Purpose:
To assess the value of preoperative axillary sonography possibly malignant for breast tumours.
Method:
We performed preoperative axillary sonography on 89 patients with suspicious breast tumours. In 78 cases, among which there were 74 invasive carcinomas, the surgery that followed included an axillary lymph node dissection and a comparison with the histology was possible.
Results:
The sonographic detection of axillary lymph node metastases has a sensitivity of 90% and a specificity of 91.7% in relation to all tumour stages and a sensitivity of 100% and specificity of 89.6% in relation to T1 tumours. In our analysis, therefore, it is vastly superior to a clinical examination of the axilla.
Conclusion:
Ultrasonography is an accurate imaging method for the diagnosis of axillary lymph node metastases. Broadening this analysis to include more patients will validate this conclusion. The results of our preliminary study suggest that this diagnostic method could help reduce unnecessary radical surgery in the treatment of breast cancer.
