Summary

It has been hypothesized that the proximity of the anatomic locations of the arm lymphatic drainage system to the breast lymphatic system in the axilla put the arm lymphatics at risk for disruption during a sentinel lymph node biopsy (SLNB) and/or axillary lymph node dissection (ALND). Therefore, mapping the drainage of the arm in addition to the drainage of the breast during the procedure would potentially decrease the incidence of arm lymphatic disruption and subsequent development of lymphedema while providing adequate axillary breast nodes needed for staging.

Interventions

PROCEDURE

Injection of isotope

On the day of surgery, if the radioactive SLN cannot be located using the gamma probe prior to incision, lymphazurin or methylene blue dye will be used in the breast in the subareolar plexus at the discretion of the surgeon for assistance in identifying the sentinel nodes. This contingency, expected to occur \<3% of the time, will be used since locating the SLN for staging is of greater importance than the study. If radioactive isotope is sufficient to identify the sentinel node draining from the breast, then the blue dye will be injected dermally in the upper inner arm along the bicipital groove of the ipsilateral arm in order to locate the draining lymphatics from the arm. No more than 5cc of blue dye will be injected in any of the above mentioned scenarios.

PROCEDURE

Axillary lymph node dissection

The one-year lymphedema rate among subjects undergoing axillary lymph node dissection with or without sentinel lymph node biopsy is ≥ 0.13. With our sample size of 58 subjects undergoing ALND, we will reject that hypothesis in favor of the alternative-that the lymphedema rate is \<0.13 for subjects undergoing ALND-if lymphedema is confirmed in three or fewer (ie, 0, 1, 2, or 3) subjects.
