The efficacy of Tc-99m sestamibi for sentinel node mapping in breast carcinomas: comparison with Tc-99m antimony sulphide colloid
open access
Abstract
MATERIAL AND METHODS: Fifty patients with early-stage breast cancer were included in our study. 17.5 MBq Tc-99m-MIBI was injected intradermally to 25 patients and the remainders were injected with the same dose of Tc-99m-antimony sulphide colloid. Anterior and lateral static images were taken at 2 minutes. If sentinel lymph node was not detected, delayed imaging by up to 180 minutes was carried out. The patients were operated on 2–4 hours post-injection. Sentinel lymph node biopsy was performed by the aid of gamma probe and blue dye during surgery.
RESULTS: In the Tc-99m-MIBI group, 23 patients had lymph nodes on scintigraphy images, and sentinel nodes were detected during surgery in all 23 patients. In the Tc-99m-antimony sulphide colloid group, 24 patients had lymph nodes on scintigraphy images, and sentinel nodes were identified during surgery in 24 patients.
CONCLUSIONS: We concluded that 99mTc-MIBI is a suitable radiopharmaceutical for sentinel node detection.
