In 2019, Austrian scientist Gerd conducted a preliminary analysis of FGF18 mRNA expression data of 87 patients with esophagogastric junction adenocarcinoma(AEG) in the Cancer Genome Atlas (TCGA) database, predicting that FGF18 has a high level of expression in AEG. This evidence concerns the gene FGF18 and gastroesophageal junction adenocarcinoma.
