  Purpose

The advent of mammography and increased awareness of breast cancer has resulted in detection of smaller tumors, the majority of which would not have had metastasized to the axillary lymph nodes. The sentinel node (SN) is presumably the first echelon node in the axillary basin to become involved with metastatic breast cancer cells. Sentinel node biopsy (SNB) in operable breast cancer has gained popularity since it promises to avoid treatment of the axilla when the nodes are negative for metastasis. Advances in technology (radio-guided SNB) is associated with a risk of false negative SN reporting in 4-12%. The consequence of leaving behind untreated positive non-sentinel nodes in the axilla is a potential risk for axillary recurrence. Axillary sampling is a simple and inexpensive procedure in which level I nodes are removed by a blind dissection. The investigators critically analyzed the efficacy of both the procedures separately in consecutive pilot studies i.e., targeted SNB versus blind axillary sampling. The current study is planned as a prospective comparison study where a patient undergoes both the procedures in the same surgical intervention and thus provides an immediate comparison of the two techniques with respect to their effectiveness.
