[Angiogenesis and endometrial carcinoma. Correlations with blood flow analysis by transvaginal color Doppler ultrasonography]

Neoangiogenesis is a basic event in the evolution and spread of several solid neoplasms. Angiogenesis is an active phenomenon in physiological endometrium in the reproductive age and seems to disappear in postmenopause. Endometrial hyperplasia and adenocarcinoma are associated with signs of angiogenetic activity. The factors promoting angiogenesis in endometrial carcinoma are still unknown. Similarly it is not possible to recognize which endometrial carcinoma is potentially angiogenetic, but a relationship between angiogenesis and early metastatic spread has been established. Angiogenesis is definitely a late component of invasive tumour, but an early angiogenetic behaviour of some neoplastic clones, that could be a main prognostic factor for endometrial carcinoma is hypothesized.
