Filter by:Propranolol (beta-blocker), is successfully used for the treatment of infantile hemangiomas, the most common vascular tumor of newborns. The mechanism is related to its anti-angiogenetic and pro-apoptotic effects. Recently, in vitro studies demonstrated that propranolol decreased the expression of target genes of the HIF (hypoxia-inducible factor, of which the VHL gene is the main regulator) pathway in hemangioblastoma cells and affected their viability. The efficacy of propranolol (stabilization of all HB and decrease in serum VEGF levels) was demonstrated in a phase III study, but only in retinal BHs . The only study that evaluated the effect of propranolol on CNS HB was retrospective and involved a limited number of patients. Nevertheless, it showed a decrease in the growth rate of HBs. The investigator therefore propose to carry out a randomized controlled trial to study the effect of propranolol on the growth of CNS HB in patients with VHL disease (von Hippel-Lindau). The hypothesis of the present work is the following: the use of propranolol in VHL patients with CNS HB allows to decrease and/or slow down the tumor growth.
Every new classification depends on its prognostic power and on the type of treatment given. With the rapid evolution of diagnostic methods and the advance in new treatments, there is much less reliable information available on how patients with newly defined brain tumour entities should be treated and what to expect from the current treatments. The goal is to determine whether the new 2021 WHO classification, based on cIMPACT-NOW recommendations, results in more homogeneous patient groups than the old 2016 classification. Furthermore, it will help derive provisional guidelines on how patients with these newly defined tumour entities are best treated. These recommendations will be based on the experience of EORTC investigators with chosen treatments and their experience as reported in this data collection report.
Background: Retinal hemangioblastoma (RH) is a tumor. It grows from the retina in the eye. It can threaten a person s vision. Trans-scleral cryotherapy is used to destroy the tumors and minimize the long-term risks of vision loss. RH is a rare condition, often occurring in people with von Hippel-Lindau disease. There are no clinical trials to study how well the treatment works. Researchers want to study the medical records of people with RH who were treated at the NIH eye clinic to learn more. Objective: To analyze clinical data collected over a 20-year span to study consecutive cases of RH managed with trans-scleral cryotherapy at the NIH. Eligibility: People who took part in NIH natural history protocols for which cryotherapy of RH was performed as a standard care measure. Design: Researchers will collect and study data from participants medical charts. Participants will not be contacted because no new data is needed. Researchers were granted a waiver of informed consent for use of these medical records. To protect patient privacy, participants will be assigned an ID number. Their data will be entered into a spreadsheet in a coded fashion. The key to this code will be kept in a secure file. No patient identifying information will be used in the analysis or the publication....
The study population consists of patients who undergo resection for somatostatin receptor-positive (SSTR-positive) CNS tumors, focusing on meningioma, and including esthesioneuroblastoma, hemangioblastoma, medulloblastoma, paraganglioma, pituitary adenoma, and SSTR-positive systemic cancers metastatic to the brain, such as small cell carcinoma of the lung. The study indication is to determine the diagnostic utility of 68Ga-DOTATATE PET/MRI in the diagnosis and management of patients with SSTR-positive CNS tumors, specifically whether 68Ga-DOTATATE PET/MRI demonstrates utility distinguishing between tumor recurrence and post-treatment change. To date, the utility of Ga-68-DOTATATE PET/MRI in meningioma has not been explored. Investigators have over the past 3 months been able to accrue the largest case series of presently 12 patients in whom Ga-68-DOTATATE PET/MRI demonstrated utility in the assessment of meningioma, including assessment for postsurgical/postradiation recurrence, detection of additional lesions not visualized on MRI alone, and evaluation of osseous invasion. Based on this initial experience, investigators intend to study the impact of Ga-68-DOTATATE PET/MRI in the assessment of the extent of residual tumor in patients status post meningioma resection, specifically in patients in whom tumor location limits resectability, patients with World Health Organization (WHO) grade II/III disease, and patients with history of stereotactic radiosurgery (SRS) who develop postradiation change.
Von Hippel-Lindau (VHL) disease is a severe autosomal dominant genetic disorder (with almost complete penetrance) that predisposes to many tumors including some associated with a poorer outcome. Clear cell renal cell carcinoma (CCRCC) is the leading cause of mortality. The diagnosis of VHL disease may be challenging because tumors have an asynchronous and multi-organ development and there is often no apparent hereditary context. As it is admitted that VHL disease is underdiagnosed, some countries have decided to recall patients presenting one of the potentially VHL disease-associated tumors to screen them for VHL mutation. Screening is currently recommended in guidelines but many patients may have not been previously screened. Hemangioblastoma (HB) of the Central nervous system (CNS) is one of the typical VHL tumors and up to 20% of patients with HB show VHL mutation. VHL diagnosis in this population enables the diagnosis of other tumor types at an early stage of development since HB is chronologically the second tumor occurring during the VHL disease history. But it raises critical problems and questions: difficult announcement of a potentially severe disease and psychosocial dimension related to inheritance of the disease.
Background: - Von Hippel-Lindau (VHL) disease is a rare gene disease. People with VHL often have a brain tumor called hemangioblastoma. Standard treatment for these tumors is risky surgery. Researchers want to find new ways to treat people who have the tumors. They want to see if a drug that fights other cancers might slow the growth of hemangioblastomas in some people with VHL. Some people with VHL have mutations that make abnormal proteins. Tumors form in such people because the abnormal protein is broken down quickly. The cancer drug may work in these tumors by preventing breakdown of protein. Objective: - To study how the drug vorinostat affects hemangioblastomas in people with VHL. Eligibility: - Adults at least 18 old with hemangioblastomas from VHL. Design: - Participants must already be in study 03-N-0164. They must have tumor surgery scheduled. - Participants must stop taking most medications 14 days before surgery. - One week before surgery, participants will enter the hospital. They will be screened with medical history and physical and neurological exams. They will give blood and urine samples. Participants will have an electrocardiogram. For this test, small sticky patches are put on the arms, legs, and chest. Participants will lie still for a few minutes while a machine records heart rate and rhythm. - Participants will take one vorinostat by mouth each day for 7 days. - Participants will have blood drawn during the week to check for any side effects. - Participants will have their tumor removed in surgery. Researchers will study the tumor tissue for the effects of the study drug. - A nurse will call participants 1 month after surgery to check for side effects.
Von Hippel-Lindau (VHL) disease is an inherited syndrome manifested by a variety of benign and malignant tumors. Hemangioblastomas are the most common lesion associated with VHL disease affecting 60-84% of patients with a mean age at diagnosis of 29 years. Standard treatment for this disease is by surgery or radiotherapy. No approved systemic therapy yet exists. Patients with VHL have an increased growth factor production, specifically vascular endothelial growth factor (VEGF), resulting in angiogenesis (growth of blood vessels). Studies show that Bevacizumab inhibits the growth of VEGF protein and will block the VEGF-driven angiogenesis and result in stabilization and regression of hemangioblastomas in VHL disease patients. The dose of bevacizumab will be 10 mg/kg every two weeks for up to 6 months.
Von Hippel Lindau disease (VHLD) is an inherited syndrome characterized by vascular malformations, kidney cancer, adrenal gland and pancreas tumors. The VHL protein is not functional in the different disease associated lesions which results in production of high amounts of vascular endothelial growth factor (VEGF). Currently there are no clinical, radiographic or molecular markers that can predict the natural history of a given lesion. With 89Zr-bevacizumab positron emission tomography (PET) scanning, VEGF can be visualized and quantified. The investigators hypothesize that 89Zr-bevacizumab PET imaging is a useful tool to predict the behaviour of disease associated lesions in patients with VHLD. Adult patients with VHLD who have had routine magnetic resonance imaging (MRI) scans of central nervous system (CNS) and abdomen will undergo a 89Zr-bevacizumab PET scan. MRI will be repeated within 12 months.
The purpose of this study is to find out what effects, good and/or bad, sunitinib has on patients and their tumors. At this time, no drugs are routinely used to treat meningioma, hemangioblastoma or hemangiopericytoma. Only surgery and radiation therapy are known to be useful. Sunitinib is a drug approved for advanced kidney cancer. Sunitinib is also being studied for other tumors. It may be useful in the treatment of brain tumors because it can prevent formation of new blood vessels that allow tumor cells to survive and grow.
The goal of this clinical research study is to learn if sunitinib malate (SU011248) can help to control VHL. The safety of this drug will also be studied. Primary objectives: - Evaluate safety of treatment with SU011248/sunitinib malate (50 mg daily dose for 4 weeks, then 2 weeks off) for 6 months in patients with Von Hippel-Lindau Syndrome (VHL) who have a measurable lesion undergoing surveillance Secondary objectives: - Evaluate efficacy of treatment with SU011248/sunitinib malate (50 mg daily dose for 4 weeks, then 2 weeks off) for 6 months in patients with VHL who have a measurable lesion undergoing surveillance Correlative objectives: - Evaluate quality of life of SU011248/sunitinib malate therapy in VHL patients - Evaluate peripheral blood lymphocyte receptor phosphorylation in VHL patients taking SU011248/sunitinib malate (optional procedure) - Correlate results of dynamic contrast-enhanced and diffusion weighted MRI and dynamic contrast enhanced CT with response and explore findings suggestive of surrogates of early response (optional procedure)
