[Pathologic comparison between gastric carcinoma and lesions in peri-cancerous mucosa from two districts with different mortality rates in Gansu Province].

A pathologic comparative study on gastric carcinoma and lesions in peri-cancerous mucosa was done in 222 resected specimens of gastric carcinoma from two districts with different mortality rates in Gansu province. The adjusted mortality rates were 46.41 per 100,000 and 21.64 per 100,000 respectively. There were no significant difference in the histologic type and the gastric, intestinal and mixed types classified according to mucin histochemical stain and no significant difference in the detection rate of chronic atrophic gastritis (CAG), intestinal metaplasia (IM) and dysplasia in peri-cancerous mucosa either. These findings suggest that the type of gastric carcinoma be not related to the mortality rates either high or low and neither was there any apparent correlation between the CAG, IM and gastric carcinoma.
