| pTis/M | VM0, HM0, complete resection → surveillance |
| VM1 | Incomplete endoscopic resection → strongly recommend surgery |
| HM1 | Positive horizontal margin → consider additional resection |
| ① Vertical margin | VM0 (complete resection) |
| Horizontal margin | HM0 (negative) |
| ② Histology | Papillary or tubular adenocarcinoma |
| ③ SM invasion | <1000 µm |
| ④ Ly | Ly0 (absent) |
| ④ V | V0 (absent) |
| ⑤ Budding | BD1 |
| Criteria not met | Consider additional resection (low recommendation); balance LNM risk and patient factors |
