ObjectiveTo elucidate the mechanism of evolimus (EVR) and its application, efficacy and common adverse reactions in hepatocellular carcinoma (HCC) patients after liver transplantation.MethodRelevant literatures in recent years were searched through websites such as Wanfang, CNKI and PubMed, and the results were read, analyzed and summarized.ResultsCurrently, there are a wide variety of immunosuppressive agents for HCC patients after liver transplantation, and immunosuppressive treatment options are also diverse and there is no unified standard. Today is more widely used clinically used for transplantation immune inhibitors of calcineurin inhibitors (CNIs), but because of its renal toxicity and side effects and recurrence of HCC risk increases, CNIs in HCC patients after liver transplantation using gradually is restricted, and mammalian target of rapamycin (mTOR) inhibitors are valued, gradually into clinical immunosuppression after liver transplantation for treatment provides a new way of thinking. As an mTOR inhibitor, EVR is gradually being applied to HCC patients after liver transplantation.ConclusionAs an mTOR inhibitor only approved for use in HCC patients after liver transplantation in recent years, relevant literature studies have shown that EVR plays an important role in improving the success rate of transplantation, protecting renal function and inhibiting HCC recurrence.
