UWG02CTC also showed higher expression than UWG01CTC of targetable pathways including EGFR, FGFR2, HER-2 (ERBB2), and MET, as well as key genes in the JAK/STAT pathway, genes which overexpression are frequently reported in gastric adenocarcinomas but not gastrointestinal neuroendocrine cancers16,30,31. Here, ERBB2 is linked to gastric adenocarcinoma.
