A Proteomics and Metabolomics-based Approach to Biomarkers Identification for the Early Diagnosis of Cholangiocarcinoma in a Hamster Model: A Preliminary Study.
Article in Asian Pacific journal of cancer prevention : APJCP, 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
backgroundCholangiocarcinoma (CCA) poses a significant public health challenge, particularly in northeastern Thailand, where its prevalence is the highest worldwide. Early detection and effective treatment remain challenging due to the absence of sensitive and specific biomarkers. This study aimed to identify novel plasma proteins and metabolites as potential biomarkers for the early diagnosis of CCA.
methodsPlasma samples from hamsters with Opisthorchis viverrini (OV)/dimethylnitrosamine (DMN)-induced CCA and healthy controls (n=3 per group) were analyzed by LC-MS/MS-based proteomics and metabolomics.
resultsMore than 5,000 proteins were identified, including 572 unique to CCA hamsters at week 12. At weeks 8 and 12, 412 and 545 proteins, respectively, were functionally linked to cell proliferation, signal transduction, and metabolic regulation. Metabolomic analysis revealed 273 metabolites, with 59-including cystathionine, putrescine, UDP-N-acetyl-glucosamine, and FMN, upregulated in the CCA group.
conclusionThis study provides preliminary insights into candidate biomarkers for the early detection of CCA. These findings are intended to generate hypotheses for future research. Larger studies, including human validation cohorts, are warranted to confirm their clinical applicability.
