ABSTRACT

Objective To detect the level of the serum estradiol-2 (E_2), tumor necrosis factor-alpha (TNF- α) and vascular endothelial growth factor (VEGF) in patients with endometriosis (EMS) and explore their clinical significance. Methods Fifty-nine EMS patients from January 2006 to January 2009 were selected as EMS group and 60 normal women were selected as control group. The serum E_2,TNF-αand VEGF in EMS group 24 h pre-operation, 7 d post-operation and 6 months after operation were detected, and compared with control group. Results The levels of the serum E_2[(216.5 ± 59.7) ng/L],TNF- α [(30.4 ± 17.5) μg/L]and VEGF [(250.7 ± 88.7) ng/L]in EMS group pre-operation were significantly higher than those in control group [(100.2 ± 33.2) ng/L, (11.2 ± 3.6) μg/L, (103.2 ± 49.2) ng/L]and post-operation [(121.3±44.6) ng/L, (13.4 ± 6.2) μg/L, (153.9 ± 58.7) ng/L](P < 0.01). But there was no significant difference between control group and post-operation of EMS group (P > 0.05). The levels of the serum E_2 [(316.5 ± 77.6) ng/L],TNF-α [(51.1 ± 12.3) μg/L]and VEGF [(305.1±69.7) ng/L]with stage Ⅲ-Ⅳ in EMS group were higher than those in control group or those with stage Ⅰ - Ⅱ [(170.7±48.2) ng/L, (25.8 ± 10.1) μ g/L, (169.2 ± 36.1) ng/L](P < 0.05 or < 0.01). The levels of the serum E_2,TNF- α and VEGF with stage Ⅰ - Ⅱ in EMS group were also higher than those in control group (P < 0.05). Nine patients recurred at 6 months after the operation. The levels of the serum E_2[(187.8 ± 46.7) ng/L],TNF- α [(23.9 ± 9.5) μg/L]and VEGF [(185.3 ± 57.4) ng/L]of the recurred EMS patients stepped up significantly higher than those of the non-recurred EMS patients [(112.7±30.3) ng/L, (13.2±4.7) μg/L, (116.4±30.3) ng/L](P < 0.01). While there was no significant difference between control group and non-recurred EMS patients (P >0.05). Conclusions The serum E_2,TNF-αand VEGF may play important roles in the development of the EMS. And the detection of the serum E_2,TNF-αand VEGF is useful to judge the patient's condition and the prognosis of the EMS.
