Radioguided localization of neuroblastomas in laparoscopic surgery using I-123- radiolabeled metaiodobenzylguanidine

摘要

Minimally invasive surgery has become widely recognized and is commonly used for the diagnosis and treatment of neuroblastoma. However, in post-chemotherapy status or during reoperations, it is occasionally difficult to precisely locate small neuroblastoma lesions, and this becomes prominent in endoscopic surgeries, in which tactile sense is essentially lost. Herein, we report our preliminary experience in two abdominal neuroblastoma cases undergoing laparoscopic tumor resection with aid of intraoperative I-123- metaiodobenzylguanidine (MIBG) radioguidance using a specifically designed gamma-probe. The procedure enables easier localization of viable neuroblastoma tissue, provided that the tumor shows moderate to high MIBG uptake. Pediatr Blood Cancer 2015;62:1297-1299.
