MSI status of colorectal carcinomas based on the results obtained by microfluidic-based chip analyses in comparison to prediagnosis
| Samples, n (%) | Prediagnosis by fluorescence-linked PCR-approach and laser detection | Estimation by label-free PCR and microfluidics |
| 12 (30) | MSI-H | MSI-H |
| 1* (2.5) | MSI-L | MSI-H |
| 1 (2.5) | MSI-L | MSI-L |
| 1* (2.5) | MSS | MSI-L |
| 25 (62.5) | MSS | MSS |
-
MSI, microsatellite instability; MSI-H, instability in more than one microsatellite locus (*discrepant data between the techniques applied); MSI-L, instability in one microsatellite locus; MSS, stability in all microsatellite loci.
