Background : Angiogenesis, which is essential for tumor growth, is known to occur in the
extravascular stroma. However, vascular structures were noted in intravascular tumor emboli
in surgical specimens. This prompted our investigation of the frequency and morphology of
angiogenesis in tumor emboli. Methods : Hematoxylin-eosin stained specimens were reviewed
for tumor emboli, in 21 cases of stomach adenocarcinoma and 22 cases of colon adenocarcinoma.
The cases were examined with immunohistochemistry using antibodies against
epithelial antigen (cytokeratin), endothelial antigens (CD31, CD34), lymphatic endothelial
antigen (D2-40), and proliferation-associated antigen (MIB1). Results : Endothelial cells
were observed in 16 tumor emboli among four (19.1%) of the 21 cases of stomach adenocarcinoma
and in 32 tumor emboli among four (18.2%) of the 22 cases of colon adenocarcinoma.
The endothelial cells in the tumor emboli showed papillary ingrowth from the vessel
wall, formation of vascular lumens, scattered distribution, or surface coating of the emboli.
Some of the endothelial cells in the tumor emboli were D2-40-positive, and some were MIB1-
positive. Conclusions : These findings demonstrated that angiogenesis occurs in intravascular
tumor emboli as well as in the extravascular stroma. Angiogenesis in the tumor emboli
may reflect an active process and may facilitate tumor growth.
