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...

we have developed a simple and precise paper chromatographic method for the determination of 4-hydroxy-3-methoxymandelic acid (vma) in urine. concentrations of vma in patients with neuroblastoma were increased in comparison to controls. the linearity was excellent in the concentration range tested. the within-assay coefficient of variation for control and patient urine was less than 2.2%. the r...

neuroblastoma, one of the common malignant childhood tumors, arises from neuroblast cells derived from theneural crest and destined for the adrenal medulla and the sympathetic nervous system and shows remarkable biologicalheterogeneity, resulting in favorable or unfavorable outcomes. some tumors make rapid progress with a fataloutcome. in other instances, the tumors regress spontaneously in inf...

background: neuroblastoma is the most common extra cranial malignant solid tumor of childhood. various molecular and cytogenetic factors have been implicated in the pathogenesis of neuroblastoma, some of which have proven useful in predicting clinical behavior. over expression of the oncogen n-myc, is an important indicator of prognosis. materials and methods: our study was performed from 2004 ...

The spontaneous regression of neuroblastoma to ganlioneuroma is a rare occurrence. Reviewing the literature, we found no more than 12casesreported.'•2.9.,o.'4.1s We report a case of metastatic neuroblastoma of multifocal skeletal and soft tissue areas with gross deformities which regressed to ganglioneuroma, with good prognosis.

background neuroblastoma is the most common extracranial malignant solid tumor in children under 5 years, and it is characterized by wide clinical and biological heterogeneity. n-myc oncogene amplification is considered to be one of the most important prognostic factors used to evaluate survival in these patients. objectives the aim of our study was to determine amplification of the n-myc oncog...

introduction: during the last 3 decades, human is exposed to extremely low frequency electromagnetic fields (elf-emf) emitted by power lines and electronic devices. it is now well accepted that elf-emf are able to produce a variety of biological effects, although the molecular mechanism is unclear and controversial. investigation of different intensities effects of 50 hz elf-emf on cell morphol...
