Application of multimodal fusion technology in early recurrence prediction and pathological analysis of hepatocellular carcinoma.

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
backgroundEarly recurrence is an important factor affecting the prognosis of hepatocellular carcinoma (HCC), but its preoperative prediction remains challenging.
aimTo explore the value of a multimodal interpretable fusion model combining computed tomography (CT) habitat imaging (HI), radiomics, and clinical features in predicting early recurrence of HCC and analyze its correlation with pathological indicators.
methodsThe 191 HCC patients were categorized into early recurrence and non-early recurrence groups based on postoperative follow-up outcomes, and randomly divided into training and testing sets in a 7:3 ratio. Based on CT arterial phase and clinical data, the habitat model, radiomics model, clinical model, and fusion model were constructed and compared for their predictive ability in early recurrence of HCC. For the optimal model, SHapley Additive exPlanations (SHAP) analysis was performed to evaluate the contribution of different features in the model, and the correlation between HI and radiomics features with tumor microvascular invasion (MVI), Ki67 expression, GPC-3 expression, and pathological grading was analyzed.
resultsThe fusion model demonstrated the best performance in predicting early recurrence of HCC, achieving the area under the curve of 0.933 on the validation set. The decision curve analysis curve indicated that the fusion model yielded the highest clinical net benefit. SHAP analysis provided valuable insights into explaining the fusion model's prediction of early HCC recurrence. Correlation analysis revealed significant associations between certain radiomics and Habitat features and pathological indicators such as MVI and Ki-67 expression in HCC.
conclusionAn interpretable fusion model integrating clinical, radiomic, and habitat features can assist clinicians in identifying early postoperative recurrence of HCC, offering significant potential for prognosis prediction and clinical management.
