Purpose: Angiogenesis is an essential component of tumor growth and proven to be a
prognostic factor in breast, cervix, prostate carcinoma and melanoma. This study was
designed to define the relationship of microvessel density with overall survival,
clinicopathologic data and with other reported prognostic factors in gastric carcinoma.
Methods: We studied resected tumor specimens from thirty-two patients with gastric
carcinoma who underwent gastrectomy at Ewha Women's University Hospital from
January, 1989 to December, 1991. Specimens were investigated by staining with a
monoclonal antibody against factor VIII-related antigen, which was localized to vascular
endothelium. Correlation between the microvessel count(¡¿200), various clinicopathologic
factors, EGFR and p53 were studied.
Results: The microvessel count was increased with higher histologic staging. The
microvessel count was significantly higher in group with lymph node metastasis than in
those without lymph node metastasis(60.7 vs 27.4, p=0.02). In patients with high
microvessel count( 30), overall survival time was shorter than in those with low
count(<30), but insignificant statistically(p>0.05). The microvessel count was higher in
group with recurrence than in those without recurrence(48.1 vs 33.2, p=0.05).
Conclusion: Microvessel count may be a prognostic indicator in gastric carcinoma but
larger scale study should be followed.
