RATIONALE: Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them.
PURPOSE: This phase II trial is studying how well bevacizumab works in treating patients with recurrent or progression meningiomas.
I. To determine the efficacy of bevacizumab in patients with recurrent or progressive benign and atypical/malignant meningiomas, despite prior therapy, as measured by six-month progression-free survival.
I. To describe the response rate and overall-survival in this patient population.
II. To evaluate the safety profile of bevacizumab in patients with recurrent meningiomas.
III. To perform an exploratory study in patients with hemangioblastoma and hemangiopericytoma.
IV. To assess tissue for VEGF and VEGFR to correlate with response. An exploratory analysis of HER-2 will be performed.
Patients receive bevacizumab IV over 30-90 minutes every 2 weeks for 6 months. Patients may then receive bevacizumab IV every 3 weeks for up to 12 months. Treatment continues in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed every 3 months for 2 years.

A recent study by Plotkin et al. showed that bevacizumab (Avastin) treatment was followed by clinically meaningful hearing improvement, tumor-volume reduction, or both in some, but not all...
RATIONALE: Current therapies for adults with a recurrent/residual Neurofibroma or Schwannoma provide limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy su...
Previous studies have shown that vertigo is the symptoms that mostly affect quality of life in patients with vestibular schwannoma. There is still limited knowledge as to why some patients...
Surgical removal of vestibular schwannoma causes acute vestibular symptoms, including postoperative vertigo and oscilopsia due to nystagmus. In general, the dominant symptom postoperativel...
Response Prediction after Gamma Knife Surgery (GKS) in Patients with Vestibular Schwannoma using Dynamic Contrast-Enhanced (DCE) MR Imaging
Schwannoma is an uncommon tumor of nerve sheath that arises from any peripheral, cranial, or autonomic nerve. Only 4% of head and neck schwannomas originate from the sinonasal tract, and a finding of ...
The schwannoma of the trochlear nerve is rare and originates mostly from the distal parts in interpeduncular cistern. Lesion of the proximal segment in the inferior pineal region is extremely rare. Be...
ABP 215 is a biosimilar product to bevacizumab. Bevacizumab acts by binding to vascular endothelial growth factor A, inhibiting endothelial cell proliferation and new blood vessel formation, thereby l...
Following the seminal work by Dubois et al. (Nat. Commun. 8, 14871 (2017)), we study a double-zero-index acoustic metamaterial with triangular lattice. By varying the height and diameter of air scatte...
Bevacizumab-loaded nanoparticles (B-NP) were prepared by a desolvation process followed by freeze-drying, without any chemical, physical or enzymatic cross-linkage. Compared with typical HSA nanoparti...
A benign SCHWANNOMA of the eighth cranial nerve (VESTIBULOCOCHLEAR NERVE), mostly arising from the vestibular branch (VESTIBULAR NERVE) during the fifth or sixth decade of life. Clinical manifestations include HEARING LOSS; HEADACHE; VERTIGO; TINNITUS; and FACIAL PAIN. Bilateral acoustic neuromas are associated with NEUROFIBROMATOSIS 2. (From Adams et al., Principles of Neurology, 6th ed, p673)
A scientific tool based on ULTRASONOGRAPHY and used not only for the observation of microstructure in metalwork but also in living tissue. In biomedical application, the acoustic propagation speed in normal and abnormal tissues can be quantified to distinguish their tissue elasticity and other properties.
Diagnostic measurement of the nose and its cavity through acoustic reflections. Used to measure nasal anatomical landmarks, nasal septal deviation, and nasal airway changes in response to allergen provocation tests (NASAL PROVOCATION TESTS).
An anti-VEGF recombinant monoclonal antibody consisting of humanized murine antibody. It inhibits VEGF receptors and prevents the proliferation of blood vessels.
All tumors in the GASTROINTESTINAL TRACT arising from mesenchymal cells (MESODERM) except those of smooth muscle cells (LEIOMYOMA) or Schwann cells (SCHWANNOMA).
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...
