Molecular and Clinical Oncology, 2021 The aim of the present study was to investigate whether the degree of contrast enhancement on contrast-enhanced (CE)-CT can predict the prognosis of patients with hepatocellular carcinoma (HCC) treated with lenvatinib (LEN). A total of 67 consecutive patients with LEN-treated HCC were retrospectively analysed.
