Brief Summary:
Purpose Neo-angiogenesis is necessary for adhesion and invasiveness of endometriotic lesions in women affected by endometriosis VEGF is one of the major components of angiogenesis and is part of the major pathway TF-PAR-2-VEGF that leads to neo-angiogenesis SP1 is a transcriptional factor that has lately been studied for its crucial role in angiogenesis via a distinct pathway We hypothesize that by blocking angiogenetic pathways we can repress endometriotic lesions GnRH-agonists are routinely used especially pre-operatively in endometriosis It would be interesting to clarify which angiogenetic pathways are affected and pave the way for further research over anti-angiogenetic effects on endometriosis
Methods We used qRT-PCR to study mRNA expression levels of TF PAR-2 VEGF and SP1 in endometriotic tissues of women who underwent surgery for endometriosis and received GnRH-a leuprolide acetate preoperatively

Detailed Description:
The subjects in this study were women of reproductive age From September 2015 to December 2022 sixty women with known endometriosis stage 2 and 3 were recruited Their mean age was 38 years They were nulliparous and had a mean BMI of 27 kgm2 The ovarian endometrioma present in all the participants was diagnosed by ultrasonography andor magnetic resonance imaging
This was a prospective randomized follow up study with analysis of ovarian samples derived from GnRH agonists-treated and non-treated women before surgery The randomization was performed by accessing a central internet-based randomization program The random allocation sequence and the assignment of the participants to interventions were made by 2 of the authors AK and SK
After enrollment patients were divided into 2 groups During laparoscopy biopsy specimens of the ovarian endometrioma were collected The staging of endometriosis was based on the rASRM classification system In group B surgery was performed during the proliferative phase of the menstrual cycle All biopsy specimens were collected in accordance with the guidelines of the Declaration of Helsinki and with the approval of the ethical committee of the General University Hospital of Patras Informed consent was obtained from all women
