Abstract
En 中文
Gliomas, and glioblastoma in particular, remain difficult to model because molecular heterogeneity, diffuse invasion, blood–brain and blood–tumour barrier effects, immune suppression and repeated therapeutic escape converge in the same disease. Two-dimensional cultures, glioma stem cell (GSC) systems, acute tumour slices and animal models remain indispensable for mechanistic research, pharmacology and in vivo validation. Glioma organoids are complementary research platforms, not components of routine diagnostic or treatment procedures. This review links model construction, microenvironmental validation, treatment perturbation and evidence-graded interpretation. We compare patient-derived glioma organoids, GSC-derived organoids, brain organoid–glioma co-cultures, genetically engineered brain tumour organoids, and vascular-associated, immune-cell-containing and chip-based platforms. We distinguish phenotypic resemblance from physiological fidelity, tumour-intrinsic drug sensitivity from delivery competence, and proof-of-concept activity from demonstrated clinical utility. We also examine temozolomide resistance, radiotherapy, targeted and combination therapy, antiangiogenic treatment, tumour-treating fields, immune-cell therapy, oncolytic viruses, multi-omic quality control and prospective validation. Organoids should not substitute for animal models or clinical trials. Their most defensible role is to provide a patient-derived functional layer between mechanism, regimen ranking and molecular tumour-board interpretation, with claims limited by assay reproducibility, clinically achievable exposure and outcome linkage.
