Prognostic role of claudin-18.2 in intrahepatic cholangiocarcinoma.
Article in Virchows Archiv : an international journal of pathology, 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
Claudins are key components of tight junctions, essential for maintaining cellular adhesion, regulating intercellular molecule transport, and preserving cell polarity. Altered claudin expression can lead to tight junction dysfunction, potentially disrupting signaling pathways and contributing to the development of epithelial cancers. This study aims to explore the understudied role of CLDN18.2 in intrahepatic cholangiocarcinoma and its relationship with clinical outcomes. We analyzed tissue samples from 182 patients who underwent curative surgery for intrahepatic cholangiocarcinoma. Our research examined the relationship between CLDN18.2 expression and various clinical factors, including patient characteristics, pathological findings, and survival metrics such as overall survival (OS), disease-free survival (DFS), metastasis-free survival (MeFS), and local recurrence-free survival (LRFS). Overexpression of CLDN18.2 showed significant associations with R1 resection (p = 0.032) and advanced T stage (p = 0.043). Univariate analysis revealed that high CLDN18.2 expression was correlated with poorer OS (p = 0.0002), DFS (p < 0.0001), LRFS (p < 0.0001), and MeFS (p < 0.0001). Multivariate analysis further confirmed that high CLDN18.2 expression was independently associated with worse OS (p = 0.015), DFS (p < 0.001), LRFS (p < 0.001), and MeFS (p < 0.001). Overexpression of CLDN18.2 was associated with unfavorable clinical prognosis and adverse pathological features in intrahepatic cholangiocarcinoma. These findings suggest that CLDN18.2 could serve as a potential prognostic biomarker for intrahepatic cholangiocarcinoma.
