Brief summary: Liver metastasis is the main cause of death in patients with colorectal cancer. The treatment of liver metastasis of colorectal cancer is the key to prolong the survival of patients. The purpose of this study was to investigate the efficacy and safety of fruquintinib combined with Camrelizumab and HAIC regimen in the treatment of non-MSI-H advanced colorectal cancer patients with liver metastasis after first-line standard treatment failure. Compared with the current standard second-line treatment plan, it provides new decisions for clinical practice, in order to reduce the adverse reactions of treatment and improve the tolerance and efficacy of patients. To provide more and more optimized medication options for patients with non-MSI-H advanced colorectal cancer complicated with liver metastasis.

Detailed description: This is a single-center, open, double-cohort clinical study to explore the non-MSI-H type advanced colorectal cancer patients with liver metastases after the failure of first-line standard treatment with fruquintinib combined with calelizumab and HAIC.Clinically, systemic chemotherapy with 5-FU as the core, combined with irinotecan or oxaliplatin is the first-line and second-line standard chemotherapy regimen for unresectable CRLM patients, but various hepatotoxicity will occur during chemotherapy. HAIC can selectively deliver chemotherapeutic drugs to tumor cells, reduce hepatocyte toxicity, relatively preserve liver parenchyma, and increase the concentration of chemotherapy in the tumor. Tumor cells are exposed to chemotherapy for a longer time, which effectively improves the efficacy and safety of treatment. Anti-angiogenic drugs can hinder the growth of microvessels in tumors and the development of metastatic diseases. At present, multiple retrospective studies have provided evidence support. The response rate of HAIC combined with systemic targeted therapy can reach 74 % -92 %. Previous studies have suggested that anti-angiogenic drugs combined with immunotherapy is expected to be a treatment strategy for patients with advanced colorectal cancer who fail to receive standard treatment or cannot receive standard treatment. Therefore, this study investigated the efficacy and safety of fruquintinib combined with Camrelizumab and HAIC in the treatment of patients with non-MSI-H advanced colorectal cancer complicated with liver metastasis after first-line standard treatment failure.

Eligibility criteria: Inclusion Criteria:

* The subjects volunteered to join the study and signed informed consent, with good compliance and follow-up.

* Male or female patients with fertility voluntarily used effective contraceptive methods, such as double-barrier contraceptive methods, condoms, oral or injectable contraceptives, intrauterine devices, etc., during the study period and within 6 months of treatment in the last study. All female patients will be considered to have fertility, unless the female patient has natural menopause, artificial menopause or sterilization ( such as hysterectomy, bilateral adnexectomy or radioactive ovarian irradiation, etc. ), otherwise the female patient 's serum or urine test showed no pregnancy within 7 days before the study, and must be non-lactating patients.

* Participating in other clinical trials and received at least one treatment within 4 weeks before enrollment
* Patients with autoimmune disease or history of autoimmune disease within 4 weeks before enrollment
* patients currently have central nervous system (CNS) metastasis or previous brain metastasis and the symptom control time is less than 2 months
* Patients cannot take fruquintinib orally
* Patients who have received organ transplantation and bone marrow transplantation in the past
* Have taken other strong inducers or inhibitors of CYP3A4, P-gp substrates and BCRP substrates within 2 weeks before the First medication
* Received any operation (except biopsy) or invasive treatment or operation (except venous catheterization, puncture and drainage, etc.) within 4 weeks before enrollment
* Pleural effusion or ascites causing relevant clinical symptoms, including respiratory syndrome (dyspnea≥CTC AE grade 2)
* Clinically significant electrolyte abnormality#
* Systolic blood pressure \> 140mmHg or diastolic blood pressure \> 90mmHg regardless of any antihypertensive drugs; Or patients need more than two antihypertensive drugs
* Proteinuria ≥ 2+ (1.0g/24hr);
* Active gastric and duodenal ulcer, ulcerative colitis or uncontrolled hemorrhage in GI, or other conditions that may cause GI bleeding and perforation as determined by the investigator;
* Have evidence or history of bleeding tendency within 3 months or thromboembolic events within 12 months before enrollment( Hemorrhage \> 30 mL within 3 months, hematemesis, black feces, hematochezia ), hemoptysis ( fresh blood \> 5 mL within 4 weeks ) or thromboembolic events ( including stroke events and / or transient ischemic attack ) within 12 months ;

Accompanied by family or social factors, which will affect the safety of patients.
