Abstract: Objective To investigate the impact of blood supply on treating metastatic liver cancer with transcatheter arterial chemoembolization (TACE).Methods Clinical efficacy and survival rate were analyzed on 34 cases of metastatic liver cancer that were treated by TACE.Results Metastatic liver cancer was lack of blood supply-based.The values of CR+PR in hypervascular group and lack of blood supply group were 66.7% (8/12) and 31.8% (7/22) respectively，and the difference between the two groups was statistically significant (P＜0.05).The survival rates of 6-and 12-month after metastasis in hypervascular group were 100% and 75.0% respectively，while in lack of blood supply group were 81.8% and 40.9% respectively.The median survival periods after metastasis in hypervascular group and lack of blood supply group were 21.6 and 13.5 months respectively，and the difference between the two groups was statistically significant (P＜0.05).Conclusion TACE is significantly more effective for treating metastatic liver cancer with rich blood supply.
