Abstract: Liver cancer is a major global health concern whose clinical treatment means are limited, facing a series of challenges such as high postoperative recurrence rates, high transplant failure rates and resistance to chemotherapy drugs, and the overall clinical benefit is unsatisfactory. In recent years, with the rapid development of immunotherapy, major breakthroughs have been achieved in the treatment of multiple malignant tumors. As a new biological immunotherapy agent, oncolytic virus (OV) kills tumors by highly selective infecting and lysing tumor cells, activating the body's immune response, improving the tumor microenvironment and other mechanisms, and numerous clinical studies have been carried out in the treatment of liver cancer. The preliminary data show an encouraging application prospects. Herein, this review systematically introduces the mechanism of action of OV while comprehensively summarizes the latest clinical research progress of OV in liver cancer, Particularly,we emphasize the innovative products of OV in the treatment of liver cancer and its research and development design strategy, as well as sorts out the combination therapy of OV, which will provide potential directions for the future treatment of liver cancer with OV.
