Early gastric cancers (EGC) may be subdivided into 2 groups by means o
f the use of mitotic index, apoptotic index and cell density: EGCs wit
h high cell turnover and low cell density, which show high cell dissoc
iation and, more frequently, lymph node invasion; EGCs with low cell t
urnover and high cell density. The same parameters discriminate among
intestinal type tumors, when separately considered from diffuse ones.
No correlation is noted of these 2 groups with transforming growth fac
tor-alpha, epidermal growth factor receptor and p53 expression, gross
type, entity of neoangiogenesis, and submucosal invasion.
