Outcome Measures
Primary Outcomes (1)
Accuracy, Sensitivity, and Specificity for Differentiating Neoplastic and Non-neoplastic Lesions
For this training, patients were consecutively enrolled until a total of 45 target and non-target lesions were obtained.

Biospecimen
if the lesion is neoplastic or sm deeper cancer, we just take biopsy.If the lesion is adenomatous or sm1-2 cancer,we do polypectomy, EMR or ESD to get the specimen.
