Gastric Cancer Risk Stratification Test (ABC Classification), eradicated [LA] Report

• ABC Classification		Helicobacter Pylori Antibody
  		< 10 (-)	≥ 10 (+)
  Pepsinogen	(-)	Group A	Group B
  	(1+) - (3+)	Group D	Group C

• Group A	Generally healthy gastric mucosa and low risk of gastric disease. Pay attention to diseases not related to H. pylori, such as reflux esophagitis. Although most likely uninfected, a portion of the population includes those with H. pylori infection or a history of infection. It is ideal to undergo an imaging test such as endoscopy at least once.
  Group B	Slightly weakened gastric mucosa. Pay attention to gastric and duodenal ulcers. There is also a risk of gastric cancer. Undergo an endoscopic examination. Treatment for eradication of H. pylori is recommended.
  Group C	Weakened gastric mucosa with advanced atrophy. This type is prone to gastric cancer. Regular endoscopic examinations are recommended. Eradication of H. pylori is also recommended.
  Group D	Gastric mucosa with very advanced atrophy. There is a risk of developing gastric cancer and other diseases. Diagnosis of H. pylori infection is recommended. Please consult a specialized medical institution for diagnosis, such as an endoscope.
  Group E	Those who have undergone eradication of H. pylori should undergo regular endoscopic examinations as Group E (eradication group) regardless of the result of the eradication determination. Although the risk of developing gastric cancer in group E is reduced by eradication, it is not zero, so endoscopic follow-up is necessary even after eradication.
