Improved outcome of (131)I-mIBG treatment through combination with external beam radiotherapy in the SK-N-SH mouse model of neuroblastoma.

CONCLUSIONS: This study demonstrates that combining EBRT and MRT has an enhanced therapeutic effect and emphasizes the importance of treatment scheduling according to pathophysiological criteria such as tumour vessel permeability and tumour growth kinetics.

In this study, we investigated the effects of ECH and ASB on long-term memory in mice using a battery of behavioral tests. Acute ECH treatments dose-dependently facilitated nonspatial, but not spatial, memory. ECH treatments also upregulated expression of tyrosine hydroxylase, the enzyme mediating catecholamine synthesis, in neuroblastoma cell culture. Acute ASB treatments similarly improved nonspatial memory, whereas chronic ASB treatments improved both nonspatial and spatial memory. In accordance with such behavioral effects, the increased ratio of tissue concentrations of dopamine metabolites over dopamine in striatal r...

Malignant gastrointestinal neuroectodermal tumour is an extremely rare neoplasm that arises in the wall of the small bowel, stomach or large bowel in young-aged and middle-aged adults. Histologically, it is generally characterized by monomorphic cells with clear cytoplasma, S-100 protein expression, and EWSR1 gene translocation. To the best of our knowledge, we describe for the first time, the case of a young woman with a diagnosis of metastatic gastrointestinal neuroectodermal tumour arising from ileum, who had a childhood adrenal neuroblastoma with liver, bone and lymph nodes metastasis, treated with four cycles of chemo...

ia Lepore Previous works showed that spatially resolved Raman spectra of cytoplasm and nucleus region of single cells exposed to X-rays evidence different features. The present work aims to introduce a new approach to profit from these differences to deeper investigate X-ray irradiation effects on single SH-SY5Y human neuroblastoma cells. For this aim, Raman micro-spectroscopy was performed in vitro on single cells after irradiation by graded X-ray doses (2, 4, 6, 8 Gy). Spectra from nucleus and cytoplasm regions were selectively acquired. The examination by interval Principal Component Analysis (i-PCA) of the differen...

Abstract PURPOSE: The 2-part, phase 1/2a, open-label study (NCT01677741) sought to determine the safety, tolerability, pharmacokinetics, and preliminary activity of dabrafenib in pediatric patients with advanced BRAF V600-mutated cancers. EXPERIMENTAL DESIGN: This phase 1 dose-finding part treated patients aged 1 to 52 weeks and 52% undergoing treatment at data cutoff date. The most common grade 3/4 adverse events suspected to be related to study drug were maculopapular rash and arthralgia (2 patients each). No dose-limiting toxicities were observed. Pharmacokinetic analyses showed a dose-dependent increase i...

AbstractPurpose of ReviewWe aim to review the most recent findings in the use of NK cells in childhood cancers.Recent FindingsNatural killer cells are cytotoxic to tumor cells. In pediatric leukemias, adoptive transfer of NK cells can bridge children not in remission to transplant. Interleukins (IL2, IL15) can enhance NK cell function. NK cell-CAR therapy has advantages of shorter life span that lessens chronic toxicities, lower risk of graft versus host disease when using allogeneic cells, ability of NK cells to recognize tumor cells that have downregulated MHC to escape T cells, and possibly less likelihood of cytokine s...

ConclusionAdrenal neuroblastoma in elderly adults is a very rare disease with sparse data available in the literature. Early stage disease could be managed by surgical resection alone. However, the prognosis is significantly worse than that observed in pediatric patients. Further research focusing on tumor biology and therapy for this rare malignancy in adults may help to improve disease outcome.
