Currently,liver cancer is the fourth most common cause of cancer mortality *** overwhelming majority of liver cancers are hepatocellular carcinomas(HCC),developing on the background of chronic liver diseases,including chronic hepatitis B,chronic hepatitis C,and non-alcoholic steatohepatitis(1).Despite the recent progress in the treatment of HCC,it remains largely refractory,with a high recurrence rate even after therapeutic intervention(2).Numerous agents,including tyrosine-kinase inhibitors(TKIs),antibodies blocking the vascular endothelial growth factor(VEGF)/VEGF receptor(VEGFR)axis,and immune checkpoint inhibitors,are now available for the treatment of advanced stage HCC(3).However,their antitumor responses are still unsatisfactory.

Intrahepatic cholangiocarcinoma(iCCA)is a rare malignancy,constituting approximately 3-5%of hepatic tumors,with an increasing incidence in recent years(1).Early stage iCCA typically presents asymptomatically,often resulting in its detection at advanced *** resection remains the primary therapeutic approach for iCCA;however,a substantial proportion of patients are precluded from surgery due to disease progression,necessitating a reliance on pharmaceutical interventions(2).

Radiofrequency ablation (RFA) is commonly applied for the treatment of hepatocellular carcinoma (HCC) because of the facile procedure, and the safety and effectiveness for the treatment of this type of tumor. On the other hand, it is believed that HCC cells should spread predominantly through the blood flow of the portal vein, which could lead to the formation of intrahepatic micrometastases. Therefore, monitoring tumor response after the treatment is quite important and accurate assessment of treatment response is critical to obtain the most favorable outcome after the RFA. Indeed, several reports suggested that even small HCCs of ≤ 3 cm in diameter might carry intrahepatic micrometastases and/or microvascular invasion. From this point of view, for preventing local recurrences, RFA should be performed ablating a main tumor as well as its surrounding non-tumorous liver tissue where micrometastases and microvascular invasion might exist. Recent advancement of imaging modalities such as contrast-enhanced ultrasonic, computed tomography, and magnetic resonance imaging are playing an important role on assessing the therapeutic effects of RFA. The local recurrence rate tends to be low in HCC patients who were proven to have adequate ablation margin after RFA; namely, not only disappearance of vascular enhancement of main tumor, but also an adequate ablation margin. Therefore, contrast enhancement gives important findings for the diagnosis of recurrent HCCs on each imaging. However, hyperemia of non-tumorous liver surrounding the ablated lesion, which could be attributed to an inflammation after RFA, may well obscure the findings of local recurrence of HCCs after RFA. Therefore, we need to carefully address to these imaging findings given the fact that diagnostic difficulties of local recurrence of HCC. Here, we give an overview of the current status of the imaging assessment of HCC response to RFA.
