Liver is the most common metastatic site in patients with colorectal cancer (CRC) and the leading cause of death in patients. Surgery is the best way to cure CRLM, but few patients can receive surgery, and patients prone to recurrence after surgery. It is an urgent topic to choose an effective treatment method with less side effects for CRLM patients. HAIC is a unique and effective treatment option for CRLM patients. Fruquintinib is a small molecule angiogenesis inhibitor, and has been recommended for third-line treatment of metastatic colorectal cancer (mCRC). Tislelizumab is a humanized IgG4 anti-PD-1 monoclonal antibody, meanwhile, tislelizumab shows significant and durable antitumor activity in patients with CRC, and is well tolerated.
This is a single-center, single-arm, open-label clinical study, to explore the efficacy and safety of fruquintinib combined with tislelizumab and HAIC (hepatic arterial infusion chemotherapy) in patients with colorectal liver metastases cancer (CRLM) who failed standard therapy.
