Correlation between Ultrasonic Parameters and Malignant Degree of Thyroid Cancer

Abstract

Abstract: Objective To investigate the correlation between ultrasonic parameters and malignant degree of thyroid cancer. Methods A total of 70 patients diagnosed with thyroid cancer in Second Xiangya Hospital of Central South University from January 2019 to January 2019 to January 2022 were selected as the malignant group, and other patients with benign thyroid nodules treated in the same period were selected as the benign group. The ultrasound image features and ultrasound related parameters were compared to analyze the diagnostic value of ultrasound on the malignancy of thyroid cancer. Results The number, boundary, shape, margin, capsule, posterior echo and calcification of lesions in malignant group and benign group were significantly different (P<0.05); The time difference of the first peak and the slope of ascending branch in malignant group were significantly higher than those in benign group (P<0.05); Spearman correlation analysis showed that the number, border, shape, edge, capsule, posterior echo, calcification, time difference of the first peak and the slope of ascending branch of thyroid cancer in ultrasound parameters were positively correlated with the malignant degree of cancer (P<0.05); There was no significant difference between the accuracy of ultrasound in diagnosing thyroid cancer and the accuracy of postoperative pathological diagnosis (100.00%, P>0.05). The area under the curve was 0.828, specificity 91.25%, sensitivity 72.36%, negative predictive value 66.67%, and positive predictive value 81.94%; the area under the curve was 0.931, specificity was 96.42%, sensitivity 89.53%, negative predictive value 97.22%, and positive predictive value 79.19%. Conclusion Ultrasound has high sensitivity and specificity in the diagnosis of thyroid cancer, and can diagnose different forms of thyroid cancer through ultrasound images. Clinical diagnosis of thyroid cancer can be made by combining thyroid ultrasound diagnosis with relevant indicators.
