GOJ, gastro‐oesophageal junction.

Well, Mod, Poor corresponds to the tumour differentiation; Mod, moderately differentiated.

R0, completed excised; R1+, incompletely excised.

*Classed as pN1+ as it was not always clear from the pathology report whether these were designated oesophageal or gastric for staging purposes.
