Summary

Though surgical resection remains the primary choice for advanced rectal cancer, about 80% are considered unresectable due to the number, size, or location of metastases. The overall prognosis of patients who accepted traditional treatment methods is still poor. Therefore, the investigators designed a combination therapy, short-course radiotherapy followed by chemotherapy with target therapy and anti-PD-1 immunotherapy. This study implement the combination therapy in patients with rectal cancer who are initially unresectable in the locally advanced stage with multiple liver/pulmonary metastases, to evaluate whether they can improve the objective response rate, the conversion rate of radical surgery and prolong the overall survival of patients, and strive to provide high-level medical evidence for the clinical treatment.

Conditions

  • Advanced Rectal Cancer
  • Distal Metastasis

Interventions

COMBINATION_PRODUCT

a combination therapy including tislelizumab

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.
