Forty cases of infiltrating duct carcinoma of the breast were examined
immunohistochemically for expression of TGF-¥â and angiogenesis in order to analyze
significant correlation with prognostic parameters including tumor size, axillary lymph
node metastasis, clinical stage, histologic grade, estrogen receptor and progesterone
receptor status. The TGF-¥â expression was observed in tumors center and advancing
edges of tumors. To determine microvessel density for angiogenesis, we stained
endothelial cells for Factor ¥· related antigen and counted microvessel within tumor. The
results were as follows: 1) The strong immunohistochemical expression of TGF-¥â and
higher counts of microvessels were observed in advancing edges of tumors (p<0.05). 2)
The TGF-¥â expression in the advancing edges of tumors was closely related to clinical
stage and presence of axillary lymph node metastasis (p<0.05). 3) The mean microvessel
counts were significantly higher in tumors from patients with axillary lymph node
metastasis and increased with increasing clinical stage (p<0.05). 4) The TGF-¥â
expression was not related to histologic grade, estrogen receptor and progesterone
receptor status(p>0.05). Therefore, the results suggested that the TGF-¥â expression
and angiogenesis in infiltrating duct carcinoma of the breast may play an important part
in prognostic factors, closely related to the lymph node metastasis and clinical stage.
