Angiogenesis plays a key role in tumour growth and the formation of metastases. Angiogenesis inhibitors and antivascular agents may prove useful in the treatment of breast cancer. A comprehensive characterization of the vasculature and perfusion of mammary tumours is a prerequisite for developing new specific drugs. We used sidestream dark field videomicroscopy to evaluate in vivo the vascular network of spontaneous mammary tumours in HER2/neu transgenic mice. The tumour masses showed higher vessel density compared with the healthy mammary gland (median (interquartile range) total vessel density 16.8 (13.4-20.5) vs 9.1 (8.1-10.9) mm/mm2, respectively; P 2. Sidestream dark field imaging is a versatile technique that may be useful for understanding the role of angiogenesis in the progression of breast cancer and its relationship with outcome. It may represent a valuable tool for dynamic monitoring of the effects of new anti-angiogenesis therapies.
