Metastasizing intramucosal gastric carcinomas. Well differentiated type and proliferative activity using proliferative cell nuclear antigen and Ki-67

Abstract

The potential for NI in IMGCs seems to be related closely to tumor size, the presence of poorly differentiated components, and, particularly in the W-type IMGC, the LI that are demonstrated immunohistochemically with Ki-67 and/or PCNA.
