Abstract:
Objective:To analyze the application of Cho peak value and color doppler ultrasound blood flow score in the early diagnosis of breast cancer, and to evaluate the relationship between Cho peak value, blood flow score, TNM stage and prognosis quality.Methods:A total of 82 patients with breast cyst admitted from Jan. 2015 and Dec. 2019 were selected as subjects for the study. ROC curve was used to compare the ability of color doppler flow score and functional magnetic resonance imaging (fmri) in the diagnosis of breast cancer when used alone or in combination. Logistic regression model was used to analyze the factors affecting the prognosis quality and TNM staging of patients.Results:The breast cancer group’s Cho value and blood flow signal score were significantly higher than the benign breast lesion group, and the difference was statistically significant (Cho value: t=43.977, P<0.001; blood flow signal score: t=22.071, P<0.001) ; The sensitivity, specificity and AUC of MRS combined with Doppler ultrasound for differential diagnosis of breast cancer are significantly higher than MRS or Doppler ultrasound alone, and the difference was statistically significant (sensitivity: χ2=4.514, P=0.016; specificity: χ2=4.858, P=0.013; AUC: Z=5.251, P<0.001) ; Cho value of patients with good prognosis group ( t=3.984, P<0.001) and blood flow signal score ( t=4.213, P<0.001) were significantly lower than those in the poor prognosis group; Cho value ( t=3.612, P<0.001) and blood flow signal score ( t=3.835, P<0.001) of TNM stage 0-Ⅱ patients were significantly lower than those of stage Ⅲ-Ⅳ group, the difference was statistically significant; the Cho value of the MRS scan and the patient’s prognosis quality ( OR=1.837, 95% CI=1.210-2.788, P=0.004) and TNM stage ( OR=1.818, 95% CI=1.224~2.702, P=0.003) was significantly positively correlated. The blood flow signal and the patient’s prognostic quality ( OR=1.906, 95% CI=1.105~3.287, P=0.020) and TNM stages ( OR=1.799, 95% CI=1.232-2.626, P=0.002) also showed a significantly positive correlation. Conclusion:The combination of Cho peak value and color doppler ultrasound blood flow score can significantly improve the early diagnosis efficiency of breast cancer, and Cho peak value and blood flow score are independent factors affecting TNM staging and prognosis.
