[Application and progress of artificial intelligence technology in gastric cancer diagnosis and treatment].

Artificial intelligence (AI) is one of the most rapidly evolving fields in biomedicine during the past decade. Represented by radiomics, machine learning and deep neural network, AI has been increasingly favored by researchers due to its ability to obtain feature information and discover the potential relationship between data and medical outcomes from high-throughput medical data. The incidence and mortality of gastric cancer (GC) has remained high in China. Through combining AI technology with medical examination such as endoscopy, imaging, pathological examination and sequencing, clinical researchers have made great progress in the auxiliary diagnosis, disease staging, prognosis and curative effect prediction of patients with GC. Although the intervention of AI in the medical industry has greatly improved the effective utilization of high-throughput data and accelerated the intelligent process of disease diagnosis and treatment, a number of problems has been raised in medical ethics, patient privacy and the legal status of medical AI at the same time. In the future, rational planning and management of AI technology will provide a strong impetus to promote the development of medicine and reshape the medical industry.人工智能（AI）是生物医学领域过去十年中发展最快的新技术领域之一。以影像组学、机器学习和深度神经网络等为代表的AI技术，因其能从医学资料中高通量地获取特征信息、分析特征数据并挖掘揭示数据与医疗结果之间的潜在联系，愈发被研究者青睐。胃癌在我国具有较高的发病率和死亡率，而将AI技术和内镜、影像、病理及测序分析等相结合的检查手段，已经在胃癌的辅助诊断、疾病分期和预后以及疗效预测等方面取得了重要的进展。AI在医疗行业中的应用极大提升了高通量数据的有效利用率，加速了疾病诊疗的智能化进程，但同时也在医学伦理、患者隐私和医疗AI的法律主体地位等方面产生了许多问题。未来，合理地规划和管理AI技术，有望为推动医学发展及重塑医疗行业提供强大的动力。.
