    Abstract:
    INTRODUCTION: In view of its predictive potential, axillary nodal status plays a particularly important role in breast cancer. The concept of sentinel node biopsy (SNB) revealed an accurate method with low postoperative morbidity for staging the axilla in patients with lymph node-negative breast cancer. The aim of this study was to show that SNB alone must have a place in routine clinical work and is reliable after preoperative chemotherapy (PC) and also in patients with multicentric tumors (MC). PATIENTS AND METHOD: Between April 1997 and March 2002, a total of 300 SNBs were performed in patients with uni- or bilateral breast cancer. Of them, 45 who had completed PC and 13 with multicentric lesions underwent SNB followed by axillary dissection. The sentinel nodes (SN) were labelled with a blue dye and radioactive colloids. Median follow-up was 33.6 months (range 8.2-67.0) (StAw 1.4). RESULTS: The detection rate in the learning phase was 81.8% and later 93.5%, independently of the size of the primary tumor. Overall accuracy and negative predictive value of the first 55 patients, after PC and in those with MC came to 97.8% and 96.7%, 97.6%, 95.8% and 100%, respectively. Through focused pathologic examination, staging was improved in 11.3% of patients. A year after the procedure, one patient developed recurrence. Morbidity after SNB alone was significantly lower than after axillary dissection. CONCLUSION: Our experience shows SNB to be reliable and accurate for axillary staging in breast cancer patients. Morbidity after SNB alone was low. Conclusive data on the local recurrence rate are not yet available. Under certain conditions, SNB appears to have future clinical potential, even in patients with PC and MC, which must be confirmed in further multicentric studies. In the meantime, this method has attained definite value in the surgical therapy of breast cancer patients.
