 Companion diagnostics is an important tool for selecting patients with cancer who are most likely to clinically benefit from a particular molecular-targeted drug. This report focuses on the companion diagnostics for HER2-overexpressing gastric cancer. Intra-tumor heterogeneity in gastric cancer is an important phenomenon, so we need to recognize that reported HER2 status represents only a fraction of gastric cancer tissue. For accurate immunohistochemical diagnosis of gastric cancer using formalin-fixed, paraffin-embedded blocks, each process for sample preparation, fixation and storage need to be appropriate.
