PET/CT predicts survival outcomes in immunotherapy patients


In this study of 51 patients with melanoma on immunotherapy, the results of a PET/CT scan with the radiolabeled sugar molecule FDG, within the first few months after starting the treatment, predicted 3 and 5 year survival rates. Why is this important? If physicians know early that a patient is not responding adequately to immunotherapy, they can augment or change treatment with the goal of improving long term survival.
