Establishment and genomic characterization of patient-derived organoids from gastric-type cervical adenocarcinoma.
Article in Journal of gynecologic oncology, 2026. 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
objectiveGastric-type cervical adenocarcinoma (GAS) is a highly lethal subtype of cervical cancer with poor prognosis and limited treatment options, accounting for approximately 20% of cervical adenocarcinomas in Japan. Owing to its rarity, appropriate research models for GAS are lacking, which has limited our understanding of its molecular biology. In this study, we aimed to establish and characterize patient-derived GAS organoids as a novel research tool to address this critical gap.
methodsFollowing a standard organoid culture protocol with Matrigel embedding, we successfully established stable GAS organoids from fresh tumor tissue obtained by biopsy from GAS patients. Histopathological and genomic analyses were conducted to evaluate the morphological and genetic fidelity of the organoids in comparison to the parental tumors.
resultsThe established GAS organoids recapitulated key morphological and genetic characteristics of the parental tumors. The genomic analysis revealed that the organoids retained copy number variation profiles indicative of a tumor survival genotype. Notably, these changes were observed between organoids derived from the same patient at a different time point, suggesting that organoids could reflect temporal tumor heterogeneity present in the parental tumor.
conclusionTo the best of our knowledge, these organoids represent one of the first cell-based research resources established from this subtype. They could help advance our understanding of this aggressive disease and offer a potential basis for future molecular and translational research.
