Quantitation and prognostic value of breast cancer angiogenesis: Comparison of microvessel density, Chalkley count, and computer image analysis

Abstract

In some studies of breast cancer, quantitation of immunohistochemically highlighted microvessel ‘hot spots’ has been shown to be a powerful prognostic tool. However, the antibody used, the number and size of the ‘hot spots’ assessed, and the stratification of patients into high and low vascular groups vary between studies. Furthermore, little is known about the relationship between microvessel density and other vascular parameters. These uncertainties and the laborious nature of the technique make it unsuitable for diagnostic practice. Both manual and computerized image analysis techniques were used in this study to examine the relationship between microvessel density and the vascular parame..
