Preoperative Multifrequency MR Elastography for Stratifying Wnt/β-Catenin Pathway and Microvascular Invasion Phenotypes in Hepatocellular Carcinoma.
Article in Journal of magnetic resonance imaging : JMRI, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe Wnt/β-catenin signaling pathway and microvascular invasion (MVI) are associated with the prognosis of hepatocellular carcinoma (HCC). PURPOSE: To evaluate the Wnt/β-catenin pathway and MVI states using preoperative MR elastography (MRE). STUDY TYPE: Prospective. POPULATION: 210 participants with surgically confirmed HCC (179 men; mean age 59.6 ± 0.8 years) and preoperative MRI/MRE. FIELD STRENGTH/SEQUENCE: 1.5 T/3 T, single-shot spin-echo MRE, T2-weighted image, diffusion-weighted imaging, DIXON, and contrast-enhanced T1-weighted imaging using fat-suppressed gradient sequence. ASSESSMENT: Imaging features were assessed using major and ancillary features of Liver Imaging Reporting and Data System v2018, together with MRE-derived stiffness and viscosity. Glutamine synthetase, β-catenin, and MVI expression were evaluated in surgical specimens. Recurrence-free survival (RFS) was assessed in participants with available follow-up data. STATISTICAL TESTS: Multivariate logistic regression, Cox proportional hazards regression, receiver operating characteristic analysis, and Kaplan-Meier survival analysis with log-rank test were used. P-value < 0.05 was considered significant.
resultsMVI and Wnt/β-catenin pathway activation were found in 59 and 105 participants, respectively. Wnt/β-catenin pathway activation (hazard ratio [HR] = 0.405, 95% CI: 0.247-0.664) and MVI (HR = 1.737, 95% CI: 1.021-2.954) predicted postoperative recurrence. Elevated tumor stiffness (odds ratio [OR] = 1.582, 95% CI: 1.034-2.420), total bilirubin > 24 μmol/L (OR = 2.465, 95% CI: 1.154-5.267), smooth tumor margins (OR = 2.226, 95% CI: 1.157-4.283), and mosaic architecture (OR = 1.990, 95% CI: 1.029-3.851) were significantly associated with Wnt/β-catenin pathway activation. Decreased tumor stiffness (OR = 2.075, 95% CI: 1.095-3.937), non-smooth margin (OR = 8.246, 95% CI: 3.048-22.307), peritumoral enhancement (OR = 2.677, 95% CI: 1.081-6.630), incomplete or absent capsule enhancement (OR = 3.846, 95% CI: 1.680-8.800), and multiplicity (OR = 2.579, 95% CI: 1.036-6.420) were independent indicators of MVI. MVI-positive HCC with Wnt/β-catenin pathway silence, median RFS was only 6.33 months. Risk factors for this phenotype included decreased tumor stiffness, non-smooth tumor margins, incomplete or absent capsule enhancement, and corona enhancement. DATA
conclusionIntegrating tumor stiffness with morphological features may help preoperatively identifying HCC with poor postoperative outcomes. EVIDENCE LEVEL: 1. TECHNICAL EFFICACY: Stage 2.
