Summary
10%-15% of early-stage colon cancers harbour either deficient mismatch repair (dMMR), microsatellite instability high (MSI-H) is characterised by high tumour mutational burden and increased lymphocytic infiltrate. Metastatic dMMR colon cancers are highly sensitive to immune checkpoint inhibition.The MSI phenotype is associated with a better prognosis than MSS in stage II and III CRCs. However, there are conflicting data about the benefit of adjuvant chemotherapy in this group of patients. We are conducting a single arm study phase II trial to determine if the anti-PD-1 antibody Tislelizumab improves disease-free survival (DFS) in patients with high risk stage II and stage III dMMR/MSI-H colon cancer.
