[0R627 8, 0R628 7] [R627 5, R628 2]Gastric cancer risk screening (ABC classification), LA (criteria)

• ABC classification		Helicobacter pylori antibody
  		< 10 (-)	≥ 10 (+)
  Pepsinogen	(−)	Group A	Group B
  	(1+) - (3+)	Group D	Group C

• Group A	The gastric mucosa is generally in good health. The risk of suffering from stomach disease is low. Pay attention to diseases not associated with H.pylori such as reflux esophagitis. Although it is unlikely to be infected, this group includes patients currently or previously infected with H.pylori. It is ideal to have imaging diagnosis such as endoscopy just once.
  Group B	The gastric mucosa is slightly deteriorated. Pay attention to stomach ulcer and duodenal ulcer. Take endoscopy since you have a risk of gastric cancer. H.pylori eradication is recommended.
  Group C	The gastric mucosa is deteriorated with advanced atrophy. This type is susceptible to gastric cancer. Periodic endoscopy is recommended. H.pylori eradication is also recommended.
  Group D	More severe gastric mucosal atrophy is detected. You have a risk of gastric cancer. H.pylori infection diagnosis is recommended. Be sure to visit a specialist medical institution for consultation to receive diagnosis using endoscopy etc.
  Group E	Patients who received H.pylori eradication therapy are reported as Group E (H.pylori eradicated group) regardless of results. The gastric cancer risk becomes low, but the endoscopy is necessary regularly.
