  1. aLocation and histological differentiation of the tumours were determined according to the Japanese Classification of Gastric Cancer 2nd edition (2001). tub1= well-differentiated tubular adenocarcinoma, tub2= moderately differentiated tubular adenocarcinoma.
  2. *There was significant difference between mucin phenotypes and location of EGC (P=0.007, Fisher's test).
