Diagnostic efficacy of SPECT/CT,conventional ultrasound and mammography for axillary lymph node metastasis in breast cancer

Objective:To evaluate the diagnostic efficacy of SPECT/CT imaging,conventional ultrasound and mammography in the diagnosis of axillary lymph node metastasis in breast cancer.Methods:The sensitivity,specificity,accuracy and consistency of various diagnostic methods were evaluated by retrospective analysis of 99Tcm-SPECT/CT imaging,conventional ultrasound and Molybdenum target imaging in 42 breast cancer patients admitted from March 2013 to November 2016.Results:The sensitivity and accuracy (88.5%,81.0%) of axillary lymph nodes in diagnosis of breast cancer were significantly better than those of conventional ultrasound (50.0%,59.5%) and Molybdenum target (26.9%,45.2%).There was no significant difference in the specificity of the three methods.The consistent analysis of SPECT/CT results and pathological results (Kappa=0.59) was superior to conventional ultrasound (Kappa=0.25) and Molybdenum target imaging (Kappa=0.13).SPECT/CT imaging found that the positive rate of axillary lymph node metastasis was 66.7%,which was significantly higher than that of Molybdenum target imaging (26.2%) and conventional ultrasound imaging (40.5%),both of which were statistically significant (P＜0.05).The ROC curve analysis of SPECT/CT target and background radiation count ratio was 3.55,and the corresponding sensitivity,specificity,and accuracy were 81%,94% and 86%.Conclusion:SPECT/CT imaging has good diagnostic value in preoperative diagnosis of axillary lymph node metastasis of breast cancer and is consistent with pathological diagnosis.
