Core Tip

Core tip: Gastric cancer is an important public health burden in China (especially in northwest of China). The Hehuang valley part of the ancient Silk Road, is located in the northeast of the Qinghai-Tibetan Plateau. As an important population center on the Silk Road, a systematic clinical epidemiological study of gastric cancer is necessary. We conducted a clinical epidemiology study of gastric cancer in the Hehuang valley. Significant differences were observed for race, sex, and age of patients with gastric cancer in the Hehuang valley. Dietary habit was an important factor contributing to gastric cancer.
