Effect of XELOX regimens plus combination of endostar and thalidamide as first-line treatment for advanced colorectal cancer

Abstract

Objective To investigate the efficacy and safety of two antiangiogenic drugs (recombinant human endostatin endostar and thalidomide) combined with capecitabine and oxaliplatin(XELOX) regimens in the treatment of advanced colorectal cancer. Methods From January 2015 to May 2018, 40 patients of advanced metastatic colorectal cancer with organ metastasis and non-resectable were selected from the first people′s hospital of Hefei and Anhui Provincial Hospital, and they were randomly divided into treatment and control group, with 20 cases in each group.The treatment group received intravenous infusion (IV) of endostar for continuous 7 days (day 1~7) combined with oral administration of thalidomide for continuous 14 days (day 1~14) plus XELOX regimens after the fifth dose of endostar (day 6~19), and the control group was treated with XELOX regimen (day6~19). Results The objective response rate (ORR) was 50% (10/20) and 20% (4/20) respectively (χ2=3.956, P 0.05), and the median progression free survival (mPFS) was 6.8 in both groups.There was no significant difference in Karnofsky performance score (KPS) and incidence of adverse reactions between the two groups before and after treatment (P>0.05). Conclusion Combination of endostar and thalidamide plus XELOX regimen as first-line treatment have better antitumor activity and are well-tolerated in patients with advanced colorectal cancer.
