Barcelona Clinic Liver Cancer Stage B Hepatocellular Carcinoma: Transarterial Chemoembolization or Hepatic Resection?

According to the Barcelona Clinic Liver Cancer (BCLC) guidelines, transarterial chemoembolization (TACE) is recommended for BCLC stage B hepatocellular carcinoma (HCC). However, an investigation of the use of resection for BCLC stage B is needed. Therefore, we compared the efficacy and safety of hepatic resection (HR) with that of TACE in treating intermediate HCC. We retrospectively enrolled 923 patients with BCLC stage B HCC who underwent TACE (490 cases) or HR (433 cases). The baseline characteristics, postoperative recoveries, and long-term overall survival rates of the patients in these 2 groups were compared. Subgroup analyses and comparisons were also performed between the 2 groups. The baseline demographic and tumor characteristics, in-hospital mortality rate, and 30-day mortality rate were comparable between the 2 groups. However, the patients in the resection group suffered from more serious complications compared with those in the TACE group (11.1% vs 4.7%, respectively, P < 0.01) as well as longer hospital stays (P < 0.05). The resection patients had significantly better overall survival rates than the TACE patients (P < 0.01). In the TACE group, patients with Lipiodol retention showed much higher 1-, 3-, and 5-year overall survival rates than those in the noncompact Lipiodol retention group (P < 0.01). Subgroup analyses revealed that patients with 1 to 3 tumor targets showed much better 1-, 3-, and 5-year overall survival rates in the resection group (P < 0.01), but no difference was observed for the patients with >3 targets. Our clinical analysis suggests that patients with BCLC stage B HCC should be recommended for resection when 1 to 3 targets are present, whereas TACE should be recommended when >3 targets are present.
