Combination of transcatheter arterial chemoembolization using cisplatin-lipiodol suspension and percutaneous ethanol injection for treatment of advanced small hepatocellular carcinoma

Background: We evaluated the long-term efficacy of the combination of transcatheter arterial chemoembolization (TACE) using cisplatin-lipiodol suspension and percutaneous ethanol injection (PEI) for treatment of advanced small hepatocellular carcinoma (HCC). Patients and methods: Sixty-nine patients with HCC less than 3 cm in diameter and at most three lesions were enrolled in this study. HCC nodules were confirmed to be hypervascular by angiography. Thirty-two patients were treated with a combination of TACE and PEI (TACE/PEI group) and 37 patients with TACE alone (TACE group). Results: The 5-year survival rates were 50% for the TACE/PEI group and 22% for the TACE group. The TACE/PEI group had a slightly but not significantly better survival than the TACE group. The 5-year survival rates of patients with solitary HCC were 61% for the TACE/PEI group and 24% for the TACE group. Although the two therapeutic groups both had high rates of recurrence, the rates in the TACE/PEI group were significantly lower than those in the TACE group (P <0.05). Severe complications such as intraperitoneal bleeding and segmental hepatic infarction were observed at low incidence, and recovered with supportive treatment. Conclusions: The combination of TACE and PEI appears to prolong survival, compared with TACE alone. This combination therapy can thus be a valuable form of treatment for unresectable advanced small HCC.
