[Study on the operation process and construction standard of an esophageal cancer screening cohort study]

One of the most cost-effective measures in cancer prevention on cancer is to advocate to be aware of the disease, consciously changing negative behaviors, and taking the initiative to participate in regular physical checkup programs. Esophageal cancer is one of the malignant tumors accompanied by a heavy disease burden in China. Routine screening, early diagnosis, and treatment are the critical points of preventing and treating the disease. Cohort studies help understand the natural history and risk factors of esophageal cancer and identify high-risk groups of the disease. This paper intends to discuss the construction specifications of the multi-dimensional dynamic follow-up shared cohort for esophageal cancer by studying the risk factors, monitoring, and collecting biological sample information, providing references for developing a standardized and unified screening cohort research procedure, and necessary standards on esophageal cancer in the future.
