Drug Response Testing and Repurposing Using Glioblastoma Organoid

"The intervention in this study involves utilizing glioblastoma organoids (GBOs) to perform an organoid-based drug sensitivity test (DST) and retrospectively comparing the results with clinical outcomes. Notably, no interventions will be applied to participants based on GBO-DST results; the study is limited to retrospective analysis.~The GBO-DST is conducted by performing a drug response assay with temozolomide to determine the half-maximal inhibitory concentration (IC50), which serves to classify GBOs as TMZ-sensitive or TMZ-resistant. This classification is further validated through GBO cell survival analysis."
