Summary

This study tested the drug tislelizumab given before surgery in 33 people with early-stage colorectal cancer that has specific genetic changes (MSI-H or dMMR).

What this could lead to

If successful, this could lead to a new treatment option that shrinks tumors before surgery, potentially improving outcomes for people with this specific type of colorectal cancer.
