Non-invasive neoplasia evolving into gastric cancer. Cases of gastric cancer detected after a follow up of more than 12 months
| Follow up (months)* | EGC | AGC | GC-nos | GCs 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. | |||||
| Low grade non-invasive neoplasia | 48 (21–85) | 5 | 1 | 2 | 8 |
| High grade non-invasive neoplasia | 30 (13–72) | 7 | 1 | 3 | 11 |
| Suspicious for invasive cancer | 30 | 1 | 0 | 0 | 1 |
