NCT01809561

Brief Summary

The purpose of the study is to assess the telomere array of different endometriosis tissue and endometrium from women with endometriosis compared to healthy women. Our hypothesis is that telomere shortening and high telomerase activity will be found in tissues from women with endometriosis.

Outcome Measures

Primary Outcomes (1)

  • characterize the telomeres array and telomerase levels and other characteristics for genomic instability such as spontaneous aneuploidy in endometriosis tissue.

    the tissue sample will colect at time of surgery

Study Arms (2)

endometriosis

The study group will consist of women with suspected endometriosis facing surgical treatment

Procedure: tissue biopsy during surgical treatment

no endometriosis

The control group will consist of healthy women facing gynecologic surgery for different indication

Procedure: tissue biopsy during surgical treatment

Interventions

The samples collected will test for histological diagnosis of endometriosis and verification tests will be done to characterize the telomeres array and telomerase levels and other characteristics for genomic instability such as spontaneous aneuploidy.

Also known as: endometriosis tissue biopsy only study group, endometrial tissue biopsy
