Multicenter Prospective Cohort Study of Risk Factors for Gallbladder Cancer

Gallbladder cancer is the most common malignant biliary tract tumor. The main risk factors for gallbladder cancer include gallstones, gallbladder polyps, gallbladder adenomas, chronic inflammation of the gallbladder, etc. However, recently, there is still a lack of evaluation data on relevant risk factors. Therefore, on the basis of large-scale epidemiological investigations, large-scale prospective studies are needed to further clarify the level of risk factors associated with gallbladder cancer. With the development of modern imaging technology and deep understanding of gallbladder diseases, the detection rate of benign gallbladder lesions (cacerous polyps, gallbladder adenomyosis, gallbladder adenoma, gallstones, etc.) has increased year by year, and some benign gallbladder lesions can pass A series of pathophysiological processes have gradually evolved into gallbladder cancer. This study aimed to establish a prospective cohort of benign gallbladder disease, to explore the correlation, intervention time and socioeconomic benefits of benign gallbladder disease and gallbladder cancer. In order to further understand the current trend and diagnosis and treatment of benign gallbladder disease in China, the Chinese Society of Surgery Branch of the Chinese Society of Surgery will launch a national epidemiological survey of gallbladder cancer (2018). This study will provide a more detailed basis for the diagnosis and treatment of benign gallbladder disease in China.
