CD274 and hepatocellular carcinoma: suggest that a radiomics model based on multisequence MRI has the potential to predict the preoperative expression of PD-1 and PD-L1 in HCC, which could become an imaging biomarker for immune checkpoint inhibitor (ICI)-based treatment (15).However, to our knowledge, no study before has investigated whether the contrast-enhanced CT-based radiomics feature can be used to predict the PD-1 expression status and further illustrate its prognostic value of HCC.
