Abstract:
Objective:To use inductively coupled plasma mass spectrometry(ICP-MS)to screen biomarkers of element omics of thyroid cancer,and to establish a risk assessment model of element omics of thyroid cancer,so as to provide a basis for the diagnosis and treatment of thyroid cancer.Methods:A total of 200 patients with thyroid cancer who admitted to Beijing Tongren Hospital from February to November 2020 were selected as the thyroid cancer group,and 50 healthy volunteers who underwent physical examinations at hospital during the same period were selected as the healthy control group.The total amount of 28 trace elements,including iodine(I),calcium(Ca),iron(Fe),nickel(Ni),copper(Cu),zinc(Zn),selenium(Se),antimony(Sb),etc.,in their serum were determined by ICP-MS.The content of trace element,thyroid function,free triiodothyronine(FT3),free tetraiodothyronine(FT4),triiodothyronine(T3),tetraiodothyronine(T4),and thyroid volume of ultrasound examination of were analyzed,and then,a risk assessment model of elemental omics of thyroid diseases was established.Results:There were statistically significant differences in the contents of eight trace elements,including I,Ca,Fe,Ni,Cu,Zn,Se and Sb between the thyroid cancer group and the healthy control group(U=2.601,1.972,2.607,2.611,2.603,2.605,2.601,2.605,P<0.05),respectively.The I,Cr and Mn levels of female patients with thyroid cancer appeared increase,while there were significant differences in I,Mn,Fe,Ni,Cu,Zn,Se and Sb contents of male patients between the thyroid cancer group and the health control group(U=2.601,2.608,2.603,2.602,1.973,2.603,2.601,2.602,P<0.05),respectively.In thyroid cancer group,the FT3,FT4,T3,T4 correlated with I content(r=06209,0.5116,0.557,0.5923,P<0.05),respectively.There were correlations in the concentrations between Fe and Zn,between Cr and Mn,between Ca and Zn,between Se and Fe,and between Zn and Se in the thyroid cancer group(r=0.5523,0.5528,0.7158,0.5699,0.6371,0.5420,P<0.05),respectively.High concentrations of I and Mn were risk factors for thyroid cancer.The specificity and sensitivity of the risk assessment model of elemental omics of thyroid cancer were all larger than 95%.Conclusion:In patients with thyroid cancer,both of the serum Ca of female patients and serum Fe of male patients play important role besides cobalt(Co),Ni,Cu,Zn,Se and Sb play role,which can provide basis for the diagnosis and treatment of thyroid cancer.The risk assessment model based on elemental omics of thyroid cancer has favorable diagnostic performance.
