Clinicopathological and Prognostic Implications of Epithelial-to-Mesenchymal Transition-Related Immunohistochemical Markers in Resectable Pancreatic Cancer: A Retrospective Longitudinal Study.
Article in Cancer reports (Hoboken, N.J.), 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
backgroundPancreatic ductal adenocarcinoma (PDAC) is the sixth leading cause of global cancer death. The process of epithelial-to-mesenchymal transition (EMT) is a key driver of early progression and metastasis in PDAC.
aimOur study aimed to explore the correlation between the expression of EMT markers and survival outcomes. METHODS AND
resultsWe conducted a retrospective longitudinal study on patients diagnosed with resectable PDAC between January 2005 and June 2019, with a 5-year follow-up for survival analysis. Immunohistochemical staining was performed to assess E-cadherin and vimentin expression. EMT was defined as the presence of high Vimentin (mesenchymal) expression combined with low E-cadherin (epithelial) expression. The study cohort included 135 patients with resectable PDAC, with 86 males (63.7%) and a mean age of 63.5 years (SD 10.1); most tumors were grade 2 (84, 64.6%). Cox regression analysis revealed that Vimentin expression (p = 0.005), positive margin (p = 0.008), and absence of metformin intake (p = 0.023) were independent predictors of poor OS. High Vimentin was associated with lower median OS (17.0 ± 4.4 vs. 25.8 ± 2.3 months, p = 0.037) and DFS (8.6 ± 1.2 vs. 13.0 ± 2.3 months, p = 0.014), compared to low Vimentin, and it was correlated with higher tumor grade (p = 0.028) and metastasis rate (p = 0.032). The poorest outcomes were observed when high Vimentin was coupled with low E-cadherin (median OS of 12.6 ± 4.7 vs. 24.5 ± 2.1 months, p = 0.038; median DFS of 9.5 ± 0.5 vs. 10.8 ± 2.1 months, p = 0.029), compared to the rest of the population.
conclusionOur findings showed that Vimentin overexpression and the EMT phenomenon are strongly associated with poor OS and DFS in resectable PDAC, underscoring their potential as prognostic biomarkers and therapeutic targets.
