- Abstract: Objective To analyze the diagnostic value of ultrasound blood quantitative parameters combined with murine sarcoma filtering toxin oncogenic homolog B(BRAF)gene mutation in Hashimoto's thyroiditis(HT)with thyroid carcinoma.Methods A total of 86 patients with HT and thyroid nodules in Sir Run Run Hospital,Nanjing Medical University from June 2020 to June 2022 were selected as the research objects.The patients with thyroid cancer were included into the malignant group(n=26),and the patients with benign thyroid nodules were included into the benign group(n=60)according to the pathological examination results.The patients in the malignant group was divided into the metastasis group(n=10)and the non-metastasis group(n=16)according to whether lymph node metastasis occurred.All subjects underwent color Doppler ultrasonography and BRAF gene mutation detection.The pulsatility index(PI),resistance index(RI),peak systolic velocity(S),end diastolic velocity(D),peak systolic velocity to end diastolic velocity ratio(S/D)and BRAF gene mutation between the malignant group and the benign group were compared.The detection rate of blood flow signals by CDFI,the detection rate of blood flow signals of grade 2 to 3 and the mutation of BRAF gene between the metastasis group and the non-metastasis group were compared.The value of the above blood parameters and BRAF gene mutations in the diagnosis of HT complicated with thyroid cancer was evaluated by receiver operating characteristic(ROC)curve,and the value of the above blood parameters and BRAF gene mutation in the diagnosis of lymph node metastasis of thyroid cancer was evaluated.Results The PI,RI,S,D,S/D and positive rate of BRAF gene mutation in the malignant group were significantly higher than those in the benign group(P<0.05).The detection rate of blood flow signals by CDFI,the detection rate of blood flow signals of grade 2 to 3,and the positive rate of BRAF gene mutation in the metastasis group were significantly higher than those in the non-metastasis group(P<0.05).ROC curve analysis showed that the area under the curve(AUC)of RI,PI,S,D,S/D and BRAF gene mutation in the combined assessment of HT complicated with thyroid cancer was 0.951,with the sensitivity of 88.46%and the specificity of 93.33%,and the efficiency of combined assessment was better than that of the independent assessment of each index.Meanwhile,the AUC of the detection rate of blood flow signals by CDFI,the detection rate of blood flow signals of grade 2 to 3,and BRAF gene mutation in the combined assessment of lymph node metastasis of thyroid cancer was 0.938,and the efficiency of combined assessment was better than that of the independent assessment of each index.Conclusion The ultrasound blood quantitative parameters combined with BRAF gene mutation has certain value in the evaluation of HT with thyroid cancer and lymph node metastasis,and the combined evaluation of each index is more effective.
