- Hepatitis C (defined as a positive test result for hepatitis C virus antibody [HCV-Ab]) ;
- history of tuberculosis infection or treatment within 1 year prior to signing informed consent;
- presence of severe infection within 4 weeks prior to first dose, including but not limited to bacteremia requiring hospitalization, severe pneumonia, etc.; or active infection requiring systemic antibiotic therapy according to NCI-CTCAE v5.0 grade ≥ 2 within 2 weeks prior to first dose, or unexplained fever >38.5°C during screening/prior to first dose (at the investigator's discretion, due to oncologic causes fever due to tumor causes may be enrolled);
- previous allogeneic bone marrow transplantation or solid organ transplantation received or intended to be received;
- Hemoptysis with a maximum daily hemoptysis of approximately ≥2.5 ml within 2 months prior to signing informed consent; clinically significant bleeding symptoms or a clear bleeding tendency within 1 month prior to signing informed consent, e.g. gastrointestinal bleeding, bleeding gastric ulcer, fecal occult blood ++ at baseline, vasculitis; known hereditary or acquired bleeding and thrombotic tendencies, e.g. hemophilia, impaired coagulation skills, thrombocytopenia, hypersplenism, etc.;

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: unresectable group
Patients will receive tislelizumab in combination with radiotherapy and targeted therapy. 2 weeks after large fractionated radiotherapy for primary rectum lesion and metastasis, patients will be treated with systemic treatment including chemotherapy combined with targeted therapy and immunotherapy.
Patients will be evaluated by MDT every 2 months since the beginning of the treatment.
Those who are regarded as NED will be treated surgically/locally.
Those in stable or partial remission will continue with combination therapy.
Those with progressive disease will be withdrawn from study.
Patients who are not surgically treatable will continue with combination therapy until disease progression or receiving surgical treatment.
|
For liver/pulmonary metastasis, the treatment plan is to implement large fraction radiotherapy for 4-8 times. For primary rectum lesion, short-course radiotherapy regimen through intensity-modulated radiotherapy will be applied with dose of 25Gy/5Fx. Immunotherapy contains anti-PD-1 monoclonal antibody, Tislelizumab(200mg, d1, q3w, i.v). For patients with RAS or BRAF mutation, chemotherapy adopts FOLFOX+BEV plan. For patients without RAS or BRAF mutation, chemotherapy adopts FOLFIRI+CET plan. Patients will be followed for safety during the study. The safety follow-up period is defined as 90 days after the last dose of tislelizumab. Safety related data will be collected from the time of signing the informed consent until the end of the safety follow-up period or the start of new therapy.
