The Application Value of High-Frame-Frequency Contrast-Enhanced Ultrasound versus CT in Assessing the Status of Sentinel Lymph Nodes in Breast Cancer
Objective To explore the application of H-CEUS and CT in assessing the status of SLN in breast can-cer.Methods Fifty-four patients who underwent surgical treatment for unilateral breast cancer from March 2020 to May 2023 at our hospital were randomly selected.All study subjects underwent preoperative unilateral SLN scanning using H-CEUS with CT,and a total of 72 enlarged lymph nodes were detected,while the respective acoustic image characteristics describing the SLN were recorded.Based on the histopathological findings of post-operative SLN after surgical treatment,all study subjects were divided into lymph node non-metastatic group(n=22 cases)and metastatic group(n=50 cases).The sensitivity,specificity,positive predictive value,and negative predictive value of H-CEUS,CT,and the combined detection of the above two means were further analyzed.Results H-CEUS detected a total of metastatic lymph node cases and non-metastatic lymph node cases,while CT detected a total of metastatic lymph node cases and non-metastatic lymph node cases.Comparison with post-operative pathological results showed that the sensitivity,specificity and accuracy of H-CEUS were 86.00％,72.73％and 81.94％,respectively,while those of CT were 78.00％,63.64％and 73.61％,respectively.The sensi-tivity,specificity,and accuracy of H-CEUS combined with CT were 92.00％,86.36％,and 90.28％,respectively,which were higher than those of single H-CEUS and CT(P＜0.05).Conclusion H-CEUS and CT were able to assess the presence of early metastatic lesions in SLN of breast cancer,in which high-frequency ultrasonography had a greater predictive value of early metastasis in SLN of breast cancer(P＜0.05),and the combination of the two had the greatest predictive value(P＜0.05).
