入选标准

  • Individuals who are 20 years of age or older at the time of endoscopic image acquisition.
  • Individuals who can provide early gastric cancer tissue suitable for pathological diagnosis by a pathological evaluator.
  • Individuals who can provide images that meet the following criteria for endoscopic images:
  • Images captured using White Light mode
  • Vertical resolution of 700 pixels or more and horizontal resolution of 800 pixels or more (image area)
  • Images captured using an Olympus or Fujifilm endoscope
  • Five or more images per lesion
  • Suitable for deep depth diagnosis, as shown below
  • The entire gastric tumor is generally visible (without using close-up or magnifying endoscopy, etc.)
  • The details of the tumor's shape can be observed (without moving the lens too far from the tumor)
  • Sufficient insufflation is performed.

排除标准

  • The following images are excluded
  • Images that do not show the gastric tumor (such as normal areas)
  • Images taken after treatment such as biopsy or clipping, or images with severe bleeding
  • Images that show foreign objects such as food residue
  • Blurred or unclear images due to poor focus or other factors
  • Images that only show a portion of the lesion due to magnifying endoscopy or close-up photography
  • Individuals who have undergone gastric resection or gastric tube reconstruction at the time of endoscopic image acquisition or specimen collection.
  • Individuals with lesions extending to the esophagus or duodenum at the time of endoscopic image acquisition or specimen collection.
  • Individuals with a history of chemotherapy or radiation therapy to the upper abdomen within the year prior to the target endoscopic examination.
  • Patients who have refused to participate in the study.
