Identification of Sentinel Lymph Node in Stage I???II Breast Cancer With Lymphoscintigraphy and Surgical Gamma Probe: Comparison of Tc-99m MIBI and Tc-99m Sulfur Colloid

AIM: To evaluate the efficacy of the surgical gamma probe (SGP) after peritumoral injection of Tc-99m MIBI and filtered Tc-99m sulfur colloid (SC) in sentinel lymph node (SLN) detection in stage I and II breast cancer for deciding on the need for axillary dissection. MATERIALS AND METHODS: Thirty patients with stage I-II breast cancer had peritumoral injection of Tc-99m MIBI (74 MBq/0.2 mL [2 mCi/…
