Study on the expression of vascular endothelial growth factor in patients with adenomyosis of the uterus / 中华妇产科杂志

ABSTRACT

Objective To investigate the role of angiogenesis and expression of vascular endothelial growth factor (VEGF) in the pathophysiology of adenomyosis of the uterus. Methods The study included 32 patients with histologically proven adenomyosis and 30 patients with asymptomatic leiomyoma of the uterus. Immunohistochemical staining was used to detect VEGF expression in different parts of the uterus. A computerized morphometric study on the VEGF expression was performed. Results The VEGF H-Score of glandular cells in the endometrium of adenomyosis uterus [proliferative phase (9.6?1.4), secretory phase (11.7?1.6)] was much higher than that of leiomyoma uterus [proliferative phase (8.3?1.7),secretory phase (10.2?1.5)] (P0.05). The VEGF H-Score of myometrium around the ectopic lesions [proliferative phase (9.5?1.3), secretory phase (8.7?1.3)] was higher than that of normal myometrium [proliferative phase (4.8?1.9), secretory phase (4.5?1.4)] (P
