Gastric Cancer Risk Stratification Test (ABC Classification) [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.
