Abstract:
Objective To explore the clinical effect of radio frequency catheter ablation( RFCA) guiding by B ultrasound combined with CT on treating primary hepatic carcinoma. Methods Eighty-two patients with primary liver cancer were treated with transcatheter arterial chemoembolization therapy. One week after the operation,41 patients were treated with RFCA guiding by B ultrasound combined with RFA therapy and served as treatment group. Another 41 cases were given RFA treatment guiding by CT as control group. The indices including tumor shrinkage rate,survival rate of 0. 5,1 and 2 years. Results The tumor shrinkage and total effective rates in the treatment and control group were 95. 12%(39 / 41)and 80. 49%(33 / 41),and there was statistically significant difference between the two groups(χ2 = 5. 33,P < 0. 05). After treatment,the survival rates of 0. 5,1and 2 years in treatment group were 100%(41 / 41),82. 9%(34 / 41)and 73. 2%(30 / 41),and that of the control group were 100%(41 / 41),70. 7%(29 / 41)and 51. 2%(21 / 41). There was significant differences between groups in terms of the survival rates of 1and 2 years( χ2 = 3. 96,5. 07,P < 0. 05). Conclusion The curative effect of RFA guiding by B ultrasound combined with CT is significantly superior to that guiding by CT.
