BACKGROUND Neuroblastoma is a childhood malignancy of sympathetic embryonal origin. A high potential for differentiation is a hallmark of neuroblastoma cells. We have previously presented data to suggest that in situ differentiation in tumors frequently proceeds along the chromaffin lineage and that

Pituitary adenylate cyclase-activating polypeptide (PACAP) and vasoactive intestinal peptide (VIP) are two related peptides acting as neurotransmitters/neuromodulators in central and peripheral nervous system. They are also involved in cancer showing a controversial role. Particulary, they are

BACKGROUND The usefulness of 2-[(18)F]-fluoro-2-deoxy-D-glucose ((18)F-FDG) positron emission tomography (PET) has been investigated in thymic epithelial tumors. However, little is known about PET imaging of (18)F-FDG in primary non-thymic mediastinal neoplasms. The aim of this study is to explore

Peripheral neuroblastic tumors (PNT), including neuroblastomas, pheochromocytomas, ganglioneuromas, and paragangliomas, have been reported in association with congenital heart disease (CHD). If a significant correlation between PNT and CHD could be demonstrated, it would suggest that peripheral

Neuroblastoma (NB) is the most common extracranial solid tumor of childhood. The clinical course may range from spontaneous regression towards ganglioneuroblastoma/ganglioneuroma or maturation to a very aggressive form characterized by an extensive hypoxic area. In solid tumors, extracellular

GLUT1 is a hypoxia-induced gene that has many biologically important functions, and the overexpression of the GLUT1 protein correlates with poor prognosis in several adult cancers. The clinical significance of the GLUT1 protein in peripheral neuroblastic tumours (NTs) has not been comprehensively

Congenital central hypoventilation syndrome (CCHS or Ondine's curse; OMIM 209880) is a life-threatening disorder involving an impaired ventilatory response to hypercarbia and hypoxemia. This core phenotype is associated with lower-penetrance anomalies of the autonomic nervous system (ANS) including

The overexpression of carbonic anhydrase IX, a hypoxia-induced enzyme, is associated with an adverse prognosis in many cancers. However, carbonic anhydrase IX expression in neuroblastoma, the most common extracranial pediatric tumor, has not been reported. Membranous and/or strong cytoplasmic
