Tissue microarray-chip featuring computerized immunophenotypical characterization more accurately subtypes ampullary adenocarcinoma than routine histology

Figure 4 Statistical analyses of immunohistochemical markers and their values. A: Mean immunohistochemical value for each marker in INTestinal, Pancreato-Biliary and MIX types of ampullary adenocarcinomas, according to histological analyses (hematoxylin-eosin staining); B: Mean immunohistochemical value to compare intestinal vs Pancreato-Biliary; C: Global Score mean value in all sub-types of AACs; and D: Chi-square test to compare the histological vs molecular sub-types. AACs: Ampullary adenocarcinomas; IHC: Immunohistochemical; INT: Intestinal; PB: Pancreato-Biliary.
