Intraoperative Injection of Radiocolloid for Sentinel Node Biopsy in Breast Cancer

Abstract

The sentinel lymph node identification rate of 94.6% for the intraoperative injection group was similar to other published sentinel lymph node identification rates (96%-100%). The positive sentinel lymph node rate was also comparable to that of published series. Intraoperative injection of radiocolloid for axillary sentinel node biopsy appears equivalent to preoperative injection and is a less painful experience for breast cancer patients.
