| Tumour type | Tumour type | Specimen type |
| Presence of associated epithelial dysplasia when identified | Assessment of minimum depth of invasion | Length of specimen |
| Assessment of minimum depth of invasion, identification of submucosal invasion when this is present in the biopsy (level, not measurement) | Presence of associated epithelial dysplasia when identified | Site of tumour |
| Identification of submucosal invasion when present | Macroscopic appearance of tumour | |
| Assessment of completeness of excision of both dysplastic and malignant components | Dimensions of tumour | |

| Invasive tumour type | ||
| Invasive tumour grade of differentiation | ||
| Character of the invasive margin that is expansile or infiltrative gastric cancer | ||
| Serosal involvement | ||
| Depth of invasion | ||
| Vascular invasion | ||
| Number of regional lymph nodes examined | ||
| Number of involved regional lymph nodes | ||
| Number and site(s) of distant (non-regional) lymph nodes submitted and number involved (M1) | ||
| Distance to circumferential margin and status of this margin (in oesophageal cancer <1 mm regarded as involved). Local dissection of lymph nodes may compromise the estimation of the circumferential margin, but the distance to the remaining margin should be stated | ||
