Intradural spinal tumors in adults-update on management and outcome.

Among spinal tumors that occur intradurally, meningiomas, nerve sheath tumors, ependymomas, and astrocytomas are the most common. While a spinal MRI is the state of the art to diagnose intradural spinal tumors, in some cases CT scans, angiography, CSF analyses, and neurophysiological examination can be valuable. The management of these lesions depends not only on the histopathological diagnosis but also on the clinical presentation and the anatomical location, allowing either radical resection as with most extramedullary lesions or less invasive strategies as with intramedullary lesions.

Superselective intraarterial cerebral infusion of cetuximab after osmotic blood/brain barrier disruption for recurrent malignant glioma: phase I study.

Objective To establish a maximum tolerated dose of superselective intraarterial cerebral infusion (SIACI) of Cetuximab after osmotic disruption of the blood-brain barrier (BBB) with mannitol, and examine safety of the procedure in patients with recurrent malignant glioma. Methods A total of 15 patients with recurrent malignant glioma were included in the current study. The starting dose of Cetuximab was 100 mg/m(2) and dose escalation was done to 250 mg/m(2).

Neuro-oncology biotech industry progress report.

The Brain Tumor Biotech Center at the Feinstein Institute for Medical Research, in collaboration with Voices Against Brain Cancer hosted The Brain Tumor Biotech Summit at in New York City in June 2015. The focus was once again on fostering collaboration between neuro-oncologist, neurosurgeons, scientists, leaders from biotechnology and pharmaceutical industries, and members of the financial community. The summit highlighted the recent advances in the treatment of brain tumor, and specifically focused on targeting of stem cells and EGFR, use of prophage and immunostimulatory vaccines, retroviral vectors for drug delivery, biologic prodrug, Cesium brachytherapy, and use of electric field to disrupt tumor cell proliferation.

Vincent du Vigneaud: following the sulfur trail to the discovery of the hormones of the posterior pituitary gland at Cornell Medical College.

In 1955, Vincent du Vigneaud (1901-1978), the chairman of the Department of Biochemistry at Cornell University Medical College, was awarded the Nobel Prize for Chemistry for his research on insulin and for the first synthesis of the posterior pituitary hormones-oxytocin and vasopressin. His tremendous contribution to organic chemistry, which began as an interest in sulfur-containing compounds, paved the way for a better understanding of the pituitary gland and for the development of diagnostic and therapeutic tools for diseases of the pituitary. His seminal research continues to impact neurologists, endocrinologists, and neurosurgeons, and enables them to treat patients who had no alternatives prior to du Vigneaud's breakthroughs in peptide structure and synthesis.

Multifunctionalization of cetuximab with bioorthogonal chemistries and parallel EGFR profiling of cell-lines using imaging, FACS and immunoprecipitation approaches.

The ability to derivatize antibodies is currently limited by the chemical structure of antibodies as polypeptides. Modern methods of bioorthogonal and biocompatible chemical modifications could make antibody functionalization more predictable and easier, without compromising the functions of the antibody. To explore this concept, we modified the well-known anti-epidermal growth factor receptor (EGFR) drug, cetuximab (Erbitux®), with 5-azido-2-nitro-benzoyl (ANB) modifications by optimization of an acylation protocol.

Conservative management of cavernous sinus cavernous hemangioma in pregnancy.

Cavernous sinus cavernous hemangiomas in pregnancy are extremely rare lesions. The precise management of these lesions remains unknown. The authors present a case of a cavernous hemangioma in pregnancy, centered within the cavernous sinus that underwent postpartum involution without surgical intervention.

Expanding the borders: the evolution of neurosurgical approaches.

In this article the authors discuss the development of neurosurgical approaches and the advances in science and technology that influenced this development throughout history. They provide a broad overview of this interesting topic from the first attempts of trephination by ancient cultures to the work of the pioneers of neurosurgery and the introduction of microsurgery.

Results and risk factors for recurrence following endoscopic endonasal transsphenoidal surgery for pituitary adenoma.

Background: Endoscopic endonasal (EE) transsphenoidal surgery is an important surgical approach to the treatment of sellar pathology, particularly for pituitary adenomas. Risk factors for the radiographic recurrence of pituitary adenomas resected using a purely endoscopic approach have not been established. This study investigates outcomes and identifies risk factors for recurrence following EE transsphenoidal surgery for pituitary adenoma.

Industry progress report on neuro-oncology: Biotech update 2013.

For the second time, The Brain Tumor Center of the Weill Cornell Brain and Spine Center, in collaboration with Voices Against Brain Cancer, hosted The Brain Tumor Biotech Summit in New York City in June 2013. After a very successful first summit in 2012, this innovative event has established a platform for intensive networking between neuro-oncologists, neurosurgeons, neuroscientists, members of the biotechnology and pharmaceutical communities, members of the financial community and leaders of non-profit organizations. This year's summit highlighted dendritic cell vaccines, novel antibody, heat shock protein and targeted therapies as well as exosome technologies, MRI-guided therapies and other novel drug delivery tools.
