    Abstract:
    BACKGROUND/AIMS: Hepatectomy has been accepted as a reliable cure for primary hepatocellular carcinoma (HCC). However, the residual liver recurrence rate after hepatectomy remains high. To improve the prognosis after hepatectomy for HCC, repeated post-operative transcatheter arterial infusions of anticancer drugs and lipiodol (TAI) was given. This study evaluates the efficacy of this treatment for preventing residual liver recurrence after hepatectomy. METHODOLOGY: TAI after hepatectomy was performed in 24 (TAI group) of 65 cases showing tumor invasion such as infiltration to the capsule, intraportal spread, and intrahepatic metastasis. In TAI, a mixture of Mitomycin C (MMC) and Adriamycin (ADM) is administered with lipiodol via the hepatic artery. The recurrence and survival rates of the TAI (n = 24) and non-TAI (n = 41) groups were compared to evaluate the efficacy of TAI after hepatectomy. RESULTS: The TAI group had a lower cumulative residual liver recurrence rate than the non-TAI group (p < 0.01). Division of residual liver recurrence cases into two groups according to the duration of recurrence showed that the rate of recurrence within 1 year after hepatectomy was lower in the TAI group (10.0%) (1/10) than in the non-TAI group (48.4%) (15/31) (p = 0.07). Also, the cumulative survival rate in the TAI group was significantly higher (p < 0.05). The morbidity rate was 16.6%. Bilomas occurred without infection in 2 cases, and liver abscess in one. CONCLUSIONS: TAI may be an effective surgical adjuvant against residual liver recurrence, and we suggest that its effectiveness results from suppression of intrahepatic micrometastases rather than multicentric carcinogenesis.
