Dr.
Ley introduced sentinel lymph node biopsy for breast
cancer to Mississippi in 1998 and has performed over
two thousand such procedures. By participating in the
University of Louisville Breast Sentinel Node Registry,
Dr. Ley co-authored eight papers in peer-reviewed surgical
journals about the technique (complete bibliography
upon request). Using the injection of a radioisotope,
Technetium-99 sulphur colloid, with less radiation exposure
than a standard chest X-ray, the first lymph node draining
the breast, or the one that is theoretically at highest
risk for harboring microscopic metastatic disease, is
identified through a small incision using the Neoprobe
(TM) gamma counter device. This allows removal of only
the nodes at risk for disease, and avoids a complete
lymph node dissection in patients with negative sentinel
nodes. The risk of lymphedema and nerve injury after
a sentinel node biopsy is much lower, and the accuracy
of the technique has been validated in literally hundreds
of published reports. Many patients undergoing breast
conserving surgery are able to undergo sentinel node
biopsy via a transmammary technique and avoid a second
incision in the axilla. |
