To characterize a cohort of gastro-esophageal adenocarcinomas (GEA) evaluated for HER2 gene amplification using bright field in situ hybridization (ISH) following the 2016 guidelines for GEA and correlating the results with clinico-pathological features. It was also aimed to evaluate the effect of applying the ISH criteria from the 2018 guidelines for breast cancer (BC) in the same GEA cases. 159 GEA cases collected in a period of 59 months were evaluated for HER2 gene amplification by ISH according to GEA and BC guidelines.
