However, the clinical significance of vimentin expression in carcinomas is not well understood. The aim of this study was to clarify the significance of vimentin-positive gastric cancer (GC). Patients and Methods: A total of 265 GCs were examined by immunofluorescent staining with antibodies against vimentin and carcinoembryonic antigen. GCs were determined to be vimentin-positive when cells were positive for both vimentin and carcinoembryonic antigen staining. Results: A total of 86 (32%) of 265 GCs were vimentin positive. There was a statistically significant correlation between vimentin-positive GCs and advanced clinical stage (p<0.001), macroscopic scirrhous-type (p<0.001), histological diffuse-type (p<0.001), lymph node metastasis (p=0.008) and lymphatic invasion (p=0.013). The prognosis of patients with vimentin-positive GCs was significantly (p<0.001) worse than that with vimentin-negative GCs. Conclusion: Vimentin expression might contribute to the high invasive phenotype of GC, and may be a useful biomarker to determine the biological aggressiveness of GC.
