Filter by: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 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 purpose of this study is to determine whether PTK787/ZK 222584 is effective in treating hemangioblastoma of the brain and/or retina in patients with von Hippel-Lindau disease. The study will also assess safety and tolerability of PTK787/ZK 222584, and changes in markers of angiogenesis (new blood vessel growth).
