“Conclusion:Serum melatonin levels in PTC patients were higher than those in MNG and control groups, which may be associated with low malignancy of PTC; melatonin inhibits PTC metastasis, which exerts anti-PTC metastasis mainly through MT2 receptors.”
“Result:Serum melatonin concentration in patients with PTC was significantly higher than that in MNG patients and normal controls(P<0.05).”
