Table 3. Cross-tabulation for concordance or H&E-classification and IHC-classification with classification of resection specimens.

Combining all TMA cores to a single diagnosis IHC-classification shows higher concordance with the diagnosis made upon the resection specimen as consensus H&E diagnosis of the TMA cores.
