Clinical Trial Summary

This is a prospective, open-labelled study to evaluate the efficacy and safety of sequetial transarterial chemoembolization with lipiodol and neoadjuvant chemotherapy in the treatment of initial unresectable colorectal cancer. The progression-free-survival (PFS) will be evaluated as the primary endpoints.
