Abstract

Aim of the study: The goal of this study was to evaluate the technical feasibility of sentinel node biopsy in breast cancer and its predictivity of axillary node status.

Patients and methods: Between January 1996 and June 1997, 128 patients with invasive breast carcinomas, referred to the Cancer Center of Strasbourg and Lyon (France), underwent lymphatic mapping (Patent Blue dye) and sentinel node biopsy followed by axillary clearance (Berg's level I to II).

Results: Sentinel node was identified in 76.5% of cases and was predictive of axillary status in 94.9% of cases. The false negative rate of the procedure was 5.1%. Sentinel lymph node was involved in 43.9% of cases and it was the only one involved in 30.2% of cases. The sensitivity of the procedure was 94% (CI: 95% = [88%-98%]) and its specificity 100%.

Conclusion: Actually considered as new attractive procedure under ongoing evaluation in prospective controlled trials, this study confirms the feasibility and reproductibility of lymphatic mapping and sentinel node biopsy, first stage before entering a new era of minimally invasive axillary surgery in breast cancer.
