Methods： A total of 1003 gastric cancer specimens resected surgically between 1992-2005 in Zhuanghe Center Hospital were studied. The specimens were fixed in formalin and diagnosed by routine pathology. Results： The incidence of patients with gastric cancer was highest at age of 60-69, the next high was at age of 50-59 and it was significantly higher in male than in female （P〈0.001）, the ratio was 3.0：1. During the past 14 years, there were 159 （15.9%） EGC, 195 （19.4%） moderate and 649 （64.7%） advanced gastric cancer detected. In macroscopical features, type Ⅲ remained dominant in EGC, the next was mixed type in EGC. In advanced gastric cancer the Borrmann＇s type Ⅲ remained the dominant, the next was type Ⅱ. For nodal metastasis, positive cases were decreasing and negative were increasing in EGC, moreover negative cases were higher than positive ones each year. There was no obvious trend in advanced cancer but positive cases were higher than negative ones each year. In histological features, papillary, moderately and poorly differentiated tubular adenocarcinoma remained downtrend, mucus adenocarcinoma and undifferentiation cancer remained uptrend year after year. The radio of intestinal to diffuse type decreased from 0.78 to 0.62 during the past 14 years. Conclusion： There were significant chorological trends of pathological characteristic of gastric cancer in Zhuanghe high-risk area during the past 14 years.展开更多
