Table 3 Updated evaluation of curability after endoscopic submucosal dissection in Japanese gastric cancer treatment guidelines 2018
Updated evaluation of curability after endoscopic submucosal dissection | |
eCuraA | En-bloc resection, predominantly differentiated adenocarcinoma, pathological mucosal cancer (pT1a), HM0, VM0, Ly0, V0 |
UL0 (regardless of size) | |
UL1, under 3 cm in diameter | |
If size of undifferentiated component is > 2 cm, tumor is diagnosed as eCuraC-2 | |
eCuraB | En-bloc resection, HM0, VM0, Ly0, V0 |
UL0, under 2 cm in diameter, predominantly undifferentiated adenocarcinoma, pathological mucosal cancer (pT1a) | |
UL1, under 3 cm in diameter, predominantly differentiated adenocarcinoma, pathological submucosal cancer within 500 µm (pT1b1) | |
If there is an undifferentiated component in the submucosal layer, tumor is diagnosed as eCuraC-2 | |
eCuraC-1 | Lesion meeting criteria of eCuraA or eCuraB except with positive lateral margin or non–en-bloc resection. |
eCuraC-2 | The lesion meets none of eCuraA, eCuraB, or eCuraC-1 |
