Role of sentinel lymph node biopsy in early breast cancer.
Current literature has suggested that sentinel lymph node biopsy may replace axillary dissection as the nodal staging procedure of choice in early breast cancer. The aim of this study is to evaluate the effectiveness and accuracy of sentinel lymph node biopsy using methylene blue dye in predicting axillary nodal status in early breast cancer with clinically impalpable axillary lymph nodes. In the period between June 2005 and May 2009, 50 patients with early breast cancer and clinically impalpable axillary lymph nodes, underwent sentinel lymph node biopsy using methylene blue dye followed by completion of axillary dissection in the same setting after taking a written consent from the patients. Of the included 50 patients, sentinel lymph node biopsy was successful in 48 patients (96.0%). Accuracy of sentinel lymph node biopsy was 95.8%, sensitivity was 90.0%, false negative rate was 6.7%, negative predictive value was 93.3%.
