To investigate the proliferative activity and relation to malignancy using proliferating cell nuclear antigen(PCNA)-labeled indices and number of silver stained nucleolar organizer regions(AgNORs) per cell in gastric cancer versus precancerous lesion, PCNA immunohistochemistry and AgNORs silver staining was performed in cases of gastric cancer(30 cases), flat adenoma(5 cases), adenomatous polyp(5 cases), and control(15 cases).
