Non-invasive neoplasia evolving into gastric cancer. Cases of gastric cancer detected after a follow up of more than 12 months

Follow up (months)*EGCAGCGC-nosGCs developing during follow up
*Values are mean (range). Duration of follow up is the time that elapsed between the initial endoscopy procedure and the histological diagnosis of gastric cancer.
EGC, early gastric cancer (that is, pathological stage I); AGC, advanced gastric cancer (that is, pathological stages II–III); GC-nos, gastric cancer of unknown pathological stage.
