Types
Intestinal and diffuse
Types: Intestinal
1. Associations
2. Commonly on […] of stomach
H. pylori, tobacco smoking, achlorhydria and chronic gastritis
Lesser curvature
Types: diffuse
1. Is it associated with H pylori
2. Associated with […] cells
Diffuse
1. No
2. Signet
Specific forms or precancerous forms of gastric cancer
Menetrier’s disease (pre-cancerous)
Krukenberg tumour
Sister Mary Joseph nodule
Linitis plastica
Menetrier’s disease
hyperplasia of the gastric mucosa
large, gastric folds on the body and stomach –> increased mucus production
parietal cell atrophy –> reduced HCl secretion
Krukenberg tumour
‘signet ring’ tumour
secrete mucin and readily metastasize to the ovaries.
Sister Mary-Joseph nodule
Subcutaneous peri-umbilical metastasis
Linitis plastica
leather bottle stomach
stomach muscles become more rigid –> holds less food
Risk factors
- Smoking
- H pylori
- >6 units of alcohol daily
What else?
Pernicious anaemia
Dietary nitrosamines (found in smoked foods and gastric cancer has higher incidence in Japan)
Atrophic gastritis
Blood group A
Adenomatous polyps
Achlorhydria (as seen in Menetrier’s disease)
Is GORD a RF for gastric cancer?
No –> for Barret’s oesophagus (intestinal metaplasia)
