Intra-operative examination of the sentinel node in breast cancer. (2008)

Abstract Intra-operative sentinel node analysis allows immediate progression to axillary clearance in patients with node positive breast cancer and reduces the need for re-operation. Despite this, intra-operative sentinel node analysis is infrequently performed in Ireland. We report our experience using this technique. Sentinel node biopsy was performed in 47 consecutive patients with symptomatic T1-T2 clinically node negative breast cancer. Sentinel nodes were examined intra-operatively by frozen section and imprint cytology and definitive histological assessment was performed on paraffin-embedded tissue. The sentinel node was identified in 46 (98%) patients. Twelve patients had axillary metastases. The sensitivity of intra-operative analysis in identifying nodal metastases was 92%. False negative rate was 8%, negative predictive value 97%, and specificity 100%. Intra-operative analysis of the sentinel node allowed re-operation to be avoided in 92% of patients with axillary node metastases. In our experience this technique can be readily introduced with reliable outcomes.
