Difluoromethylornithine (DFMO) will be used in an open label, single agent, multicenter, study for patients with neuroblastoma in remission. In this study subjects will receive 730 Days of oral difluoromethylornithine (DFMO) at a dose of 500 to 1000 mg/m2 BID on each day of study. This study will focus on the use of DFMO in high risk neuroblastoma patients that are in remission as a strategy to prevent recurrence.

A prospective open label, multicenter study to evaluate the feasibility and acute toxicity of using molecularly guided therapy in combination with standard therapy followed by maintenance ...
The purpose of this research study is to evaluate a new investigational drug to treat neuroblastoma. This study drug is called DFMO. The objectives of this study will be to monitor for s...
To provide DFMO in an expanded use setting to subjects with relapsed rare tumors with increased LIN28 expression or MYCN amplification or up regulation of ornithine decarboxylase.
This study is a multicenter, double-blind, placebo-controlled, 2:1 randomly assigned, phase 1 clinical trial for individuals with type 1 diabetes. It is a blinded dose-ranging study enroll...
A clinical study of the efficacy of oral alpha-difluoromethylornithine (eflornithine or DFMO) in male and female subjects ages 30-60 with gastric premalignant lesions in two high risk regi...
Altered levels of polyamines in biological specimens have been suggested as potential biomarkers for cancer. Difluoromethylornithine (DFMO, an irreversible inhibitor of ornithine decarboxylase) is rep...
Neuroblastoma is a lethal tumor that commonly occurs in children. Polymorphisms in reportedly influence risk for several types of cancer, though their roles in neuroblastoma remain unclear. Here we e...
Two new neuroblastoma susceptibility loci at 3q25 (RSRC1 rs6441201 G > A) and 4p16 (CPZ rs3796725 T > C and rs3796727 A > G) were identified by a genome-wide association study (GWAS) invol...
Neuroblastoma is characterized by substantial clinical heterogeneity. Despite intensive treatment, the survival rates of high-risk neuroblastoma patients are still disappointingly low. Somatic chromos...
Neuroblastoma is the most common diagnosed tumor in infants and the second most common extracranial tumor of childhood. The survival rate of patients with high-risk neuroblastoma is still very low des...
An indolocarbazole that is a potent PROTEIN KINASE C inhibitor which enhances cAMP-mediated responses in human neuroblastoma cells. (Biochem Biophys Res Commun 1995;214(3):1114-20)
A malignant olfactory neuroblastoma arising from the olfactory epithelium of the superior nasal cavity and cribriform plate. It is uncommon (3% of nasal tumors) and rarely is associated with the production of excess hormones (e.g., SIADH, Cushing Syndrome). It has a high propensity for multiple local recurrences and bony metastases. (From Holland et al., Cancer Medicine, 3rd ed, p1245; J Laryngol Otol 1998 Jul;112(7):628-33)
A moderately malignant neoplasm composed of primitive neuroectodermal cells dispersed in myxomatous or fibrous stroma intermixed with mature ganglion cells. It may undergo transformation into a neuroblastoma. It arises from the sympathetic trunk or less frequently from the adrenal medulla, cerebral cortex, and other locations. Cervical ganglioneuroblastomas may be associated with HORNER SYNDROME and the tumor may occasionally secrete vasoactive intestinal peptide, resulting in chronic diarrhea.
Genes of IAP elements (a family of retrovirus-like genetic elements) which code for virus-like particles (IAPs) found regularly in rodent early embryos. ("Intracisternal" refers to the cisternae of the endoplasmic reticulum.) Under certain circumstances, such as DNA hypomethylation they are transcribed. Their transcripts are found in a variety of neoplasms, including plasmacytomas, neuroblastoma, rhabdomyosarcomas, teratocarcinomas, and colon carcinomas.
Family of retrovirus-associated DNA sequences (ras) originally isolated from Harvey (H-ras, Ha-ras, rasH) and Kirsten (K-ras, Ki-ras, rasK) murine sarcoma viruses. Ras genes are widely conserved among animal species and sequences corresponding to both H-ras and K-ras genes have been detected in human, avian, murine, and non-vertebrate genomes. The closely related N-ras gene has been detected in human neuroblastoma and sarcoma cell lines. All genes of the family have a similar exon-intron structure and each encodes a p21 protein.
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
