Table 2. Estimation of sensitivity, specificity and accuracy of molecular MSI analysis.
IHC-negative (n) | IHC-positive (n) | Total | |
---|---|---|---|
MSI-positive (MSI-H) | 98 | 4 | 102 |
MSI-negative (MSS+MSI-L) | 4 | 882 | 886 |
Total | 102 | 886 | 988 |
MSS: microsatellite stability, MSI-L: low-microsatellite instability, MSI-H: high-microsatellite instability, n: number of cases.
