NCT03756480

Brief Summary

This study will test the hypothesis that the molecular changes present in ectopic endometriosis lesions correlate with progesterone-resistant disease (using the criteria defined in this study) and are present in matched eutopic endometrium.

Outcome Measures

Primary Outcomes (1)

  • Number of somatic cancer driver mutations in progesterone-resistant versus progesterone-sensitive endometriosis lesions.

    Digital droplet PCR will be used to identify somatic cancer-driver mutations with the presence of at least one of KRAS or ARID1A or PIK3CA or PPP2R1A cancer-driver mutations to assess any difference between progesterone-resistant endometriosis and progesterone-sensitive endometriosis.

    Six month

Secondary Outcomes (2)

  • Number of cancer driver mutations in eutopic versus ectopic endometrial tissue in control versus diseased subjects

    Six month

  • Difference in DNA methylation PCR profile of endometriotic lesions in ectopic versus eutopic endometrium in control versus diseased subjects.

    One month

Study Arms (2)

Case Group

Clinical or surgical diagnosis of Endometriosis, patients undergoing surgical management 100 participants
