Propranolol and Von Hippel-Lindau Disease
Hemangioblastoma of CNSVon Hippel-Lindau DiseasePropranolol (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.

The primary objective of the study is to evaluate the objective response rate (ORR) of belzutifan per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR).
68Ga-NY104 PET/CT in Von Hippel-Lindau Disease
Von Hippel-Lindau DiseaseThis is a prospective, single-center, single-arm, diagnostic phase 2 study in patients with von Hippel-Lindau disease. VHL disease is a rare syndrome characterized by VHL gene mutation and HIF activation. Although genetic testing is available, the manifestations of the syndrome are protean; therefore, imaging plays a crucial role in the identification of abnormalities and subsequent follow-up of lesions. For now, conventional imaging serves as the main radiologic modality in the characterization of VHL disease. In this study, we aim to evaluate the sensitivity of 68Ga-NY104 PET/CT in patients with VHL disease. 68Ga-NY104 is a novel small molecule PET tracer targeting carbonic anhydrase IX, which is a down-streaming target of HIF and overexpressed in HIF activation. 68Ga-NY104 PET/CT is likely to function as a sensitive imaging tool to identify VHL-related tumors and to impact patient management if additional lesions are identified. The hypotheses of this study are that 68Ga-NY104 PET/CT can be used as an effective imaging modality in VHL syndrome with high sensitivity 68Ga-NY104 PET/CT may detect lesions that are missed on conventional imaging and can result in management impact. A total of 19 patients will be recruited at Peking Union Medical College Hospital. As an exploratory end-point, a 68Ga-NODAGA-LM3 PET/CT sub-study will be performed in patients with evidence of neuroendocrine tumors.

Natural History and Management of Von Hippel-Lindau (VHL) Associated Pancreatic Neuroendocrine Tumors...
VHL Pancreatic Neuroendocrine TumorsVon Hippel-Lindau Disease1 moreBackground: People with von Hippel-Lindau (VHL) can have problems with a variety of organs, such as the pancreas. The disease can cause tumors of the pancreas. This can result in life-threatening complications. Researchers want to learn more about these pancreatic tumors and how to better detect them. This may help them design better future treatment and care for people with VHL disease. Objective: To better understand VHL disease that affects the pancreas and to test whether adding a certain type of scan (68-Gallium DOTATATE PET/CT) can further detect tumors. Eligibility: People ages 12 and older with VHL that causes tumors and cysts to grow in the pancreas Design: Participants will be screened with their medical records and imaging studies. Participants will have an initial evaluation: Participants will have their body examined by different doctors. This will depend on what types of symptoms they have. Participants will have blood and urine tests Participants will have images made of their body using one or more machines: They made have a CT or PET/CT scan in which they lie on a table that moves through a big ring. They may have an MRI in which they lie on a table that moves into a big tube. They may have an ultrasound that uses a small stick that produces sound waves to look at the body. After the first visit, participants will be asked to return to the NIH. Some of the tests performed at the first visit will be repeated. Depending on their disease status, visits will be once a year or every 2 years for life.
Use of Tracking Devices to Locate Abnormalities During Invasive Procedures
AdenocarcinomaProstate Neoplasms3 moreThis study will evaluate the accuracy and effectiveness of an experimental tracking device for locating abnormalities during invasive procedures, such as biopsy or ablation, that cannot easily be visualized by usual imaging techniques, such as computed tomography (CT) scans or ultrasound. Some lesions, such as certain liver or kidney tumors, small endocrine abnormalities, and others, may be hard to find or only visible for a few seconds. The new method uses a needle with a miniature tracking device buried inside the metal that tells where the tip of the needle is located, somewhat like a mini GPS, or global positioning system. It uses a very weak magnet to localize the device like a miniature satellite system. This study will explore whether this system can be used in the future to more accurately place the needle in or near the desired location or abnormality. Patients 18 years of age and older who have a lesion that needs to be biopsied or an ablation procedure that requires CT guidance may be eligible for this study. Candidates are screened with a medical history and review of medical records, including imaging studies. Participants undergo the biopsy or ablation procedure as they normally would, with the following exceptions: some stickers are placed on the skin before the procedure and a very weak magnet is placed nearby. The needles used are similar to the ones that would normally be used except that they contain a metal coil or spring buried deep within the needle metal. The procedure involves the following steps: Small 1-cm plastic donuts are place on the skin with tape. A planning CT scan is done. The CT scan is sent to the computer and matched to the patient's body location with the help of a very weak magnet. The needle used for the procedure is placed towards the target tissue or abnormality and the "smart needle" location lights up on the old CT scan. A repeat CT is done as it normally is to look for the location of the needle. After the procedure the CT scans are examined to determine how well the new tool located the needle in the old scan.

Kidney CancerUrologic Malignant Disorders3 moreWe will investigate the clinical manifestations and molecular genetic defects of heritable urologic malignant disorders. Families with urologic malignancy with known or suspected genetic basis will be enrolled. Affected individuals or individuals suspected of having a germline urologic malignant disorder will undergo periodic clinical assessment and genetic analyses for the purpose of: 1) definition and characterization of phenotype, 2) determination of the natural history of the disorder, and 3) genotype/phenotype correlation. Genetic linkage studies may be performed in situations in which the genetic basis of the disorder has not been elucidated.
