Abstract
AIM: To explore the clinicopathological variation trend of gastric cancer from 1999 to 2006 in Yixing city and to provide information for gastric cancer prevention.
METHODS: A total of 1022 pathologically confirmed gastric cancer cases were subdivided into 2 groups. Group A comprised cases from 1999 to 2002, while group B consisted of cases from 2003 to 2006. Statistical analysis were conducted on age, gender, tumor size, tumor location, pathologic-TNM stage and differentiation of tumor cells.
RESULTS: In both groups, gastric cancer occurred mainly at gastric body, cardia part and antyum. Interestingly, as compared with group A, there was a decreasing trend in the proportion of gastric carcinoma at gastric body (χ2 = 21.59, P< 0.05), and an increasing proportion at stomach angle (χ2 = 33.16, P < 0.05). The proportion of poorly-differentiated adenocarcinoma was significantly lower in group B (χ2 = 46.11, P < 0.05) than in group A. The proportion of tumor size and pathologic-TNM stage showed no significant difference between the two groups.
CONCLUSION: There is an increasing trend in the incidence of gastric cancer, but the malignance level of gastric cancer shows a decreasing trend in Yixing city.
