Abstract
-
Angiogenesis is essential for tumor growth and metastasis, however, the
prognostic value of neovascularization is undetermined. The aim of this study is to
evaluate the prognostic significance of microvessel density (MVD) and vascular
endothelial growth factor (VEGF) expression in breast carcinomas. An
immunohistochemical stains for CD 31 (DAKO) to estimate MVD and VEGF (Santa
Cruz) were done on 40 cases of invasive breast carcinoma. MVD was calculated as an
average count of vessels per 200 power field in the most vascularized areas. VEGF
expression was interpreted according to staining intensity and number of positive cells.
Mean MVD was 35, and MVD was not correlated with lymph node metastasis or
histologic grade, but high MVD (mean MVD>35) showed an increasing tendency in
cases with larger size, negative ER/PR, and positive cathepsin D. All of the cases
showed VEGF expression, but VEGF expression was not correlated with tumor size,
histologic grade, lymph node metastasis, ER/PR status, and cathepsin D expression.
These results suggest that MVD and VEGF expressions are not reliable prognostic
factors.
