Anaplastic meningioma in a 6-year-old with somatic YAP1::MAML2 fusion and multiple endocrine neoplasia type 4 (MEN4) syndrome.
Article in Cancer genetics, 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
Meningiomas are the most common primary brain tumors in adults but much less frequent in children. Many subtypes exist, including anaplastic (malignant) meningioma, which accounts for less than 20% of pediatric tumors. Meningiomas can arise in association with cancer predisposition syndromes due to germline variants in genes such as NF2, MEN1 and SMARCE1. This report describes a 6-year-old boy diagnosed with anaplastic meningioma who was treated with surgery and focal radiation therapy. The family consented to participate in the Texas KidsCanSeq clinical genomics study. Analysis of germline and tumor samples detected a single germline finding of a CDKN1B pathogenic frameshift variant associated with Multiple Endocrine Neoplasia Type 4 (MEN4) without somatic loss of the other allele. Tumor analysis revealed a YAP1::MAML2 fusion, which has been previously reported in pediatric meningiomas not associated with NF2. YAP1::MAML2 fusion is a known driver for development of meningioma, but the role of the germline CDKN1B variant in the absence of a tumor second hit is unclear. This case highlights the importance of performing combined tumor and germline molecular genetic analysis of rare tumors to help clarify the risk of development of cancer in patients with rare cancer predisposition syndromes.
