AbstractThe purpose of this study was to evaluate the feasibility of sentinel lymph node mapping in patients undergoing neoadjuvant chemotherapy for breast carcinoma prior to lumpectomy or mastectomy and sentinel lymph node mapping followed by complete axillary dissection. A retrospective analysis of 14 patients from February 1998 to July 2000 with stage I to stage IIIB breast cancer diagnosed by core biopsy underwent neoadjuvant chemotherapy (doxorubicin/cyclophosphamide) prior to definitive surgery, including lumpectomy or mastectomy and sentinel lymph node mapping, followed by full axillary dissection. Thirteen of 14 patients had successful sentinel lymph node identification (93%), and all 14 underwent full axillary dissection. An average of 2.2 sentinel nodes and a median of 16 axillary lymph nodes (including sentinel nodes) were found per patient. Of the 13 patients in whom a sentinel lymph node was identified, 10 were positive for metastases (77%). Only 4 of the 10 had further axillary metastases (40%). Three patients had negative sentinel lymph nodes shown by hematoxylin and eosin and cytokeratin stainings and had no axillary metastases (0% false negative). The single patient in whom a sentinel lymph node could not be identified had stage IIIA disease with extensive lymphatic tumor emboli. Sentinel lymph node mapping is feasible in neoadjuvant chemotherapy breast cancer patients and can spare a significant number of patients the morbidity of full axillary dissection. Further study to evaluate sentinel lymph node mapping in this patient population is warranted.
