Debiri And Capecitabine In Refractory Prevalently Liver Metastases Of Colorectal Cancer: A Phase Ii Study.

724 Background: Treatment options for metastatic colorectal cancer (mCRC) patients refractory to chemotherapy are limited and clinical outcome is poor. In mCRC patients with liver-dominant disease hepatic locoregional therapy might be a treatment option. In this pilot study we evaluated the safety, tolerance, and efficacy of drug-eluting beads irinotecan (DEBIRI) in combination with capecitabine in the treatment of patients with mCRC with predominally liver disease. Methods: Twenty patients affected by liver metastasis of colorectal cancer were included in this study. All patients had progression of disease after two or more lines of chemotherapy and liver was the major or the predominant site of disease. DEBIRI, beads loaded with 100 mg irinotecan, was administered biweekly via hepatic artery. All patients assumed capecitabine 1,000 mg/m2 twice daily on days 1 to 14 every 3 weeks, until disease progression. Primary endpoints were safety, tolerance and overall responce rate (ORR); secondary endpoints were...
