TCGA divides gastric cancer into four molecular subtypes:implications for individualized therapeutics

摘要

Gastric cancer is a leading cause of cancer deaths in the world. The treatment of gastric cancer is challenging because of its highly heterogeneous etiology and clinical characteristics. Recent genomic and molecular characterization of gastric cancer, especially the findings reported by the Cancer Genome Atlas(TCGA), have shed light on the heterogeneity and potential targeted therapeutics for four different subtypes of gastric cancer.
