Neoadjuvant Chemoradiotherapy Plus Sintilimab for Intermediate/High Immunoscore Locally Advanced Rectal Cancer
Recruiting now · Phase 2
Conditions studied: Rectal Cancer
In brief
Immunoscore has been reported to be superior to microsatellite instability staging in predicting the disease-specific recurrence and survival for patients with colorectal cancer. However, the relationship between Immunoscore and its impact on patient's response to PD-1 blockade remains to be elucidated. This phase II, prospective, open label study is designed to evaluate the efficacy and safety of combination neoadjuvant chemoradiotherapy (nCRT) with the anti-PD-1 antibody sintilimab for intermediate/high Immunoscore locally advanced rectal cancer.
