Effect of transcatheter arterial chemoembolization combined with radiofrequency ablation in the treatment of liver cancer

Objective To investigate the effect of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) in the treatment of liver cancer, and its influence on the serum markers. Methods 108 patients with primary liver cancer were selected as the subjects of this study.According to the random number table method, the patients were divided into two groups.The control group (54 cases) received TACE treatment, and the observation group (54 cases) received TACE combined with RFA treatment.The treatment effects, the changes of tumor recurrence related indicators and the levels of tumor related indicators were compared and analyzed. Results The effective rate of the observation group was 79.7%(43/54), which was significantly higher than 50.0%(27/54) of the control group (χ2=10.391, P=0.001). After treatment, the E-calcium protein (EC), vascular endothelial growth factor (VEGF), matrix metalloproteinase (MMP), tumor recurrence index alpha fetoprotein (AFP), CA199, glutamate transferase (GGT) levels in the observation group were (1 738.8±114.8)μg/L, (207.9±37.2)ng/L, (34.9±4.6)ng/L, (72.2±19.5)μg/L, (34.2±5.1)U/L, (88.9±9.4)U/L, respectively, which were significantly lower than those in the control group[(2 382.4±159.4)μg/L, (367.3±49.3)ng/L, (72.1±7.4)ng/L, (135.2±21.8)μg/L, (66.9±8.2)U/L, (124.6±12.5)U/L], the differences were statistically significant(t=24.076, 18.967, 31.373, 15.828, 24.884, 16.774, all P<0.05). Conclusion TACE combined with RFA is effective in the treatment of liver cancer, which can effectively kill tumor cells and reduce the contents of serum tumor markers, and it is worthy of popularizing in clinic.
