Abstract

The feasibility, accuracy and clinical significance of sentinel lymph node biopsy for patients with breast cancer after neoadjuvant chemotherapy has not yet been determined. The aim of this study was to investigate these questions. Dual agent-guided sentinel lymph node biopsy with preoperative lymphoscintigraphy was performed on 17 breast cancer patients after neoadjuvant chemotherapy at the Department of General and Thoracic Surgery, National Institute of Oncology, Budapest, from April 2004 to August 2005. Patients with clinically lymph node-negative breast cancer less than 3 cm in size after neoadjuvant chemotherapy were enrolled in the study. Lymphoscintigraphy showed no axillary lymphatic drainage in 7 patients (41%), and no sentinel lymph node could be identified during surgery in these patients. Axillary lymph nodes were histologically positive in 6 (86%) out of these 7 patients. Sentinel lymph node biopsy was successful in 10 patients (59%), and in 8 (80%) of them the sentinel lymph node proved to be positive pathologically. False negative sentinel lymph node biopsy did not occur. Axillary lymph node status was histologically positive in 14 (82%) out of the 17 patients. The predictable value of the clinical examination o...Continue Reading
