4. One or more organs metastases, and the metastases are suitable for SBRT according to the evaluation of the researchers;
5. At least two or more standard systemic therapies prior treatment (based on Fu, oxaliplatin, irinotecan, bevacizumab and cetuximab) of cytotoxic chemotherapy, treatment failure or intolerable toxicities
6. ECOG 0-1
7. Patients must have measurable lesions
8. Expected overall survival ≥12 weeks

3. Risk factors of intestinal perforation: active diverticulitis, abdominal abscess, gastrointestinal obstruction, abdominal cancer or other known risk factors of intestinal perforation

5. Aspirin (\> 325 mg / day (maximum antiplatelet dose) or dipyridamole, ticlopidine, clopidogrel (≥ 75 mg) and cilostazol are currently used or have been used recently (within 10 days before the start of study treatment)
6. Thrombosis or embolism events such as cerebrovascular accident (including transient ischemic attack, cerebral hemorrhage, cerebral infarction) and pulmonary embolism occurred within 6 months before the start of the study
7. The researchers believe that the patient has a lesion and needs emergency palliative radiotherapy / emergency surgery (spinal cord compression, brain hernia, pathological fracture)
8. Known active infection and active tuberculosis infection were not included in the group; However, patients with hepatitis B virus (HBV) and hepatitis C virus (HCV) infection can be included in the group if their condition is stable after antiviral treatment;
9. There is evidence of pneumoperitoneum that cannot be explained by puncture or recent surgery;

14. Received any operation or invasive treatment or operation (except venous catheterization, puncture and drainage, etc.) within 4 weeks before enrollment
15. Patients have not recovered from all toxicities associated with prior anti-tumor therapy ,to acceptable baseline status, or a National Cancer Institute Common Terminology Criteria for Adverse Events(NCI CTCAE v5.0) Grade of 0 or 1, except for alopecia and oxaliplatin induced neurotoxicity ≤ 2 , and the previous surgery did not recover completely
16. Dysphagia or known malabsorption of drugs
17. Active gastric and duodenal ulcer, ulcerative colitis or uncontrolled hemorrhage in GI
18. Have evidence or history of bleeding tendency within 2 months after enrollment, the researcher assessed that moderate or severe bleeding tendency was not suitable for enrollment

24. There are concomitant diseases (such as severe hypertension, diabetes, thyroid disease, active infection, etc.) that seriously endanger the safety of patients or affect the completion of the study, or any laboratory abnormalities that are not suitable for participating in the clinical trial according to the judgment of the researcher
25. Active autoimmune disease or history of autoimmune disease with possible recurrence (including but not limited to: autoimmune hepatitis, interstitial pneumonia, uveitis, enteritis, hypophysitis, vasculitis, nephritis, hyperthyroidism, hypothyroidism);
26. Immunosuppressive agents or systemic hormones were used 14 days before the start of the study to achieve the purpose of immunosuppression (dose \> 10mg / day prednisone or other therapeutic hormones)
