Recurrent TRAF7-mutated meningioma: Molecular evolution and therapeutic insights.
Article in SAGE open medical case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Meningiomas are the most common primary intracranial tumors, with TRAF7 mutations identified in ~25% of cases. These mutations, associated with NFκB pathway activation, are linked to higher recurrence rates than other low-grade-associated mutations. We report a 49-year-old Caucasian woman with recurrent TRAF7-mutated World Health Organization Grade 2 meningiomas. Initially diagnosed with World Health Organization Grade 1 meningiomas in 2015, her disease progressed to Grade 2 chordoid meningioma by 2021. Molecular profiling revealed a TRAF7 exon 20 (p.R653Q) mutation and PMS2 deletion. Multiple surgical resections, radiation, and systemic therapies, including lanreotide, bevacizumab, and pembrolizumab, were employed, with pembrolizumab showing a favorable response due to mismatch repair deficiency. This case highlights the molecular and histological evolution of TRAF7-mutated meningiomas and the potential of immunotherapy in recurrent cases. The absence of targeted therapies for TRAF7-positive tumors underscores the need for mutation-specific clinical trials.
