Tumour typeTumour typeSpecimen type
Presence of associated epithelial dysplasia when identifiedAssessment of minimum depth of invasionLength 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 identifiedSite of tumour
Identification of submucosal invasion when presentMacroscopic appearance of tumour
Assessment of completeness of excision of both dysplastic and malignant componentsDimensions of tumour
Assessment of vascular invasionDistance to margins
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
Status of proximal and distal margins
Other relevant pathology (Barrett's oesophagus, background dysplasia, chronic gastritis, Helicobacter pyloristatus, etc.)
TMN staging system, including R status
