GATA6 Amplification Is Associated With Improved Survival in TP53-Mutated Unresectable Pancreatic Cancer.
Article in Pancreas, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectivesGATA6 expression is recognized as a favorable prognostic marker of pancreatic cancer, whereas TP53 is a poor prognostic marker. We evaluated treatment outcomes by genetic alterations in TP53 and GATA6 to determine the prognostic and predictive impact of co-alterations. MATERIALS AND
methodsA single institution retrospective analysis was performed on patients diagnosed with pancreatic ductal adenocarcinoma between 2014 and 2023. TP53 genotype and GATA6 amplification status were included in an analysis of overall survival (OS) and progression-free survival (PFS). Previously published patient-derived organoids were used to investigate correlation between genetic status and drug sensitivity.
resultsPatients with TP53 mutations had worse OS compared with the wild-type TP53 population. Patients with GATA6 amplification had better OS and a trend toward better PFS than the nonamplified population. Among patients with a TP53 mutation, patients with GATA6 co-alteration had longer OS compared with those who were not GATA6 amplified. In contrast, among patients who were TP53 wild-type, the presence or absence of a GATA6 amplification did not impact OS or PFS. GATA6 genotype was not associated chemotherapy drug response in an organoid pharmacotyping model.
conclusionsWe found that GATA6 amplification appeared to attenuate poor prognosis observed in TP53-mutant patients regardless of the type of standard chemotherapy received, suggesting the GATA6 amplification is a prognostic biomarker but not a predictive biomarker of standard-of-care chemotherapy.
