Table 3.
Mutation profile | Surrogate marker (genetic) | Surrogate marker (IHC) |
---|---|---|
Ultramutated | POLE mutation | none available |
Hypermutated | MSI-H | MMR-D |
Copy-number high | TP53 mutation | p53 abn |
Copy-number low | absence of other markers | absence of other markers (p53 wt) |
MSI-H, microsatellite instability (high); MMR-D, mismatch repair deficient; abn, abnormal; wt, wild type
