Abstract

Colorectal cancer is one of the most common cancers worldwide. It is the third most common cancer in men and the second in women. The mortality is higher in the less developed regions of the world. There is a tendency in increasing mortality rates for colorectal cancer until 2025 in Brazil, mostly because of the aging process of the population. Besides, there have been incredible advances in systemic therapy for colorectal cancer, which led to the necessity to monitoring therapy in these patients.PET/CT with 18F-FDG is the state of the art in the evaluation of many cancers. However, it has some limitations as some false positive results and difficulty in evaluate locally spread of rectal cancer (T staging). Magnetic Resonance (MR) is the imaging of choice in staging rectal cancer due to its high anatomical resolution. PET/MR is a new technology, which joint the excellent metabolic capacity from PET with the high anatomical resolution from MR.Purpose: The primary outcome of interest of this project is verify the change in management achieved by PET/RM with 18F-FDG in comparison to the standard care of imaging (CT, MRI and 18F-FDG PET/CT), routinelly performed in clinical practice. Methods: In this retrospective observational diagnostic study, it will be studied patients with colorectal cancer already treated. The eletronic medical records of patients will be evaluated to ascertain if any change in management were prompted by PET/MR comparing to the standard care of imaging. The second outcome of interest will be analyze the performance of PET/MR comparing with the standard care of imaging to determinae the precision of oncologic staging.
