    Abstract:
    BACKGROUND & OBJECTIVE: Transcatheter arterial chemoembolization (TACE) is the routine treatment for unresectable primary liver cancer, but 3-year survival rate of patients received TACE alone is only about 20%. This research was to evaluate efficacy of external radiotherapy (RT) combined with TACE on unresectable primary live cancer. METHODS: From Jun. 1994 to Apr. 2002, 114 patients with unresectable primary liver cancer were non-randomized to receive TACE plus RT (54 patients), or TACE alone (60 patients) as control. For TACE, after skiagram confirmed catheterization, suspension of 300 mg of carboplatin, 50-60 mg of epirubicin, 14-20 mg of mitomycin, and 10-30 ml of iodized oil was perfused into hepatic arteries, 1-2 mm of Gelfoam particles was given to embolize hepatic arteries according to blood supply conditions of tumors, this process was repeated every 4-8 weeks. Either group was treated with 1-4 sessions of TACE. In TACE+RT group, patients received radiation on tumor and generous margin 21-28 days after TACE. The radiation dose was 46-60 Gy in daily 2 Gy fractions. RESULTS: In TACE+RT group, response rate (AFP titer decrease of >50%) was 61.1%, and 1-, 2-, 3-year survival rates of TACE+RT group were significantly higher than those of TACE group (66.5% vs. 53.9%, 48.4% vs. 37.2%, and 37.4% vs. 17.8%, P<0.05). Three-year survival rate correlated with tumor size, liver function grade, and portal vein embolus. CONCLUSION: TACE combined with RT may prolong survival time of patients with unresectable primary live cancer.
