Image Risk Assessment of the Thyroid Cancer Model Based on Discriminant Analysis and the Value of TAP and CEA Combined Detection

Abstract

The incidence rate of thyroid disease is increasing rapidly worldwide, and the number of thyroid patients is increasing. In this study, serum TAP (tumor abnormal protein) and CEA (carcinoembryonic antigen) were used to detect patients with thyroid nodules of class IV and above to explore the value of serum TAP combined detection of CEA in the risk assessment of thyroid cancer. In this paper, 400 patients with thyroid nodules above class IV diagnosed by physical examination in our hospital health management center from January 2019 to June 2021 were included in the study. Combined with the pathological test results, the patients were divided into risk groups. At the same time, different groups of serum TAP and CEA levels were detected by aggregation and electrochemiluminescence methods, and serum TAP and CEA levels were analyzed according to the pathological diagnostic indicators of CEA levels. The results showed that the levels of serum TAP and CEA in patients with thyroid cancer were significantly higher than those in patients with benign thyroid diseases, and the difference was statistically significant ( $P$  < 0.05). The sensitivity, specificity, and AUC under the ROC curve area of serum TAP were 85.25%, 85.06%, and 0.605, respectively. The sensitivity, specificity, and AUC under the ROC curve area of serum CEA were 89.85%, 88.00%, and 0.627, respectively. The sensitivity, specificity, and AUC under the ROC curve area of serum TAP combined with CEA were 96.84%, 96.79%, and 0.915, respectively. Therefore, the combined detection of serum TAP and CEA has a high early screening value in thyroid cancer.
