The Role of Lymphoscintigraphy in the Management of the Patient With Breast Cancer

Introduction: Regional nodal status is the most powerful predictor of recurrence and survival in women with breast cancer. Lymphatic mapping and sentinel lymph node (SLN) biopsy have been found to accurately predict the regional nodal status. Preoperative lymphoscintigraphy has been used in melanoma patients to identify the basins at risk for metastases when primary sites are located in watershed areas of the body. This study was performed to define the role of lymphoscintigraphy for axillary nodal staging in women with breast cancer. Specifically, can preoperative lymphoscintigraphy define a population of women with breast cancer who have multidirectional drainage or who do not drain to the axilla and need no axillary dissection?
