Treatment efficacy of capecitabine combined with transcatheter arterial chemoembolization for hepatic metastases after colorectal carcinoma resection / 中华肝胆外科杂志

ABSTRACT

Objective To investigate the treatment efficacy of capecitabine combined with TACE for hepatic metastases after colorectal carcinoma resection.Methods The clinical data of 94 patients who were treated for hepatic metastases after colorectal carcinoma resection from June 2012 to December 2014 were retrospectively analyzed.The patients were divided into the combined group (48 patients) who underwent combined treatment of transcatheter arterial chemoembolization (TACE) and capecitabine,and the control group (46 patients) who were treated with TACE alone.The drug toxicities induced by chemotherapy in patients of the two groups were noted.The short-term outcomes and serum tumor markers were compared at 3-months after completion of TACE.All the patients were followed up and their overall survival was recorded.Results There was no significant difference in the frequency of TACE between the two groups (P ＞ 0.05).There were significant differences in the short-term outcomes at 3-month after completion of TACE (Z =2.000,P ＜ 0.05).The RR (complete response + partial response) and CBR (complete response + partial response + stable disease) were higher in the combined group than those in the control group [(52.1％ vs.32.0％) and (95.8％ vs.87.0％),respectively],although the differences were not statistically significant (both P ＞0.05).There were greater declines in CEA and CA19-9 levels at 3-month after completion of TACE in the combined group than the control group [(47.1 ± 10.3 vs.35.1 ±8.4) μg/L,(78.7 ± 19.6 vs.65.3 ± 17.0) kU/L],but the differences were not significant (t1 =5.776,t2 =7.849,both P ＜ 0.05).Toxic reactions were more common in the combined group than those in the control group,which included bone marrow suppression (39.6％ vs.30.4％) and peripheral neuritis (47.9％ vs.34.8％).Again,the differences were not significant (P ＞ 0.05).The median survivals were 17.3 months and 13.5 months,and 1-year survival rates were 72.9％ and 52.1％ in the combined group and the control group,respectively (x2 =4.325,P ＜ 0.05).There were significant differences in the survival between the two groups (x2 =4.097,P ＜ 0.05).Conclusions Capecitabine combined with TACE produced better treatment results for hepatic metastases after colorectal carcinoma resection.The short-term outcomes of the combined treatment was suDerior to TACE alone,and the treatment toxicities could be tolerated.
