Clinical, molecular, and radiological predictors of prognosis in newly diagnosed astrocytoma, IDH-mutant, WHO grade 4.
Article in Neuro-oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundAstrocytoma, isocitrate dehydrogenase-mutant, WHO grade 4 (Astro4), is a new tumor type in the 2021 WHO classification of central nervous system tumors that has been poorly characterized in the literature. This study evaluates predictors of prognosis in a large cohort of newly diagnosed Astro4.
methodsWe retrospectively identified 128 consecutive adult patients who presented with an initial diagnosis of Astro4 at Dana-Farber Cancer Institute and Massachusetts General Hospital between 2010 and 2021. Clinical, molecular, and radiological characteristics were recorded, and their associations with overall survival (OS) and progression-free survival (PFS) were measured by log-rank test and Cox proportional hazards model.
resultsThe median age at diagnosis was 37.1 years, and 61.7% were men. The median OS was 5.9 years (95% confidence interval, 4.4-7.3), while the median PFS was 2.7 years (1.8 -3.6). Age ≥ 50 and homozygous CDKN2A/B deletion were independent negative prognosticators of OS on univariate and multivariate analyses (hazard ratio [HR], 2.21 [1.16-4.21], P = .019; HR, 2.61 [1.27-5.38], P = .013). Maximal resection of enhancing disease was associated with longer PFS on univariate and multivariate analyses (HR, 0.48 [0.26-0.87], P = .019). There were no significant differences in OS or PFS based on MGMT promoter methylation status, T2/FLAIR extent of resection, T2/FLAIR mismatch, radiological pseudoprogression, or enhancement on the pre-operative scan.
conclusionsOur study comprehensively characterizes a large cohort of newly diagnosed patients with Astro4, emphasizing the prognostic value of CDKN2A/B deletion, age, and the extent of resection of enhancing disease in these patients.
