摘要
Gastric cancer(GC)is a major cancer worldwide,with high mortality and morbidity.Endoscopy,important for the early detection of GC,requires trained skills,high-quality technologies,surveillance and screening programs.Early diagnosis allows a better prognosis,through surgical or curative endoscopic therapy.Magnified endoscopy with virtual chromoendoscopy remarkably improve the detection of early gastric cancer(EGC)when endoscopy is performed by expert endoscopists.Artificial intelligence(AI)has also been introduced to GC diagnostics to increase diagnostic efficiency.AI improves the early detection of gastric lesions because it supports the non-expert and experienced endoscopist in defining the margins of the tumor and the depth of infiltration.AI increases the detection rate of EGC,reduces the rate of missing tumors,and characterizes EGCs,allowing clinicians to make the best therapeutic decision,that is,one that ensures curability.AI has had a remarkable evolution in medicine in recent years,moving from the research phase to clinical practice.In addition,the diagnosis of GC has markedly progressed.We predict that AI will allow great evolution in the diagnosis and treatment of EGC by overcoming the variability in performance that is currently a limitation of chromoendoscopy.
