Thiol Disulfide Balance in Cervix Cancer

Completed

• Conditions: Cervix Cancer; Oxidative Stress

• Registration Number: NCT04258553
• Lead Sponsor: Muğla Sıtkı Koçman University

Brief Summary

The aim of this research is to evaluate thiol-disulfide balance in cervix cancer patients

Detailed Description

To date various oxidative stress parameters were studied in patients with cervix 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).
