European Association of Nuclear Medicine: For tumor patients the timely choice of the appropriate therapy is of vital importance.Nuclear medical methods such as PET (positron emission tomography) allow not only for targeting the tumor but also for assessing the treatment outcome soon after therapy onset. This enables doctors to change treatment if necessary and adapt it to the specific conditions and needs of their patients. A non-responder patient can be identified very soon after therapy onset so that non-effective chemotherapy can be immediately stopped, reducing adverse side effects through inefficient toxicity and enabling an early salvage approach, for example by shifting to a different drug or to radiotherapy.
