Abstract
Aims and Background
The oxidation of protein plays an essential role in the pathogenesis of an important number of degenerative and cancer diseases, which is now widely recognized. The aim is to examine advanced oxidation protein products (AOPPs), lipid peroxidation products malondialdehyde (MDA), and ferrous oxidation in xylenol orange (FOX) in blood samples of papillary thyroid cancer patients compared with healthy controls to determine the oxidation status and the change after thyroidectomy.
Methods
Thirty-five female thyroid cancer patients who underwent total thyroidectomy and 39 female control subjects were included into this study. Prethyroidectomy and postthyroidectomy, AOPP, FOX, and MDA levels were studied.
Results
Prethyroidectomy AOPP, FOX, and MDA levels were significantly higher compared to control (P < .05). In postthyroidectomy AOPP, FOX, and MDA levels were significantly decreased compared with prethyroidectomy levels (P < .05). However, postthyroidectomy levels on the 20th day were still significantly higher, compared to control subjects (P < .05).
Conclusion
In conclusion, all of AOPP, FOX, and MDA levels that are markers of protein oxidation and lipid hyperoxidation may induce thyroid cancer development and begin to decrease after thyroidectomy.
