Evaluation of a Number of Blood Biochemical Markers after Radioiodine Therapy in Papillary Thyroid Cancer Patients

Background: This study aimed to assess several biochemical and oxidative stress parameters before and after radioiodine therapy in patients with well-differentiated thyroid cancer who consumed a low iodine diet and withdrawal of levothyroxine after total thyroidectomy. Methods:We enrolled 40 candidates for radioiodine therapy. Blood sampling was performed prior to as well as 72 h after consumption of 125-200 mCi of 131I. Total protein, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and creatinine were measured. Oxidative stress parameters that included malondialdehyde and protein carbonyl levels were also assessed. Results: There were significantly decreased total protein, creatinine, aspartate aminotransferase, and alanine aminotransferase levels (P
