Objective To analyze and summarize advantages, disadvantages, and limitations of present imaging techniques in assessing efficacy of immunotherapy for patient with hepatocellular carcinoma in order to provide strong evidence for drug therapy evaluation and clinical decision-making for it. Method The relevant literatures about imaging evaluation of immunotherapy for hepatocellular carcinoma were collected to make a review, then analyze and summarize the value of different imaging techniques. Results The immunotherapy, characterized by the noninvasive, high specificity and good curative effect, had been playing an important role in the treatment of hepatocellular carcinoma in recent years. The imaging techniques currently used to assess the immunotherapy results of hepatocellular carinoma mainly included the CT, MRI, ultrasound, and nuclear medicine, which could be used to better evaluate the effectiveness of immunotherapy. It was very important for screening of the patients’ treatment options and judging of the survival and prognosis. The most of the evaluation indicators were based on the anatomic evaluation criteria and it had some certain limitations in evaluating the immunotherapy efficacy of patient with hepatocellular carcinoma. Conclusions As an emerging biological therapy, immunotherapy has gradually become a hotspot in diagnosis and treatment of hepatocellular carcinoma in future. Present imaging techniques and evaluation criteria have certain limitations. More multifunctional imaging indicators need to be improved and developed so as to provide strong evidence for drug therapy evaluation and clinical decision of patient with hepatocellular carcinoma.
