Objetivo: Avaliar se a radioiodoterapia com 131I-metaiodobenzilguanidina (131I-mIBG) aumenta sobrevida de pacientes diagnóstico neuroblastoma, mIBG-ávido, refratários ao tratamento ou alto risco para recidiva, independentemente do estadiamento da doença. Métodos: Revisão sistemática literatura. Consultadas as bases Medline (PUBMED), EMBASE e Cochrane Library, sendo incluídos estudos disponíveis...

Radio-iodinated m-iodobenzylguanidine (MIBG), an analogue of the neurotransmitter norepinephrine (NE), is increasingly used in the diagnosis and treatment of neural crest tumors. Active uptake and subsequent retention of MIBG and NE was studied in human neuroblastoma SK-N-SH cells. Neuron-specific uptake of [125I]MIBG and [3H]NE saturated at extracellular concentration of 10(-6) M and exceeded ...

Recently, reliable and clear evidence for the usefulness of 123I-MIBG scintigraphy in the diagnosis of Parkinson's disease (PD) has been accumulated and it has become increasingly popular as one of the most accurate means of diagnosing the disease. PD, one of the most common neurodegenerative disorders, is characterized by resting tremor, rigidity, bradykinesia or akinesia, and postural instabi...

Introduction: The present study was aimed to assess the diagnostic performance of the two imaging methods of 131I-metaiodobenzylguanidine (131I-MIBG) and 99mTc-hydrazinonicotinyl-Tyr3-Octreotide (99mTc-HYNIC-TOC) in diagnosis and localization of pheochromocytoma and neuroblastoma. Methods: This study ...

Neuroblastoma is the third most common malignancy of childhood. Nowadays, MIBG has become a central procedure for staging and defining extent and location of neuroblastoma tumors. The recommendations of the International Neuroblastoma Staging System (INSS) indicate that MIBG scintigraphy must be performed in patients with neuroblastoma at the time of initial staging and as a followup tool durin...

(I-MIBG) Imaging in Brugada Syndrome To the Editor: We read with interest a recent article in Circulation by Wichter et al1 on cardiac autonomic dysfunction in Brugada syndrome. The authors demonstrated that regionally reduced iodine-123-metaiodobenzylguanidine (I-MIBG) uptake in the inferior and septal left ventricular wall was present in 8 (47%) of 17 patients with Brugada syndrome but in non...

Radio-labelled MIBG therapy has been tried in the treatment of advanced stage III and IV neuroblastoma in an attempt to improve patients outcome. The use of radiolabelled MIBG to treat neuroblastoma has arisen from the high sensitivity and specificity of in vivo MIBG imaging for detection of primary and metastatic tumours. Although, clinical trials have been performed to determine the role of M...

PURPOSE Children with relapsed neuroblastoma have poor survival. It is crucial to have a reliable method for evaluating functional response to new therapies. In this study, we compared two functional imaging modalities for neuroblastoma: metaiodobenzylguanidine (MIBG) scan for uptake by the norepinephrine transporter and [(18)F]fluorodeoxyglucose positron emission tomography (FDG-PET) uptake fo...

Purpose: I-metaiodobenzylguanidine (MIBG) is a radiopharmaceutical with activity in neuroblastoma. Vorinostat is a histone deacetylase inhibitor that has radiosensitizing properties. The goal of this phase I study was to determine the MTDs of vorinostat and MIBG in combination. Experimental Design: Patients 30 years with relapsed/refractory MIBG-avid neuroblastoma were eligible. Patients receiv...
