Evaluation of Metastatic Potential of Gastric Tumors by Staining for Proliferating Cell Nuclear Antigen and Chromosome 17 Numerical Aberrations

Background: Aberrations in chromosome 17 are important in carcinogenesis. We recently reported that numerical aberrations in chromosome 17 were associated with tumor progression in gastric cancer. The aim of this study was to determine the biological characteristics of gastric tumor cells with chromosome 17 numerical aberrations.
