Transcatheter arterial chemoembolization therapy combined three-dimensional conformal radiotherapy Clinical observation of primary liver cancer

Objective To evaluate the clinical effect of transcatheter arterial chemoembolization (TACE) combined with three-dimension conformal radiotherapy (3DCRT) in treating unresectable primary Hepatic carcinoma(PHCC).Methods 64 cases of PHCC were randomly divided into 2 groups,TACE combined with 3DCRT group (Treatment group) and TACE alone group (control group).34 cases in treatment group were treated with TACE 2 ～3 times at first,after resting for 2-4 weeks,3DCRT treatment was used.30 cases in control group were treated with TACE 2 ～ 3 times only.Results The percentage of tumor regression rate (CR + PR) was 73.5% in treatment group and 36.6% in control group.The difference was significant (P ＜0.01).The percentage of AFP declined was 100% in treatment group and 92.9% in control group,which difference was not significant (P ＞0.05).The cumulative survival rate of 1-,2-and 3-years were 76.5%,58.8% and 41.2% in treatment group,and 56.7%,26.7%,13.3% in control group respectively.There was significant difference between the two groups (P ＜ 0.05).Conclusion The treatment of TACE combined with 3DCRT is an effective and security treatment method for primary Hepatic carcinoma.
