    Abstract:
    OBJECTIVE: To investigate the value of transarterial chemoembolization (TACE) using mixed emboli for hepatocellular carcinoma (HCC). METHODS: 188 patients with HCC were divided into two groups according to the treatment modality: 103 patients in group A treated by routine iodine embolus agent; 85 patients in group B by mixed iodine embolus agent (ultra-liquified iodinized oil + gelatin sponge + chemotherapeutic agents). The pattern of the arrested iodine deposition in the tumor, response, resectability during follow-up, pathological changes, survival and complications in the two groups were analyzed and compared. RESULTS: The pattern of full-and-dense iodine deposition in the tumor and the response rate (CR + PR) were 59.2% and 32.0% in group A, 89.4% and 56.5% in group B. Surgical resection after TACE was possible in 5.8% (6/103) of group A versus 15.3% (13/85) of group B. Complete tumor necrosis was observed in 1.0% and 4.7% in groups A and B, respectively. 1-, 2- and 3-year actual survival rates were 57.7%, 42.8% and 8.4% in group A, and 79.8%, 55.3%, 38.5% in group B. The difference in results between the two groups was statistically significant, however, the incidence of complication in the two groups was similar. CONCLUSION: Transarterial chemoembolization with mixed iodine emboli is more effective than with the routine iodine emboli in the treatment of bulky or nodular hepatocellular carcinoma rich in blood supply. Mixed iodine emboli is tolerable without increase in severe complications.
