The clinical impact of EGFR alterations in elderly glioblastoma patients: results from a real-life cohort.
Article in Journal of neuro-oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
backgroundThe incidence of glioblastoma in the elderly population is increasing as the worldwide population ages. The differential and poorer survival in the elderly population compared to younger patients is partially explained. The present study aimed to investigate the clinical impact of epidermal growth factor receptor EGFR-altered glioblastoma in a real-life elderly glioblastoma population. PATIENTS AND
methodsA bicentric and retrospective study was conducted. Patients were 70 years or older and suffering from histomolecularly confirmed glioblastoma. Single nucleotide variants (SNV), amplification, or chromosome 7 polysomy were sought. The primary endpoint was the comparison of overall survival (OS) in patients with or without EGFR alteration. Secondary objectives were to determine other clinical parameters correlated with EGFR alteration status.
resultsSeventy-three patients were analyzed: 41.1% had at least one EGFR alteration. The presence of EGFR alteration did not impact overall survival: HR 0.97 [0.6-1.57], p = 0.9; the median overall survival was 6.5 months [5.3-9.3] in the EGFR-altered group versus 7 months [4.5-10] in the EGFR wild-type group, p = 0.75. In multivariate analysis, tumor resection was associated with a significant overall survival improvement: the median OS in the resected group (n = 20) was 11 months [95% CI 7.8-22] versus a median OS of 5.5 months [4.6-7.8] in the unresected group (n = 53), without correlation to EGFR alteration status.
conclusionIn the modern era of molecular characterization and improved treatment modalities, the presence of at least one EGFR alteration did not influence survival outcomes in an elderly population of glioblastoma patients.
