Predicts Poor Prognosis in Glioma Patients
PURPOSE: Glioma is a primary intracranial malignant tumor with high recurrence and mortality rates. It is very important to study the prognostic factors. KLF11 can function as an oncogene or a tumor suppressor, depending on the tumor and tissue types and the cancer stage. In this study, we aimed to...

Sumario: | PURPOSE: Glioma is a primary intracranial malignant tumor with high recurrence and mortality rates. It is very important to study the prognostic factors. KLF11 can function as an oncogene or a tumor suppressor, depending on the tumor and tissue types and the cancer stage. In this study, we aimed to determine whether KLF11 expression is related to the overall survival of glioma patients. PATIENTS AND METHODS: We investigated KLF11 expression in 116 glioma patients with different grades using Western blot and immunohistochemistry assay. We analyzed the patients with different glioma grades and KLF11 expression levels by Kaplan–Meier survival curves. Independent prognostic factors for poor overall survival were identified by univariate and multivariate analyses. RESULTS: There were 37 patients in KLF11 low expression group and 79 patients in high expression group. There was no difference in gender, age, tumor diameter or tumor location between two groups. The patients in KLF11 high expression group had higher ECOG score (P =0.025) and higher WHO grades (P =0.029). Western blot and immunohistochemistry assay showed KLF11 expression was significantly upregulated in glioma groups compared with normal brain tissues group (P < 0.05), and the expression in grades III–IV was significantly higher than those in grades I–II (P < 0.05). Kaplan–Meier survival curve analysis showed high KLF11 expression tended to reduce the overall survival (P < 0.05). After univariate and multivariate analyses, KLF11 expression (P =0.003) and age (P =0.007) were independent prognostic factors for poor survival in glioma patients. CONCLUSION: KLF11 expression was increased in glioma tissues, and high KLF11 expression was associated with poor prognosis. KLF11 expression was an independent prognostic factor for poor survival in glioma patients. KLF11 may serve as a novel prognostic marker for gliomas and as a novel treatment target. |
