on the other hand , the location of the tumor showed a significant relation to gastritis : the progression of gastritis was more rapid ( high mean aas value ) and the prevalence of atrophic gastritis was higher in the tumor-affected area ( i.e. , in the antrum in patients with antral [ distal ] tumors ; in the body in patients with body [ proximal ] tumors ) , than in the general population , but were similar in the tumor-free area in both gc patients and controls .
