Correlating the Tumoral Metabolic Progression Index to Patient’s Outcome in Advanced Colorectal Cancer

The purpose of this study is to assess whether in a population of patients with advanced colorectal cancer for which no known effective therapy is available, measuring the spontaneous evolution of tumoral metabolic progression index by serial FGD PET-CT and Diffusion MRI can show that tumor growth rate is related to the patient’s outcome, and that serial FDG PET-CT and Diffusion MRI are able to measure it.
