IMPORTANCE Glioblastoma is the most devastating primary malignancy of the central nervous system in adults. Most patients die within 1 to 2 years of diagnosis. Tumor-treating fields (TTFields) are a locoregionally delivered antimitotic treatment that interferes with cell division and organelle assembly. OBJECTIVE To evaluate the efficacy and safety of(More)
The majority of tumors of the nervous system are sporadic. However, a subset of patients with tumors and their families are predisposed to developing cancers of the central nervous system and other organs because of a germline mutation. In the last decade, many of the genes responsible for these typically autosomal dominant familial tumor syndromes have(More)
BACKGROUND In this phase II trial, we investigated the efficacy of a metronomic temozolomide schedule in the treatment of recurrent malignant gliomas (MGs). METHODS Eligible patients received daily temozolomide (50 mg/m2) continuously until progression. The primary endpoint was progression-free survival rate at 6 months in the glioblastoma cohort (N =(More)
BACKGROUND High-dose methotrexate (MTX) and whole brain radiation therapy (WBRT) prolong survival in primary CNS lymphoma (PCNSL) patients but have been associated with delayed neurotoxicity. Consequently, patients are often treated with chemotherapy alone, and WBRT is deferred until relapse. METHODS We performed a retrospective study to evaluate the(More)
The objective of this study was to evaluate whether longitudinal levels of serum YKL-40 correlate with disease status or survival in adults with gliomas. Patients with histologically confirmed gliomas were eligible for this longitudinal study. Serum samples were collected prospectively and concurrently with MRI scans at multiple time points during the(More)
A subpopulation of familial cases of amyotrophic lateral sclerosis has been linked to mutations in the gene encoding Cu/Zn superoxide dismutase (SOD1). There is in vitro evidence that certain SOD1 mutants, in addition to their normal dismutation function, show increased ability of the enzyme to act as a peroxidase. This reaction is sensitive to inhibition(More)
Extended survival of 3 or more years is rare in patients with glioblastoma (GBM) but is becoming more common. Clinical outcome has not been well studied. We reviewed GBM patients at Memorial Sloan-Kettering Cancer Center between 2001 and 2003 who were seen for two or more visits. Patient characteristics and long-term clinical outcomes were reviewed for(More)
Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder with an incidence of about 1:2500 to 1:3000. It is caused by a germline inactivating mutation of the NF1 gene on chromosome 17. Patients with NF1 are at increased risk of developing a variety of tumors of the peripheral and central nervous system, including neurofibromas, plexiform(More)
BACKGROUND Patients with recurrent high-grade glioma (HGG) have a poor prognosis and there is no defined standard of care. High levels of vascular endothelial growth factor (VEGF) expressed in HGG make the anti-VEGF monoclonal antibody bevacizumab (BEV) of particular interest. PATIENTS AND METHODS In an ongoing registry data were collected from patients(More)
Despite moderate improvements in outcome of glioblastoma after first-line treatment with chemoradiation recent clinical trials failed to improve the prognosis of recurrent glioblastoma. In the absence of a standard of care we aimed to investigate institutional treatment strategies to identify similarities and differences in the pattern of care for recurrent(More)
