What is the purpose of this trial?

The trial aims to understand how von Hippel-Lindau (VHL) disease affects the pancreas by studying pancreatic tumors. Researchers seek to determine if a 68-Gallium DOTATATE PET/CT scan can more effectively detect these tumors. Success in this area could lead to improved treatments and care for individuals with VHL. The trial seeks participants aged 12 and older who have VHL and experience tumors or cysts in their pancreas. Participants will undergo various scans and tests to monitor their condition over time. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, allowing participants to contribute to advancements in VHL care.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What prior data suggests that the 68-Gallium DOTATATE scan is safe for detecting pancreatic tumors in VHL patients?

Research has shown that 68-Gallium DOTATATE has been safely used to help doctors visualize neuroendocrine tumors. This imaging agent highlights certain tumors, making them easier to detect.

Reports of serious side effects with 68-Gallium DOTATATE have not emerged. However, as this trial is in an early stage, researchers are still carefully studying the treatment's safety. Participants should ask questions and discuss any concerns with the trial team, who can provide detailed information about what to expect. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the use of 68-Gallium DOTATATE scans for Von Hippel-Lindau (VHL) syndrome because this imaging agent offers a new way to monitor pancreatic neuroendocrine tumors. Unlike traditional imaging methods, 68-Gallium DOTATATE binds specifically to somatostatin receptors, which are often overexpressed in these tumors, allowing for more precise detection and monitoring. This could potentially lead to earlier interventions and better management of tumor progression in VHL patients, setting it apart from the standard imaging techniques typically used.

What evidence suggests that the 68-Gallium DOTATATE scan is effective for detecting pancreatic tumors in VHL patients?

Research has shown that 68-Gallium DOTATATE PET/CT scans effectively detect tumors in individuals with von Hippel-Lindau (VHL) disease. In a study involving 36 VHL patients, this scan identified more tumors than traditional CT and MRI scans, revealing additional tumors that other methods missed. The trial will compare two approaches: one group will undergo yearly 68-Gallium DOTATATE PET/CT research scans, while the other group will be observed without these scans. This suggests that the 68-Gallium DOTATATE scan might be superior for early tumor detection, which is crucial for managing VHL. By identifying more tumors, this scan could enhance care and treatment planning. ^{1 2 3 6 7}

Ga-68 somatostatin receptor PET/CT imaging is effective for diagnosing and managing various malignancies associated with Von Hippel-Lindau (VHL) disease, which includes a range of tumors such as hemangioblastomas and pheochromocytomas.

This imaging technique serves as a comprehensive tool for evaluating and monitoring the multiple tumor types that can arise in patients with VHL disease, highlighting its potential as a 'one-stop-shop' for clinical management.

68Ga-DOTANOC PET/CT imaging can reveal somatostatin receptor expression in various conditions, including in cases of Von Hippel-Lindau syndrome, which is linked to multiple tumor types.

In a specific case, the imaging technique showed tracer uptake in swollen eyelids of a patient suspected of having Von Hippel-Lindau syndrome, but clinical examination later confirmed the condition as viral conjunctivitis, highlighting the importance of accurate diagnosis.

In a study of 14 patients with Von Hippel-Lindau (VHL) disease, the 68Ga-DOTANOC PET/CT scan successfully detected a total of 67 lesions across various sites, demonstrating its efficacy in identifying both benign and malignant tumors associated with this hereditary condition.

The 68Ga-DOTANOC PET/CT scan may serve as a convenient one-stop imaging solution for VHL patients, potentially replacing multiple separate imaging tests, thus saving time and reducing costs for patients undergoing screening and follow-up evaluations.

In a study involving 36 patients with von Hippel-Lindau (VHL) disease, 68Ga-DOTATATE PET/CT demonstrated a higher detection rate of lesions compared to traditional imaging methods like CT and MRI, making it a promising tool for monitoring tumors associated with VHL.

68Ga-DOTATATE PET/CT not only showed superior detection capabilities but also offered lower radiation exposure, suggesting it could be a safer and more effective option for the surveillance of VHL-related tumors.

A rare case of metastatic renal cell carcinoma was identified in a 66-year-old man with von Hippel-Lindau syndrome, showing 68Ga-DOTATATE uptake in multiple locations, including the pancreas and spine.

The presence of 68Ga-DOTATATE avidity in VHL-associated cancers can influence clinical decision-making, highlighting the importance of this imaging technique in detecting and managing such rare metastatic presentations.

In a study of 81 patients with neuroendocrine tumors (NETs), Ga-68 DOTATATE PET/CT was more effective than F-18 FDG PET/CT in detecting positive scans in patients with low and intermediate-grade tumors, with 82.1% of DOTATATE scans positive compared to 54.5% for FDG (P = 0.04).

For high-grade, poorly-differentiated NETs, both DOTATATE and FDG PET/CT scans were equally effective, with all patients showing positive results, indicating that while DOTATATE is superior for lower-grade tumors, it does not provide additional benefits for high-grade tumors compared to FDG.

Post FDA approval analysis of 200 gallium-68 DOTATATE imaging: A retrospective analysis in neuroendocrine tumor patients. Chauhan, A., El-Khouli, R., Waits, T., et al.[2023]

In a study of 20 patients with von Hippel-Lindau disease, (68)Ga-DOTATOC PET/CT detected pancreatic neuroendocrine tumors (pNETs) in 55% of patients, outperforming traditional imaging methods like CT and MRI, which identified only 45%.

The study suggests that (68)Ga-DOTATOC PET/CT is a more effective screening tool for pNETs in vHLD patients compared to the previously recommended (111)In-octreoscan, as it identified a higher proportion of tumors without any patients showing progressive disease during follow-up.
