Researchers in Germany have successfully conducted the first cancer treatment using a radioactive carbon ion beam (11C) on a mouse with a bone tumor near the spine. This innovative approach allows for the simultaneous treatment and real-time visualization of the treatment beam using positron emission tomography (PET), potentially overcoming limitations in current particle therapy methods. The study, part of the ERC-funded BARB project, showed that the radioactive ion beams produce a stronger PET signal, helping to accurately locate the radiation treatment within the body. The team demonstrated effective tumor control without significant toxicity to surrounding tissues, indicating a promising direction for more precise and adaptive particle therapy in cancer treatment. The findings were published in Nature Physics.
