Preoperative CT-based radiomics prediction of tertiary lymphoid structures and prognostic integration with pathological microvascular invasion in resectable hepatocellular carcinoma: a multicenter study.
OBJECTIVES Tertiary lymphoid structures (TLS) reflect the tumor immune microenvironment and may provide prognostic information in hepatocellular carcinoma (HCC), but assessment requires pathology. This study aimed to develop and externally validate a CT radiomics-based machine-learning model for preoperative prediction...
