About this trial
This is an interventional treatment trial for Colorectal Cancer Metastatic focused on measuring Colorectal cancer, Fruquintinib
Eligibility Criteria
Inclusion Criteria: . The pathological diagnosis was colorectal adenocarcinoma liver metastasis; . Age: 18 to 75 years old,allgenders; . Patients who have previously received first-line chemotherapy and have achieved disease control (PR+SD) according to RECIST 1.1; . Patients with liver metastasis of colorectal cancer who have undergone curative local treatment (surgery, ablation, SBRT) and achieved no evidence of disease (NED). Definition of NED: a. After local treatment, no residual signs of primary or metastatic tumors are observed on CT, MRI, PET-CT imaging, or b. No cancer cells are found in biopsies of suspicious lesions; .Completed adjuvant chemotherapy after achieving NED (e.g. 4-8 cycles of CapOX regimen, 6-12 cycles of FOLFOX regimen, or without receiving adjuvant chemotherapy recently) and evaluated as no disease progression. Last chemotherapy within 2 months from enrollment. . The time interval between the last chemotherapy and enrollment does not exceed 2 months; . Performance status (ECOG score) ≤ 2 . Hematology: WBC > 3 × 10^9 / L; PLT > 80 × 10^9 / L; Hb > 90 g/L; . Liver function: ALT and AST ≤ 2.5 × ULN; bilirubin ≤ 1.5 × ULN; .Renal function: Serum creatinine ≤ 1.5 × ULN or creatinine clearance rate (CCr) ≥ 60 ml/min; .Signed informed consent, willingness to undergo treatment according to this protocol, and good compliance with medication. Exclusion Criteria: .Patients with tumor progression before enrollment following the completion of chemotherapy. .Intestinal obstruction or incomplete intestinal obstruction. .Co-existing with other serious illnesses, including severe electrolyte disorders, bleeding tendencies, etc. .Active or uncontrolled severe infections: a) Known human immunodeficiency virus (HIV) infection. b) Known clinically significant liver disease history, including viral hepatitis [known carriers of hepatitis B virus (HBV) must exclude active HBV infection, i.e., HBV DNA positive (>1×104 copies/mL or >2000 IU/mL)]. c) Known hepatitis C virus (HCV) infection with positive HCV RNA (>1×103 copies/mL), or other hepatitis, liver cirrhosis. .Women who are pregnant or breastfeeding and have childbearing potential but are not taking adequate contraceptive measures. .Patients with severe brain disorders or mental illnesses (such as depression, mania, obsessive-compulsive disorder, and schizophrenia) that affect the patient's ability to self-report. .Patients with autoimmune diseases, blood system disorders, and a history of organ transplantation, long-term use of steroids, or immunosuppressive agents. .History of other malignant tumors within the past 5 years, excluding cured cervical carcinoma in situ or basal cell carcinoma of the skin. .History of organ transplantation (including autologous bone marrow transplantation and peripheral stem cell transplantation). .Known or suspected allergies to the investigational drug fruquintinib. .Hypertension that cannot be well controlled with antihypertensive medications (systolic blood pressure ≥150 mmHg or diastolic blood pressure ≥100 mmHg). .Active cardiac disease within 6 months prior to treatment, including myocardial infarction, severe/unstable angina pectoris. Left ventricular ejection fraction <50% on echocardiography, poorly controlled arrhythmias. .Urinalysis indicating urine protein ≥2+ and 24-hour urine protein quantification >1.0g.

Arms of the Study
Arm 1
Experimental
Fruquintinib group
Patients will receive Fruquintinib maintenance treatment for six months, or until tumor recurrence, metastasis, or intolerable drug toxicities occur within six months. After achieving no evidence of disease (NED), a chest, abdomen, and pelvic CT scan with contrast or a chest CT scan with abdominal and pelvic MRI scan will be performed every 6 months within 2 years. Colonoscopy will be performed annually. CEA, CA19-9, and abdominal and pelvic ultrasound will be performed every 3 months. If abnormalities are found, further imaging studies and colonoscopy will be conducted, and if necessary, a PET/CT scan will be performed.
