Dual-energy CT Biomarkers for Predicting Efficacy of TACE-LEN-ICIs in uHCC
This study developed a nomogram based on low-dose one-stop dual-energy and perfusion computed tomography (LD-DE&PCT) for predicting the efficacy of transcatheter arterial chemoembolization (TACE) combined with lenvatinib and immune checkpoint inhibitors (TACE-LEN-ICIs) in unresectable hepatocellular carcinoma (uHCC) patients. It identified tumor size, normalized iodine concentration in arterial phase (NIC-AP), and permeability surface area product (PS) as independent predictors, with the nomogram showing excellent performance (AUROC = 0.913). This non-invasive method can accurately predict response, aiding treatment decisions for uHCC patients.

Normalized Iodine Concentration (NIC-AP) showed the highest individual predictive value among single parameters.
Multivariate analysis confirmed tumor size, Normalized Iodine Concentration in Arterial Phase (NIC-AP), and Permeability Surface Area Product (PS) as independent predictors for the efficacy of TACE-LEN-ICIs. While NIC-AP demonstrated the strongest individual predictive performance, the combined nomogram integrating all three factors achieved a superior AUROC of 0.913.
Higher values of NIC-AP and PS in the non-response (NR) group compared to the objective response (ObR) group suggest increased microvessel density and vascular permeability within tumors, indicating more aggressive tumor biology and potentially reduced therapeutic delivery for TACE-LEN-ICIs. Implementing AI to identify and quantify these specific biomarkers from LD-DE&PCT scans offers a robust, non-invasive method for patient stratification, significantly enhancing prognostic capabilities for uHCC.
Translating Predictions to Treatment Decisions
Real-world application of the predictive nomogram can optimize therapeutic strategies for unresectable HCC.
Patient Response Prediction in Action
Case 1 (Objective Response): A 65-year-old uHCC patient with a tumor size of 42.4 mm, NIC-AP of 17.42%, and PS of 17.38 mL/min/100g. The nomogram would accurately predict an objective response to TACE-LEN-ICIs, guiding clinicians to proceed with this regimen with confidence.
Case 2 (Non-Response): In contrast, a 52-year-old uHCC patient presented with a larger tumor (100.5 mm), elevated NIC-AP (54.71%), and higher PS (36.57 mL/min/100g). For this patient, the nomogram would predict a non-response, indicating the need to consider alternative therapies like bevacizumab plus atezolizumab upfront, thereby potentially avoiding ineffective treatment courses and associated adverse effects.
This AI-driven prediction enables clinicians to personalize treatment, directing patients to the most effective regimen and improving overall prognosis and resource allocation in uHCC management.
