Abstract

In order to point out differences in the biological behaviour between early and advanced gastric carcinoma, their proliferative activity is evaluated on parafﬁn sections by silver staining of NOR particles and by immunohistochemical detection of PCNA. AgNOR particles were measured by a Leitz-Texture Analyzing System. The following variables were considered: nuclear area; area, number and percentage area of AgNOR; mean area of each AgNOR particle. The percentage of PCNA-positive nuclei was calculated. The results failed to show any signiﬁcant difference of EGC compared to AGC. The possibility that differences in biological behaviour, other than the proliferative activity, could exist between EGC and AGC, is discussed.

Keywords : AgNOR, early gastric cancer, PCNA, proliferative activity
