@entity5 angiogenesis is required for @entity5 growth and @entity3 . A statistically significant correlation has been demonstrated between prognosis and the microvessel density (a measure of @entity5 angiogenesis) of solid tumors, particularly of the breast and prostate, and @entity706 . The aim of this study was to establish whether a correlation exists between vascular density and the malignant category of @entity1893 ( @entity1893 ) defined by two classification systems (Kiel and Working Formulation). We also tested whether @entity1373 ( @entity1373 ) and @entity706 ( @entity706 ) behave as new vessel stimulating conditions. Eighty-nine @entity1893 lymph node biopsies were reviewed and categorized according to the Kiel Classification and Working Formulation. Twelve @entity706 were also selected and compared to 12 @entity1373 biopsies. Vessels were highlighted by immunostaining with anti-Factor VIII antibody and quantified both by counting higher vascular density fields and by estimating the proportional vascular area. The results showed a statistically significant difference between low and high grade @entity1893 , when classified in either the Working Formulation (p=0.0015) or the Kiel Classification (p=0.002). No differences were found in vessel counts between Working formulation intermediate and high @entity706 . Vascular density is similar when @entity1373 and @entity706 interfollicular areas are compared.
