Side Effect/Complication Risk Related to Injection Branch Level of Chemoembolization in Treatment of Metastatic Liver Lesions from Colorectal Cancer.

Chemoembolization using Irinotecan-loaded microspheres was relatively well tolerated by patients and gave a low risk of significant complications, which did not change with the branch level of microsphere administration. However, an association was found between the branch level of chemoembolization and the severity of postembolization syndrome. Further research is needed to determine the most effective DEB-TACE chemoembolization technique.
