Abstract:
Oesophageal cancer and gastric cancer are the most common malignant tumors of the upper gastrointestinal tract.As a country with a high incidence of oesophageal cancer and gastric cancer,most pa-tients are already in the progressive stage when diagnosed,and their 5-year survival rate is less than 20％.If early diagnosis and early treatment of upper digestive tract tumors can be achieved,the 5-year survival rate will exceed 90％,which can significantly improve the prognosis of the patients.Optical coherence tomography (OCT) is a non-traumatic,high-resolution,non-invasive optical imaging technique that provides microanatom-ical images of biological tissues at millimetre depth and micron resolution.On the one hand,it can be used for rapidly and non-invasively detecting the tissues,organs,blood vessels or glands in lesions.On the other hand,it can also identify the optical features of early tumor lesions,which has an important significance in the early diagnosis of upper gastrointestinal tract tumor.This paper reviewed the principle and classification of OCT,summarizes the latest application progress of OCT in upper gastrointestinal early cancer,and discussed the po-tential of OCT combined with artificial intelligence technology in deep learning.
