1. Evaluating the impact of IDH1 gene mutation and MGMT gene methylation on overall survival time in patients with glioblastoma
Main Article Content
Abstract
Mutation of the IDH1 gene (IDH1-m) and methylation of the MGMT gene (Methyl-MGMT) are molecular genetic markers that play a crucial role in the prognosis of patients with glioblastoma. A cross-sectional, retrospective study was conducted on 129 patients with glioblastoma who underwent tumor resection at Viet Duc University Hospital and Hanoi Medical University Hospital from 2017 to 2021. The results of the study showed that age < 65 (p = 0.003), IDH1-m (p = 0.036), and Methyl-MGMT (p = 0.043) are independent prognostic factors for overall survival (OS). OS in the Methyl-MGMT & IDH1-m group (median 20.5 months) was significantly higher compared to the Methyl-MGMT or IDH1-m group (median 9.6 months) and the UnMethyl-MGMT & IDH1-wt group (median 5.8 months) with p = 0.007.
