Tumour epithelial expression levels of endocannabinoid markers modulate the value of endoglin-positive vascular density as a prognostic marker in prostate cancer

► Angiogenesis and endocannabinoid markers show associations in prostate cancer. ► The markers studied were endoglin, von Willebrand factor, CB1 receptors and FAAH. ► At high CB1 or FAAH tumour expression levels, endoglin was a prognostic biomarker. ► At low CB1 or FAAH tumour expression levels, this property of endoglin was lost.
