Abstract
ObjectiveTo investigate the value of sequential implications of transcathater arterial chemoembolization (TACE) and radiofrequency ablation (RFA) for postoperative recurrence of large hepatocellular carcinoma.
MethodsFrom January 2004 to December 2015, one hundred and thirteen cases undergoing liver cancer resection in Zhongshan City People’s Hospital were analyzed retrospectively. TACE was performed in 53 cases after operation (TACE group), TACE+RFA in 34 cases (TACE+RFA group), and 26 cases were treated with simple resection (simple resection group). The overall survival, postoperative 1-, 3-, 5-year survival rates, 1-, 2-, 3-year recurrence rates were used to evaluate the long-term effects of the three groups.
Results(1) The median survival time was 39.0, 49.0, 29.0 months in TACE group, TACE+RFA group and simple resection group, respectively. The median survival time of TACE+RFA group was the longest, and the simple resection group was the shortest (χ2=12.5, P=0.002). (2) The 1-, 3- and 5-year survival rates in TACE group were 86.8%, 62.2% and 34.0%, respectively; 82.3%, 55.8% and 41.1% in TACE+RFA group, while those in simple resection group were 76.9%, 34.6% and 19.2% respectively. The 3-, 5-year survival rates of the 3 groups were statistically significant, and the long-term survival rate was the highest in the TACE+RFA group (P<0.05). (3) The 1-, 2-, and 3-year recurrence rate was 15.1%, 33.9% and 62.2% in TACE group; 29.4%, 55.9% and 70.5% in TACE+RFA group; 23.1%, 42.3% and 80.7% in simple resection group, respectively. The 3-year recurrence rate in simple resection group was significantly higher than the other two groups, and all the annual recurrence rates were the lowest in TACE group after operation (P<0.05).
ConclusionsPostoperative TACE can prevent middle and long term recurrence of large liver carcinoma after operation. The sequential application of TACE combined with RFA can significantly improve the prognosis of large hepatocellular carcinoma with postoperative recurrence.
