| Core Tip |
The lymph node metastasis (LNM) risk in cases with undifferentiated-type early gastric cancer was evaluated and stratified using preoperatively as well as postoperatively evaluable factors. In preoperatively evaluable factors, the risk of LNM was predicted based on the size and depth and categorized into the low-risk group: mucosal cancer (m) and ≤ 2 cm, 0% (LNM incidence) (95%CI: 0-2.3), the moderate-risk group: m and > 2 cm, 5.6% (95%CI: 2.6-11.7); submucosal invasion (sm) and ≤ 2 cm, 6.0% (95%CI: 3.2-11.1), and the high-risk group: sm and > 2 cm, 19.3% (95%CI: 13.8-26.4). However, when the postoperatively evaluable factor of LI was included, cases with further lower or higher risk could be stratified even in the moderate- and high-risk groups. Some high-risk cases for surgery due to old age and concurrent disease could be reasonably followed-up after resection of the gastric lesion by endoscopic submucosal dissection. |
