The clinical question under study did not include the formal management of gastric cancer, and the model thus stops at the time of its detection.
Only a limited number of biomarkers are available for detection and prognostic evaluation of gastric cancer.
Being associated with each other, distal gastric cancer and helicobacter infection show certain similar features in their worldwide occurrence and epidemiology.
Subsequently, the stomach wall was inspected for worms attached to or buried in the gastric mucosa.
A decrease in the rate of detection at first visit would delay diagnosis of gastric cancer, which may influence prognosis.
The molecular changes differ between the two major types of gastric cancer: intestinal- and diffuse-type tumours.
Endogenous ulcerogenic factors are pepsin and gastric acid secretion, levels of which are relatively preserved in aging.
To advance our knowledge and discover new biomarkers for gastric cancers, utilisation of the genomic database is essential.
