Objective： The aim of our studywas to discuss changes in the clinicopathological characteristics of gastric cancer in hehuang valley of China in recent 10 years. Methods： A retrospective case-control study was performed on 2379 newly-diagnosed gastric cancer patients. All of them came from hehuang valley. The patients were divided into two groups [recent 5 years （R5Y） and late 5 years （L5Y）] from February 2003 to February 2013, and the clinicopathological data were surveyed retrospectively. Results： The constituent ratio of upper 1/3 gastric cancer in R5Y and L5Y was 33.5% and 20.7%, respectively, and it showed a significant difference between the two groups （X2 = 21.28, P = 0.00）, The constituent ratio of squamous carcinoma/adenosquamous carcinoma was 2.7% and 1.6%, respectively, and it also showed a significant differ- ence between two groups （X2 = 50.91, P = 0.00）. The constituent ratio of moderately-poorly differentiated/poorly differentiated gastric carcinoma was 84.2% and 50.2%, respectively, and it showed statistically significant difference （X2 = 30.28, P = 0.00）. The detection rate of early gastric cancer （EGC） was 1.47% （35/2379）. The constituent ratio of the types of Borrmann II and Borrmann IV of advanced gastric cancer （AGC） among 2379 cases was 47.6% and 40.8%, respectively, and that still showed statistically significant difference （X2 = 18,80, P = 0.00）. The constituent ratio of diffuse-type of gastric cancer in R5Y and L5Y was 36.2% and 30.8%, respectively, even there was a significant difference （X2 = 7.49, P = 0.01）. Furthermore, there were also significant differences in regional lymph nodes metastasis, perineural infiltration and vascular invasion （P 〈 0.05）. The positive detection rate of HER2, ER and PR was 14.88%, 17.23% and 15.93%, respectively. The constituent ratio of HP in two groups was 43.8% and 36.2% respectively, and it also showed a significant difference （~2 = 13.51, P = 0.00）. Conclusion： The pathogenic sites in gastric cancer chan
