RATIONALE: LMB-7 immunotoxin can locate tumor cells and kill them without harming normal cells.
PURPOSE: Phase I trial to study the effectiveness of LMB-7 immunotoxin in treating patients who have leptomeningeal metastases metastases.
OBJECTIVES: I. Determine the toxicity of intrathecal LMB-7 immunotoxin in patients with leptomeningeal metastases. II. Identify objective therapeutic responses in this group of patients.
OUTLINE: This is a dose escalation study. Patients receive LMB-7 intrathecally on days 1, 3, and 5. Treatment may be repeated every 4 weeks if the patient does not demonstrate HAMA neutralizing antibodies to PE-38 in CSF, has stable or responding disease, and has not experienced greater than grade II toxicity. Three to six patients are entered at each dose level. Dose escalation continues until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience grade 3 or worse toxicity or a neuroradiology toxicity score of 10 or greater.
PROJECTED ACCRUAL: Approximately 15 to 24 patients will be accrued over one year.

We present a national surveillance report on malignant primary brain and other central nervous system (CNS) tumors diagnosed in the Canadian population in 2009-2013.
Studies of epidemiology, treatment modalities, and outcomes of childhood central nervous system (CNS) tumors in Sudan are scarce. To address this shortcoming, we evaluated baseline information about t...
Several Phase II and III clinical trials have demonstrated that immunotherapy can induce objective responses in otherwise refractory malignancies in tumors outside the central nervous system. In large...
Hemangioblastomas (HBs) are benign vascular tumors of the central nervous system and histologically contain abundant microvessels. Therefore, they clinically exhibit vascular malformation-like charact...
Central nervous system (CNS) tumors are a group of neoplasms that originate from various cells in the CNS. The increasing incidence and prevalence of this type of tumor in developing countries are str...
Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.
A group of malignant tumors of the nervous system that feature primitive cells with elements of neuronal and/or glial differentiation. Use of this term is limited by some authors to central nervous system tumors and others include neoplasms of similar origin which arise extracranially (i.e., NEUROECTODERMAL TUMORS, PRIMITIVE, PERIPHERAL). This term is also occasionally used as a synonym for MEDULLOBLASTOMA. In general, these tumors arise in the first decade of life and tend to be highly malignant.

Diseases of the parasympathetic or sympathetic divisions of the AUTONOMIC NERVOUS SYSTEM; which has components located in the CENTRAL NERVOUS SYSTEM and PERIPHERAL NERVOUS SYSTEM. Autonomic dysfunction may be associated with HYPOTHALAMIC DISEASES; BRAIN STEM disorders; SPINAL CORD DISEASES; and PERIPHERAL NERVOUS SYSTEM DISEASES. Manifestations include impairments of vegetative functions including the maintenance of BLOOD PRESSURE; HEART RATE; pupil function; SWEATING; REPRODUCTIVE AND URINARY PHYSIOLOGY; and DIGESTION.
The main information-processing organs of the nervous system, consisting of the brain, spinal cord, and meninges.
A vascular anomaly characterized by a radial or wedge-shaped arrangement of dilated VEINS draining into a larger vein in the brain, spinal cord, or the meninges. Veins in a venous angioma are surrounded by normal nervous tissue, unlike a CENTRAL NERVOUS SYSTEM CAVERNOUS HEMANGIOMA that lacks intervening nervous tissue. Drainage of venous angioma is fully integrated with the body's venous system, therefore, in most cases there is no clinical signs and rare bleeding.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
