Filter by: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....
This study is designed to investigate belzutifan as a treatment for VHL disease associated RCC.
The purpose of this study is to learn more about the growth of brain and spinal cord tumors and cysts that develop in association with them in patients with von Hippel-Lindau disease. It will examine how fast the tumors grow and try to determine what factors (for example, puberty , pregnancy, menopause, blood proteins, etc.) affect their growth. Patients between the ages of 8 and 75 years who are enrolled in NIH s study of von Hippel-Lindau disease may be eligible for this 5-year study. Participants will have magnetic resonance imaging (MRI) of the brain and spinal cord and a thorough neurological history and examination at the start of the study. A blood sample will be taken for analysis of factors (hormones or other proteins) that may predict tumor growth. Follow-up clinic visits every 6 months will include a physical and neurological examination, blood tests, and MRI scans of the brain and spine. If symptoms or tumor growth requires more frequent follow-up, scans will be done at 3-month intervals. Surgical removal of brain and spinal cord tumors is currently the treatment of choice when these lesions cause neurological problems. A better understanding of which tumors are likely to grow and which will remain stable may help guide physicians in treatment decisions and avoid unnecessary procedures. ...
