Visualized Clinical-Radiomics Model Based on Non-Contrast Computed Tomography for Predicting Efficacy of Surufatinib in Hepatic Metastases of Neuroendocrine Neoplasms.
Article in Cancer medicine, 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
backgroundHepatic metastatic neuroendocrine neoplasms (HM-NENs) have few treatment biomarkers and low survival rates. We created a clinical-radiomics fusion model based on non-contrast computed tomography (NCCT) to predict Surufatinib efficacy in HM-NENs. We presented it as a nomogram, meeting unmet requirements in precision medicine.
methodsThis retrospective study included 76 HM-NEN patients (131 hepatic metastases) treated with Surufatinib. Regions of interest (ROI) were manually segmented, and the best response to Surufatinib was decided based on Modified Response Evaluation Criteria in Solid Tumor (mRECIST). Radiomics features were extracted from the pretreatment NCCT. The Least Absolute Shrinkage and Selection Operator (LASSO) was used to select radiomics features and calculate a Radiomics score (Radscore). Multivariable logistic regression analysis was utilized to create the clinical-radiomics fusion model, which included clinical characteristics and Radscore and was displayed as a nomogram. The area under the receiver operating characteristic curve (ROC) was used to assess model performance, and internal validation was done using the bootstrap resampling approach.
resultsAfter multivariate logistic regression analysis, the Radscore, the diameter of hepatic metastasis, the number of hepatic metastases, and extrahepatic metastasis were included as predictors in the final model. The area under the curve (AUC) of the clinical-radiomics fusion model to predict the response of Surufatinib of HM-NENs was 0.926 (95% confidence interval [CI]: 0.881-0.971). The AUC verified by bootstrap was 0.926 (95% CI: 0.880-0.966), indicating a good performance of the fusion model.
conclusionThe clinical-radiomics fusion model can effectively identify patients with HM-NENs sensitive to Surufatinib therapy. The nomogram provides clinicians with a convenient and dependable tool for decision-making.
