Combining transcatheter arterial chemoembolization with percutaneous ethanol injection therapy for small size hepatocellular carcinoma.
For patients with unresectable small size HCC, percutaneous ethanol injection therapy (PEIT) is used as a non-surgical treatment because it is difficult to achieve complete tumor necrosis by transcatheter arterial chemoembolization (TAE) alone. However, some small HCCs (<21 mm in diameter) are resistant to PEIT with incomplete tumor necrosis, which is associated with insufficient ethanol injection to the tumor. For more effective treatment for HCC, we performed a combination of TAE and PEIT on patients with small size HCC and evaluated the cumulative recurrence and survival rates. The recurrence rate in patients treated with the combination was less than that of TAE or PEIT alone. There were five patients without tumor recurrence during the follow-up period and three out of these underwent the combination treatment. The period of no recurrence was 33.4 months on average. In conclusion, we recommend combination therapy with TAE and PEIT for patients to accomplish more effective treatment of small size HCC.
