Sentinel lymph node biopsy in early XXXX : the first 100 cases performed in a teaching institute.

@entity1 @entity0 @entity4298
BACKGROUND: The histologic status of axillary lymph nodes is one of the most important prognostic factors in @entity0 and influences the management of these @entity1 . Axillary lymph node dissection was traditionally performed in all @entity1 to obtain this information but this procedure carries a considerable rate of complications. Recently, sentinel lymph node biopsy has emerged as an accurate and minimally invasive tool for predicting the axillary nodal status and has become the standard of care in selected @entity1 with @entity0 . OBJECTIVE: To examine the accuracy of @entity4298 biopsies performed by surgical residents during surgical resident training. METHODS: This prospective, randomized controlled study included 100 consecutive @entity1 with clinically early @entity0 (T1-T2, N0, M0). Lymphatic mapping was performed using radiotracers, blue dye, or both. Formal axillary lymph node dissection completed the operations in all @entity1 . All operations were performed by surgical residents under the supervision of senior surgeons. RESULTS: The overall rate of identification of sentinel lymph nodes was 92%. The accuracy of @entity4298 biopsy in reflecting the axillary nodal status was 96% with a false negative rate of 5.7%. CONCLUSIONS: Sentinel lymph node biopsy is an accurate method for the evaluation and staging of regional lymph nodes in @entity0 @entity1 . A dedicated instruction program for surgical residents may increase the standard of care and lead to highly trained surgeons in the management of early @entity0 .
