AIMS: Pre-operative diagnosis of axillary nodal involvement in breast cancer allows one-stage axillary surgery. We evaluated the efficacy of axillary ultrasound (US) with US guided fine needle aspiration cytology (FNAC) in the diagnosis of axillary nodal involvement.
METHODS: Over a 13-month period, we performed US of 369 axillae in patients with screen-detected (n = 278) and symptomatic (n = 91) invasive carcinoma of the breast, at the same time as US of the primary tumour. If abnormal lymph nodes were demonstrated, a single US guided FNAC of the most abnormal node was performed. US and FNAC results were compared with the final histology of the surgically excised lymph nodes.
RESULTS: Among the 369 axillae studied, 102 had nodal macrometastases and 38 (37%) were identified by US guided FNAC. The rate was 33% in screen-detected and 44% in symptomatic patients. Sensitivity increased with increasing numbers of positive axillary nodes, and the more abnormal the appearances of the nodes on US.
CONCLUSION: US with FNAC of the most abnormal node allows pre-operative detection of a third of node positive axillae in screen-detected and over 40% of those with symptomatic breast cancer, allowing one-stage axillary surgery avoiding the sentinel node biopsy step in these patients.
