A patient with a VEGF and endostatin producing gastrointestinal autonomic nerve tumour

Tumour associated neovascularisation has been characterised as chaotic and insufficient. This report details the results of the analysis of angiogenic factors in tumour cyst fluid, pleural fluid, and blood from a patient with a gastrointestinal autonomic nerve tumour. The tumour produced vascular endothelial growth factor and endostatin in large quantities, which may explain the dysfunctional angiogenesis and tendency to bleeding seen in this tumour type.
