Analysis of Clinicopathologic Characteristics of Gastric Cancer

Objective Western Inner Mongolia is a high risk area of gastric cancer. However, detailed clinical and pathological data of gastric cancer has been lacking. Our hospital is one of the largest gastric cancer diagnoses and treatment centers in western Inner Mongolia. This study was designed to investigate the characteristics of clinical data of patients with gastric cancer in Western Inner Mongolia at our hospital over the past eight years. Methods Data of 1548 cases of gastric cancer patients from 2007.01.01 to 2015.01.01 in our hospital was retrospectively analyzed for their clinical characteristics. Results Of the 1548 patients, 1251 cases (80.81%) were male and 297 (19.19%) were female, and the average age was 60.94±10.90 years old. The cancer location was mainly on the antrum, accounting for 40.76%. Different ages of gastric cancer location constituent ratio was different, and the difference was significant (χ2=39.836, P=0.000). Poorly differentiated adenocarcinoma was a major histological type, accounting for 46.58%. Different ages of histological classification and the differentiation constituent ratio was also different, and the difference was significant (χ2=67.300, P=0.000). There were 144 cases of early gastric cancer, accounting for 9.30%; 1404 cases of advanced gastric cancer, accounting for 90.70%. The majority pathologic type of advanced gastric cancers were Bormann Ⅲ(53.92%). Ⅲ+Ⅳ stage was a majority of TNM stage, accounting for 72.41％. Different ages of TNM stage was different, the difference was significant (χ2=9.013, P=0.029). Conclusion Advanced gastric cancer is the major type of patients with gastric cancer in Western Inner Mongolia. Gastric cancer has a higher incidence in older male patients. Poorly differentiated adenocarcinoma and cancer in antrum have a larger probability. Compared with older patients, there is higher occurrence of malignant cancer and earlier TNM stage in younger patients. Mongolian patients and Han patients showed no significant difference
