title: Histological risk markers for non-cardia early gastric cancer. Pattern of mucin expression and gastric cancer.
abstract: There are limited data regarding the prognostic value of the pattern of mucin expression in IM. To examine the role of the type of IM and pattern of mucin expression in IM as histological risk markers of gastric cancer, 80 patients with a history of endoscopic mucosal resection (EMR) for early gastric cancer and 80 sex and age-matched controls were studied. Serum levels of pepsinogen (PG) were measured by RIA, and MUC2, MUC5AC and MUC6 were evaluated immunohistochemically. There is a significant association between types of IM and atrophic scores or PG levels. The most incomplete IM (type II and III) preserving gastric mucin is the gastric and intestinal mixed (GI) type, whereas the complete type is the intestinal (I) type especially in the corpus lesser curve. Gastric cancer was most significantly associated with incomplete IM in the corpus lesser curve (OR=6.4; 95% CI, 2.0-21, p=0.002). Asynchronous multiple lesions were associated with incomplete IM in the corpus greater curve (OR=4.8; 95% CI, 1.4-16, p=0.01). Classification of IM obtained using fixed-point biopsy samples may enhance the ability of surveillance programs to detect patients at increased risk of gastric cancer.
