Abstract：Objective To investigate the effect of Kang′ai Injection on liver function in patients with colorectal cancer liver metastasis after transcatheter arterial chemoembolization (TACE).Methods A total of 46 patients with colorectal cancer liver metastasis who were admitted to our hospital from January 2014 to December 2016 were selected as the research subjects.They were divided into control group and study group according to the order of admission, with 23 cases in each group.Both groups were treated with TACE, patients in the control group received regular liver protection therapy alone, while patients in the study group received Kang′ai Injection on the basis of regular liver protection therapy.The treatment effect, clinical main symptoms, serum liver function indicators (alanine transaminase [ALT], aspartate transaminase [AST], total bilirubin [TBil], total bile acid [TBA]and albumin [ALB]), tumor markers (carcinoembryonic antigen [CEA], carbohydrate antigen 19-9 [CA19-9]and alpha-fetoprotein [AFP]), and Karnofsky (KPS) scores before and after treatment in the two groups were compared.Results There were no significant differences in the incidence rates of pain in the liver area, fever and jaundice before treatment between the two groups of patients (P＞0.05).The incidence rates of pain in the liver area, fever and jaundice of the two groups after treatment were lower than those before treatment, and those in the study group were lower than those in the control group, the differences were statistically significant (P＜0.05).After treatment, the levels of ALT, AST, TBil, and TBA in the study group were lower than those in the control group, and the ALB level was higher than that in the control group, the differences were statistically significant (P＜0.05).There were no significant differences in the levels of tumor markers between the two groups after treatment (P＞0.05).The total effective rate of treatment in the study group (60.9%) was higher than that in the control group (52.2%), and the difference was statistically significant (P＜0.05).There was no significant difference in KPS score between the two groups after treatment (P＞0.05).Conclusion Kang′ai Injection has a better protection of liver function, can be used as an adjunct to prevent colorectal cancer liver metastasis after TACE from liver damage, and can also indirectly improve the overall therapeutic effect of colorectal cancer liver metastasis.
