Study Stopped
After initiation of study many studies reported an equivalence of SNB and ALND which led to widespread adoption of the former as standard procedure.

Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Comparison of methodologies in predicting status of axillary lymph nodes
The patient enrolled on this study will be planned for surgery and outcome will be measured after avability of histo-pathological report.
Within 30 days after surgery
Secondary Outcomes (4)
Number of lymph nodes identified by sentinel node biopsy and axillary sampling
Within 30 days of surgery
Number of times the sentinel node is found within the sampled nodes
Within 30 days of surgery
False negative rate by each method
within 30 days of surgery
Negative predictive value for each method
within 30 days of surgery
Study Arms (1)
Radio guided Sentinle node biopsy
EXPERIMENTALThe radiolabeled Tc-99 colloid or phytate (500 Mbq) will be injected into the primary tumor 2 hours before surgery. A localized scintiscan will then be performed to confirm the radiolabeling of the sentinel node before surgery and for documentation. Isosulphan blue dye will be injected subdermal (0.5ml) over the tumor and intraparenchymal (3-4ml) towards the axilla 10-15mins before incision.
