Sentinel Lymph Node Biopsy With Metastasis: Can Axillary Dissection Be Avoided in Some Patients With Breast Cancer?

Abstract

The primary tumor size and metastasis size in the SLN are independent factors in predicting the incidence of tumor in the non-SLNs. Therefore, the SLN biopsy alone may be adequate for staging and/or therapy decision making in patients with primary breast tumors < or = 2.0 cm and micrometastasis in the SLN.
