The review emphasizes that neoplasms of the central nervous system are a highly heterogeneous group of malignant tumors affecting both pediatric and adult populations. They span a broad spectrum of histological subtypes and biological behaviors, which means therapeutic strategies must be tailored to tumor type and individual patient characteristics. Standard treatment typically combines surgical resection, radiotherapy, chemotherapy and emerging targeted therapies, yet the efficacy of these interventions varies considerably, and long-term remission and survival outcomes remain difficult to achieve.

According to the authors, resistance is multifactorial. Substantial contributions come from the blood-brain barrier, intratumoral heterogeneity and the tumor microenvironment. Together these factors form a complex, adaptive network that enables tumor survival and proliferation even under aggressive treatment regimens. The review highlights how the interplay among cellular plasticity, vascular and microenvironmental adaptations, and immune evasion contributes to therapeutic failure and tumor recurrence.

An important caveat runs through the analysis: mechanistic evidence is unevenly distributed across CNS malignancies. The evidence synthesized in the review is derived primarily from glioblastoma, with additional studies in medulloblastoma and atypical teratoid rhabdoid tumor. This means the picture of resistance built from these tumor types may not generalize uniformly to every CNS neoplasm, and the authors frame their synthesis accordingly rather than as a uniform account of all brain tumors.

The authors argue that a better understanding of these interlocking mechanisms may facilitate the development of more effective and personalized therapeutic strategies for CNS tumors. As a review article, the work consolidates existing findings rather than presenting new experimental data, and its conclusions reflect the state of the current literature on glioblastoma, medulloblastoma and atypical teratoid rhabdoid tumor.
