Abstract

We describe the landscape of somatic genomic alterations based on multidimensional and comprehensive characterization of more than 500 glioblastoma tumors (GBMs). We identify several novel mutated genes as well as complex rearrangements of signature receptors, including EGFR and PDGFRA. TERT promoter mutations are shown to correlate with elevated mRNA expression, supporting a role in telomerase reactivation. Correlative analyses confirm that the survival advantage of the proneural subtype is conferred by the G-CIMP phenotype, and MGMT DNA methylation may be a predictive biomarker for treatment response only in classical subtype GBM. Integrative analysis of genomic and proteomic profiles challenges the notion of therapeutic inhibition of a pathway as an alternative to inhibition of the target itself. These data will facilitate the discovery of therapeutic and diagnostic target candidates, the validation of research and clinical observations and the generation of unanticipated hypotheses that can advance our molecular understanding of this lethal cancer.

  • IDH mutant gliomas share the proneural transcriptional program characteristic of PDGFRA-amplified tumors.

    “Nonetheless, IDH mutant gliomas strongly express PDGFRA (Fig. 2b), and share the proneural transcriptional program characteristic of PDGFRA-amplified tumors23,24.”

    From Insulator dysfunction and oncogene activation in IDH mutant gliomas (2016) · cites this paper as [23]

    In Results, under “Molecular subclasses defined by global mRNA expression and DNA Methylation” (page unavailable), the paper describes G-CIMP and non-G-CIMP proneural glioblastomas as transcriptomically similar and associates PDGFRA amplification with the non-G-CIMP proneural subgroup. It reports that all IDH1-mutant cases had the G-CIMP pattern. These findings support the shared proneural program in the glioblastomas studied, but do not establish it for IDH-mutant gliomas more broadly. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • PDGFRA amplification and gain-of-function mutations are rare in IDH mutant tumors.

    “Although PDGFRA is a frequent target of genomic amplification and gain-of-function mutations in glioblastoma (15%), such alterations are rare in IDH mutant tumors23,24.”

    From Insulator dysfunction and oncogene activation in IDH mutant gliomas (2016) · cites this paper as [23]

    The Results section on molecular subclasses associates PDGFRA amplification with the non-G-CIMP+ proneural subgroup and describes concurrent amplification in a group predominantly lacking IDH1 mutations. The Results section on somatic alterations also finds IDH1 mutations more prevalent in GBM without RTK alterations. These findings support the direction of the amplification claim in GBM, but the cited passages do not establish that PDGFRA gain-of-function mutations are rare in IDH-mutant tumors. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • The promise of precision oncology has yet to be realized in GBM despite identification of relevant molecular targets.

    “The promise of precision oncology has yet to be realized in GBM despite identification of relevant molecular targets (34).”

    From Preclinical Modeling of Navtemadlin Pharmacokinetics, Pharmacodynamics, and Efficacy in IDH–Wild-type Glioblastoma (2025) · cites this paper as [34]

    The Introduction identifies biologically relevant GBM pathways and says that functional redundancy permits adaptation to targeted molecular treatments. It describes effective therapies as a future goal, but does not directly assess whether precision oncology’s promise has been realized in GBM. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • Deregulation of the core p53 pathway occurs in 43% of GBM cases.

    “Deregulation of the core p53 pathway occurs in 43% of cases due to: (i) TP53 gene mutation or homozygous deletion in 27.9% of cases, (ii) focal MDM2 amplification in 8–9% of cases, and (iii) focal MDM4 amplification in 7–9% of cases.”

    From Preclinical Efficacy of the MDM2 Inhibitor RG7112 in <i>MDM2</i> -Amplified and <i>TP53</i> Wild-type Glioblastomas (2016) · cites this paper as [4]

    In Results, ‘The landscape of somatic alterations in glioblastoma’ (page unavailable), the paper reports TP53 mutation/deletion in 27.9% of tumors and MDM1/2/4 amplification in 15.1%. Those figures total approximately 43%, but the paper reports 85.3% dysregulation of the p53 pathway when CDKN2A deletion is included. It does not give the cited separate 8–9% amplification rates for MDM2 and MDM4. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • TP53 gene mutation or homozygous deletion occurs in 27.9% of GBM cases.

    “Deregulation of the core p53 pathway occurs in 43% of cases due to: (i) TP53 gene mutation or homozygous deletion in 27.9% of cases, (ii) focal MDM2 amplification in 8–9% of cases, and (iii) focal MDM4 amplification in 7–9% of cases.”

    From Preclinical Efficacy of the MDM2 Inhibitor RG7112 in <i>MDM2</i> -Amplified and <i>TP53</i> Wild-type Glioblastomas (2016) · cites this paper as [4]

    In Results, ‘The landscape of somatic alterations in glioblastoma’ (page not provided), the paper reports TP53 mutation or deletion in 27.9% of tumors. It does not specify that the deletions counted in that figure were homozygous, so the claim’s narrower deletion type is not established by our copy. (LLM, conf=0.82)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
