Figure 1

Examples of NEN metastasis and the proportion of regional lymph nodes that exhibit histological tumor involvement, Chromogranin A immunohistochemical positivity or Chromogranin A transcript expression. A NEN lymph node metastasis stained with H&E stain, 20X (1a) and Chromogranin A IHC stain, 20X (1b) on contiguous slices of an involved lymph node. There was a significant difference between the proportion of positive tumors (p = 0.020), and Dunn’s post hoc tests showed a significant difference between H&E staining or CgA PCR (1c).
