Helicobacter pylori associated chronic gastritis, clinical syndromes, precancerous lesions, and pathogenesis of gastric cancer development

Table 1 Operative link for gastritis assessment staging system

Atrophy score		Corpus
		No atrophy	Mild atrophy	Moderate atrophy	Severe atrophy
		(score 0)	(score 1)	(score 2)	(score 3)
Antrum	No atrophy (score 0) (including incisura angularis)	Stage 0	Stage I	Stage II	Stage II
	Mild atrophy (score 1) (including incisura angularis)	Stage I	Stage I	Stage II	Stage III
	Moderate atrophy (score 2) (including incisura angularis)	Stage II	Stage II	Stage III	Stage IV
	Severe atrophy (score 3) (including incisura angularis)	Stage III	Stage III	Stage IV	Stage IV

The stage of gastritis results by combining the atrophy score values as obtained in antral and corpus biopsy samples[84,85].
