Abstract:
Objective:To investigate the risk factors for recurrence of early and late stage hepatocellular carcinoma after receiving hepatic artery embolization combined with radiofrequency ablation therapy.Methods:246 cases with hepatocellular carcinoma who underwent hepatic artery embolization combined with radiofrequency ablation in Beijing You'an Hospital Affiliated to Capital Medical University from January 2006 to January 2011 were selected. Clinical and follow-up data were collected. Univariate Cox analyses was used to determine the factors influencing recurrence of early and late stage HCC after hepatic artery embolization combined with radiofrequencies ablation. Multivariate Cox regression analysis was used to determine the independent factors.Results:246 case with hepatocellular carcinoma were treated with hepatic artery embolization combined with radiofrequency ablation, with median follow-up time of 99 months. A total of 179 cases had recurrence and 67 cases had no recurrence. Considering 24 months as the limit, 95 cases had early recurrence and 84 cases had late recurrence. The 1-, 2-, 3-, 5-, and 10-year recurrence rates were 21.3%, 39.0%, 53.0%, 67.3%, and 77.6%, respectively. Multivariate Cox regression analysis showed that the maximum tumor diameter ( HR = 2.183, 95% CI: 1.414-3.369, P < 0.01) and tumor number ( HR = 1.681, 95% CI: 1.110-2.545, P < 0.05) were independent factor influencing recurrence of early stage HCC after hepatic artery embolization combined with radiofrequency ablation. Liver cirrhosis ( HR = 0.421, 95% CI: 0.272-0.651, P < 0.01) was an independent factor influencing recurrence of late stage HCC after hepatic artery embolization combined with radiofrequency ablation. Conclusion:Tumor diameter and number are independent factors influencing recurrence of early stage HCC, while liver cirrhosis is an independent factor influencing recurrence of late stage HCC after hepatic artery embolization combined with radiofrequency ablation therapy.
