EGFR and neoplasm: Evaluated by IHC staining intensity, moderate or strong EGFR protein expression was associated with the depth of tumour invasion (pT3–pT4 versus pT1–pT2; Fisher’s exact test, p = 0.029); OR 2.15, 95 % CI: 1.11–4.17), but did not associate with tumour location (distal oesophagus/GOJ/cardia versus gastric corpus/antrum/pylorus; Fisher’s exact test, p = 0.054).
