Abstract    Portal vein tumor thrombus has a high incidence rate, and these patients have short survival time，so it is a difficult point in the treatment of the hepatocellular carcinoma. Radiofrequency ablation is an important minimally invasive technique for the treatment of small hepatocellular carcinoma，and it can benefit HCC patients with portal vein tumor thrombus under certain condition，but the recurrence and metastasis can easily happen after the monotherapy of radiofrequency ablation. Radiofrequency ablation combined with other treatments can effectively reduce the recurrence rate and prolong the long-term survival rate.
