Abstract

Neovascularization, the growth and formation of capillary blood vessels, is an essential component of solid tumor growth and a critical step in metastasis. Tumor associated macrophages (TAMs) have several functions related to tumor biology including growth, proliferative rate, stroma formation and dissolution, and neovascularization. The aim of this study was to define the TAM and microvessel density (MD) in human invasive breast carcionoma NOS and to correlate their values with lymph node status, tumor size, tumor grade and mitotic activity index (MAI), and, finally, to determine whether MD is connected with TAMs. A total number of 57 invasive breast carcinomas NOS were processed for immunohistochemical analysis using mAb to F-VIII to visualize endothelial cells and mAb to CD68 antigens for macrophages. Statistical analysis showed only a positive correlation between TAMs and MAI (p = 0.004). These results support the notion that intensity of tumor angiogenesis does not provide additional prognostic significance, while TAMs may play a positive role in breast cancer micro system since they regulate tumor proliferation.
