Objective:The aim of the study was to analyze the tumor recurrence factors in patients of primary hepatocellular carcinoma (PHC) with postoperative transcatheter arterial chemoembolization (TACE).Methods:A total of 121 cases of PHC by TACE after 1-2 months of surgery was retrospectively analyzed,followed up and analyzed the free survival time and the factors related to tumor-free survival.Results:In all 121 cases,1-,2-,and 3-year tumor-free survival rates were 72.73%,46.21% and 28.93%,respectively.Gender,age,HBV infection,tumor size,capsule is complete,degree of differentiation and the presence of vascular thrombosis were put into the COX proportional hazards model of survival time to select the influential variables.In the clinical data of all variables entering COX proportional hazards model,tumor size,tumor differentiation and the presence of vascular thrombosis were statistically significant contributions to the model.In the tumor diameter less than or equal 10 cm [P=0.040,Exp (B)=2.210],vascular thrombosis [P=0.039,Exp (B)=2.922] and the lower degree of tumor differentiation [P=0.035,Exp (B)=3.038],the risk of tumor recent recurrence increased.Conclusion:Tumor size,differentiation,and the presence of vascular thrombosis are the independent risk factors affecting the prognosis of PHC after TACE.
