Clinical and preclinical insights into a novel MDM2::PDGFRA fusion in recurrent glioblastoma.
Article in NPJ precision oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Glioblastoma is an aggressive and treatment-refractory primary brain tumor with limited therapeutic options and high recurrence. The molecular heterogeneity of glioblastoma poses a significant challenge to therapeutic development, as targeted therapies have mostly failed in small-scale clinical trials, underscoring the need for comprehensive next-generation sequencing (NGS) characterization to identify mechanisms of resistance. In this study, we identify and functionally characterize a novel amplified fusion, MDM2 (exon 1)::PDGFRA (exon 8), mediating resistance to cetuximab in an EGFR-amplified glioblastoma. The fusion results in a truncated PDGFRA isoform, in vitro assays demonstrate that MDM2::PDGFRA acts as a constitutively active oncogenic driver with a distinct sensitivity profile to tyrosine kinase inhibitors. Analysis of a glioblastoma cohort indicates PDGFRA structural variants often co-occur with amplification and may serve as biomarkers. These findings highlight the importance of repeat NGS profiling in clinical management and provide a translational framework for identifying and targeting emergent fusion-driven alterations.
