ABSTRACT
Objective To compare the results of surgical resection with radiofrequency ablation in the treatment of primary hepatocellular carcinoma with type Ⅰ portal vein tumor thrombus.Methods The clinical data of 30 patients with primary hepatocellular carcinoma with type Ⅰ portal vein tumor thrombus treated between January 2006 and December 2009 were analyzed retrospectively.Patients were divided into two groups according to the treatment.Result The treatments were successfully carried out in the surgical resection group (n=15) and the radiofrequency ablation group (n =15).There was no perioperative death.Both surgical resection and radiofrequency ablation improved the overall survival and recurrence-free survival.The survival outcome of radiofrequency ablation was similar to surgical resection.Conclusion Both surgical resection and radiofrequency ablation were safe and effective for patients with primary hepatocellular carcinoma with type Ⅰ portal vein tumor thrombus and improved the overall survival and recurrence-free survival.
