TFF2, a novel serum diagnostic biomarker for early pancreatic cancer.
Article in Frontiers in oncology, 2025. 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
Background: Early detection and intervention are critical for improving the prognosis of pancreatic cancer (PC), but effective screening tests remain unavailable. Methods: A retrospective analysis was conducted on 92 PC cases, 50 benign pancreatic disease cases, 92 periampullary adenocarcinoma cases, and 92 healthy controls from September 2020 to September 2024 at Handan Central Hospital. Serum levels of CA199 and CEA were measured, and their diagnostic performance was evaluated by the area under the receiver operating characteristic (ROC) curve (AUC). Additionally, publicly available cancer genome datasets were analyzed to identify specific serum biomarkers for early PC, and clinical serum samples were collected to validate their expression and diagnostic utility. Results: CA199 and CEA effectively differentiated PC from benign pancreatic diseases and normal controls. However, they demonstrated limited value for distinguishing PC and periampullary carcinoma, with AUC values of 0.571 and 0.604, respectively. Trefoil factor 2 (TFF2), a gene encoding exocrine protein, was found to be specifically upregulated in pancreatic intraepithelial neoplasia and PC, with no significant expression observed in benign pancreatic diseases, cholangiocarcinoma, or hepatocellular carcinoma. Importantly, serum TFF2 levels were significantly elevated in the PC group, with AUC values of 0.947 for distinguishing PC from normal controls and 0.856 for differentiating it from periampullary adenocarcinoma, outperforming CA199 and CEA. The combination of TFF2 enhanced accuracy of CA199 and CEA to discriminate PC from periampullary adenocarcinoma. Conclusions: Serum TFF2 is a promising test for early screening of PC and may enhance diagnostic performance when combined with CA199 and CEA.
