Somatic Mutations of Thymic Epithelial Tumors Identified in the Prospective THYMOGENE Trial.
Article in Thoracic cancer, 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 molecular landscape of thymic epithelial tumors has been partially elucidated. GTF2I mutation drives the pathogenesis in approximately 50% of tumors; however, the key molecular aberrations in the other cases remain unclear.
methodsWe designed a panel including the most frequently mutated genes in thymic epithelial tumors and sequenced tumor and normal DNA from 70 patients prospectively accrued at a single institution in the Thymogene trial. Moreover, 19 neoplastic samples were dissociated to isolate tumor cells using flow cytometry.
resultsGTF2I mutations were the most common, being present in 41% of patients. GTF2I mutations were prevalent in type A and AB thymomas, in Stage I-II tumors, and in patients without myasthenia gravis. The unique pattern of mutually exclusive and co-occurring mutations suggests a distinct pathogenesis for thymomas with and without GTF2I mutation. In 39% of patients, no mutations were found in the 77 genes evaluated. The absence of epithelial cells in some dissociated tumors highlights the challenge of identifying mutations in a subset of thymic epithelial tumors that lack the GTF2I mutation. Mutational signatures, including COSMIC 1, 19, and 25, were enriched, possibly linked to 5'-methylcytosine deamination and the effects of chemotherapy.
conclusionsGTF2I mutations drive the growth of a significant portion of thymic epithelial tumors, often in conjunction with other gene mutations. Somatic mutations are not commonly found in many GTF2I wild-type tumors, where the underlying genomic abnormalities remain elusive, even when using a dedicated tool for sequencing thymic epithelial tumors.
