Аннотация
The five-year survival rate of gastric cancer in China is close to those in European and North American countries but far lower than those in the Republic of Korea and Japan where national gastric cancer screening systems have been established. It is of great significance to build a high-quality gastric cancer screening system adaptive to China's national conditions. Due to the large number of people at risk of gastric cancer and the uneven distribution of medical resources, it is still difficult for China to carry out a nationwide gastroscopy screening program for gastric cancer. Gastric oral contrast ultrasonography (OCUS) is a promising, non-invasive tool for initial gastric cancer screening, offering a painless, radiation-free alternative. Based on two 2020 OCUS consensuses, this document analyzes national gastric cancer screening strategies and challenges to elaborate on the necessity, feasibility, and current problems of preliminary ultrasound screening in China. It details the key aspects of OCUS, including indications, contraindications, operator requirements, contrast agent standards, and essential scanning protocols. It also introduces the standardized ultrasound sections and the Stomach Ultrasound Report and Data System (Su-RADS) and proposes the relevant consensus opinions. After several rounds of discussions and voting by experts from multiple societies, a total of 17 consensus opinions have been formed on OCUS as a preliminary screening technique for gastric cancer, with the aim of standardizing the popularization of OCUS. In addition, the consensus calls for conducting nationwide multicenter prospective studies to improve the level of evidence and provide big data support for the construction of a preliminary gastric cancer ultrasound screening system that is in line with China's national conditions.
