Magnetic Resonance Imaging (MRI) Guided Stereotactic Adaptive Radiotherapy for Targeting Abdominal Cancer

The treatment planning protocol follows the UK SABR Consortium Guidelines. Patients will be prescribed the maximum isotoxic dose achievable while meeting normal organ tolerances (normal liver, kidney, spinal cord, stomach, duodenum, small and large bowel, heart, lungs, chest wall). The lowest acceptable SABR doses are indicated in the dose range Table within the protocol. The maximum dose/fraction also indicates the maximum the dose can be escalated to for each adaptive session on the MRI-Linac.
