The role of angiogenesis in cancer growth and metastasis has been gaining much attention for decades. Recent clinical evidence supports this notion. The gradual increase in angiogenesis intensity with tumor progression in malignant melanoma has been reported. Abulafia et al. reported that increasing angiogenicity could be noted from simple hyperplasia, complex hyperplasia, atypical hyperplasia, and Stage IA endometrial carcinoma to invasive endometrial carcinoma. The investigators' research team has shown that incremental angiogenesis could be demonstrated in the tumorigenesis and the possibility of lymph node metastasis in endometrial malignancy. Besides, other growth factors such as vascular endothelial growth factor (VEGF), transforming growth factor- (TGF-), IL-6 and IL-8 have also been reported to correlate with the angiogenesis and the metastasis of endometrial cancer. It seems that tumor angiogenesis of endometrial cancer could be utilized as an important parameter to assess the disease severity of the endometrial cancer.
