chronic gastritis
old age
histology and appearance of T1GC
glandular
large irregular
location of T1GC
antrum and lesser curvature
rf for T2GC
blood type a

histology and appearance of t2gc
- poorly differentiated
- signet ring cells
- gastric linitis - submucosa invasion
location OF T2GC
anywhere- esp cardia of the stomach
why is T2GC more common in the cardia of stomach
defective adhesion bc CDH-1 mutation — defective e cadherin —- increase in ability to invade and spread
