Methods and materials

This retrospective dataset includes extensive clinical data, baseline multiphase CT imaging, segmentations, and radiomics features of 233 treatment-naive patients. Inclusion criteria: 1) unresectable HCC; 2) conventional TACE; 3) Child-Pugh Class A/B; 4) baseline contrast-enhanced CT. Exclusion criteria: 1) liver transplantation, resection, or ablation; 2) other neoplasms. Outcome measures included overall survival (OS), progression-free survival (PFS), and TACE response. Segmentation masks for various internal organs were generated using nnU-Net model, while HCC were manually segmented in Slicer 3D by experienced radiologists. Radiomic features were extracted using PyRadiomics, following the Imaging Biomarker Standardization Initiative.
