Efficacy of Drug-Eluting Bead Transarterial Chemoembolization in the Treatment of Colorectal Cancer Liver Metastasis

Abstract

We aimed to investigate the efficacy and safety of drug-eluting bead transarterial chemoembolization (DEB-TACE) in the treatment of colorectal cancer liver metastasis. A total of 120 patients with colorectal cancer liver metastasis were divided into the TACE group (receiving TACE treatment, n = 60) and the DEB-TACE group (receiving DEB-TACE treatment, n = 60). At 1 month after treatment, the objective response rate (ORR) in the TACE group and DEB-TACE group were 65.0% (39/60) and 78.3% (47/60), respectively, and the disease control rate (DCR) was 78.3% (47/60) and 85.0% (51/60), respectively. Three months later, the ORRs in TACE and DEB-TACE groups were 63.3% (38/60) and 75.0% (45/60), and the DCRs were 76.7% (46/60) and 81.7% (49/60). We showed that the 1-year overall survival (OS) in TACE and DEB-TACE groups were 100% (60/60) and 88.3% (53/60), respectively, and the 2-year OS were 78.3% (47/60) and 61.7% (37/60). Further analysis indicated that the OS in the DEB-TACE group was significantly longer than that in the TACE group (P = 0.045). DEB-TACE is effective, safe, and feasible in the treatment of colorectal cancer liver metastasis, which can effectively improve the survival of patients.
