Safety and Efficacy of Polyvinyl Alcohol Sodium Acrylate Embolization Microspheres for CRLM

This study is a prospective, multicenter, randomized controlled clinical trial. Seventy-two patients with colorectal cancer liver metastases that are not feasible or suitable for surgical resection will be enrolled in this study. The experimental group received transcatheter arterial chemoembolization (TACE) treatment with polyvinyl alcohol sodium acrylate embolization microspheres loaded with 100mg irinotecan and the control group received TACE treatment with HepaSphere Microspheres loaded with 100mg irinotecan. All patients received 1-2 TACE treatment as needed. The primary end point of this study is disease control rate (DCR) of target lesions 1 month after the last TACE treatment.
