Table 1 Pathologic classifications of gastric cancers (GCs)
From: Emerging molecular classifications and therapeutic implications for gastric cancer
Classification | Subtype | Characteristics |
|---|---|---|
Lauren | Intestinal | Recognizable glands, arise on a background of intestinal metaplasia |
Diffuse | Poor cohesiveness, round small cells, diffuse infiltration in the gastric wall with little or no gland formation | |
WHO | Tubular adenocarcinoma | Prominent dilated or slit-like, branching tubules |
Papillary adenocarcinoma | Well-differentiated tumor cells, exophytic growth | |
Mucinous adenocarcinoma | Extracellular mucinous pools | |
Signet-ring cell carcinoma | Cells lie scattered in the lamina propria, wide distances between the pits and glands |
