Endometrium Cancer, Oxidative Stress
Conditions
Keywords
Early stage, thiol disulfide hemostasis, malignancy
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). References 1- Erel O, Neselioglu S.
