Abstract excerpt
Recent clinical evidence has demonstrated that microsatellite instability (MSI) or defective mismatch repair (MMR) and high tumor mutational load can predict response to the programmed cell death 1 (PD-1) receptor inhibitor pembrolizumab in metastatic colorectal cancer (mCRC). Mutations in polymerase ε (POLE), a DNA polymerase involved in DNA replication and repair, contribute to an ultramutated but...
