Evaluation of Thiol Disulfide Balance in Stage 1 Endometrium Cancer

Completed

• Conditions: Oxidative Stress; Endometrium Cancer

• Registration Number: NCT04175067
• Lead Sponsor: Muğla Sıtkı Koçman University

Brief Summary

The purpose of this study is to investigate thiol-disulfide balance in early stage endometrium cancer patients.

Detailed Description

To date various oxidative stress paramaters were studied in patients with endometrial cancer, however dynamic thiol disulfide hemostasis has not been previously investigated.

The thiol-disulfide balance in the circulation will be measured by the automated system created by Erel \& Neselioglu(1).
