Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

pMMR/MSS and 32 dMMR/MSI-H patientspatients were planned to be enrolled. Patients with dMMR/MSI-H will be randomly assigned to the immunotherapy arm or short-course radiotherapy sequential immunotherapy arm; pMMR/MSS patients will receive capecitabine-irinotecan based concurrent radiotherapy before being randomly assigned to the XELIRI or FOLFRINOX arm.

The rate of complete response (sustained cCR for ≥ 1 year), long-term prognosis and adverse effects will be analyzed.
