The aim of this study is to evaluate the safety and efficacy of hepatic arterial infusion chemotherapy combined with fruquintinib in later treatment for colorectal cancer liver metastases. All patients received FOLFOXIRI-based HAIC chemotherapy and oral fruquintinib. The primary end point was objective response rate (ORR), and the secondary endpoints were disease control rate (DCR), the liver-specific ORR, overall survival (OS), progression-free survival (PFS), liver-specific PFS, duration of response(DoR)and safety.
