Brain tumors are difficult to diagnose and treat. Neurologist Tobias Weiss is developing an innovative method that uses blood samples and extracellular vesicles to detect tumors at an early stage and monitor them more effectively.
To help patients faster and more precisely, neurologist Tobias Weiss is working on an innovative method that can provide indications of brain tumors based on blood samples. His research focuses on extracellular vesicles – tiny particles that contain important information about the tumor. This groundbreaking technology could revolutionize diagnostics and offer a more cost-effective, less invasive alternative to current procedures such as surgery and imaging.
New diagnostic methods
Around 2000 people are diagnosed with a brain tumor in Switzerland every year. Tobias Weiss and his team are currently developing and testing new diagnostic methods that use extracellular vesicles to detect tumors at an early stage and monitor their progression. Initial results show a promising accuracy of over 90 percent in differentiating between patients with cancer and healthy patients. In addition to diagnostics, they are also testing innovative therapies that can be specifically tailored to the tumor characteristics of individual patients.
Interdisciplinary cooperation with potential
The interdisciplinary project of the University of Zurich, ETH Zurich and University Hospital Zurich is supported by national and international partners. The aim is to integrate the research results into a mobile device that can efficiently isolate vesicles from the blood. This means that the method could be used not only for brain tumors, but also for other types of cancer and diseases. The research is still in the validation process, but the potential for widespread application in oncology and beyond is enormous.
