T1 colorectal
e-T2 Score (Koyama / colorectal T1b vs T2)
0–11 points to distinguish deep SM invasion (T1b, ≥1000 μm) from T2 (muscularis propria) on endoscopy. Five-factor score from Koyama 2022 (GIE; derivation n=411). ≥7 points suggests T2.
Deep depression
>3-mm vertical depression (by evaluator observation)
Demarcated depressed area
Definite depression with a circumferential margin
Fold convergency
≥4 folds converging toward the tumor under adequate insufflation and extension
Erosion or white plaque
White covering not easily removed after lavage
Borrmann type 2 or 3
Type 2: ulcerated with sharply demarcated raised margins. Type 3: ulcerated infiltrating without definite limits
