Abstract
AimTo show our experience using the portable gamma camera during surgery in the detection of the sentinel node in breast cancer. Material and methodsA total of 46 women diagnosed with breast cancer were included. This study was carried out by means of the periareolar intradermal injection. Planar images and SPECT/CT were acquired. On the following day, the sentinel nodes were localized intraoperatively with a portable gamma camera and a gamma probe. Images of the axilla in anterior and lateral projections were acquired before and after extraction of all the sentinel nodes. ResultsThe images acquired with the portable gamma-camera during the operation showed no activity in all the patients after the removal of the sentinel nodes. In four out of the 46 cases, the portable gamma camera provided relevant information during the procedure (it detected a sentinel node in two cases in which it had not been detected prior to the surgery and it oriented the surgeon in the localization of low activity nodes when the probe screening had been negative). ConclusionsThe intraoperative portable gamma camera to detect the sentinel node in breast cancer patients is useful in order to ensure, independent of the surgeon that all the sentinel nodes have been removed. It can also help guide the surgeon in the event of a single low activity sentinel node.
