ABSTRACT
Objective:To evaluate radiofrequency ablation-assisted liver resection on early recurrence of hepatocellular carcinoma(HCC) with microvascular invasion (MVI).Methods:A total of 82 HCC patients from Jun 2015 to Jun 2020 were divided into assisted group ( n=41) and control group ( n=41) after local hepatectomy.And by pathology,both groups were further substratified into with or without MVI subgroups. Results:There was no statistically significant difference in the baseline data between two groups,nor there was difference in recurrence-free survival rate between the two groups ( χ 2=0.177, P=0.674). However, by subgroup analysis, the recurrence-free survival rate of ablation assisted group was higher than that of the simple local hepatectomy group among MVI positive patients ( χ 2=5.096, P = 0.024).Multivariate analysis showed that only tumor diameter ( HR=1.32, 95% CI: 1.02-1.72, P=0.036) was an independent risk factor for local recurrence at the incisal margin, while mode of operation ( HR=0.15 ,95% CI: 0.04-0.52 ,P=0.003) and MVI ( HR=8.65 ,95% CI: 2.19-34.19 ,P=0.002) were independent risk factors for intrahepatic distant metastasis. Conclusion:Local hepatectomy assisted by intraoperative radiofrequency ablation on hepatic cross section could effectively reduce the postoperative early recurrence rate for hepatocellular carcinoma patients with MVI.
