Abstract This retrospective study, conducted at Taichung Veterans General Hospital in Taiwan, employed Next-Generation Sequencing (NGS) technology to analyze genetic variations associated with survival in patients with glioblastoma multiforme (GBM). The study encompassed 30 newly diagnosed GBM patients, divided into two groups based on survival duration: long-term (over two years) and short-term (under two years). The findings are outlined below: Key Mutations: Significant mutations included CHEK2, IDH1, and TP53, along with variations in the TERT promoter and TP53 RNA splicing sites. Correlation Between Mutations and Survival: Contrary to Western data, TP53 mutations were more prevalent in the long-term survival group, suggesting that regional genetic differences may influence GBM prognosis. Therapeutic Effectiveness: The application of bevacizumab was significantly associated with improved survival rates, indicating its potential efficacy in treatment. The study highlights the critical role of personalized medicine in the treatment of GBM in Taiwan and points to the necessity of further research into the genetic characteristics and treatment responses of GBM patients in Taiwan and potentially other non-Western regions. These insights underline the importance of continuing to explore effective personalized treatment strategies and enhancing our understanding of genetic determinants in diverse populations. Moreover, the prevalence of certain mutations in Taiwanese patients, which differ from those commonly observed in Western populations, prompts a reevaluation of global treatment frameworks and suggests the potential for region-specific therapeutic protocols. The implication of these findings extends beyond immediate clinical applications, providing a foundation for future clinical trials and research into genetic markers that could dictate treatment choices. In conclusion, this study not only underscores the importance of individualized treatment plans based on genetic profiling but also highlights the variations in genetic mutations across different populations, which could have profound implications for the management of GBM worldwide. Further investigation into these disparities and their implications on treatment efficacy is essential for advancing GBM treatment and improving patient outcomes globally.
