Real-world evidence research in metastatic colorectal cancer: raising awareness of the need for patient contributions.

Real-world evidence (RWE) research helps determine whether outcomes observed in clinical trials happen in real-life clinical practice. RWE research may help patients receive more appropriate treatment, closer to their needs and wishes. RWE for metastatic colorectal cancer is currently limited. The PROMETCO RWE study is an important example of an ongoing initiative that focuses on patient-reported outcomes in metastatic colorectal cancer. Patients play an active role throughout the RWE research process, including study design, participation and results dissemination. This involvement can encourage greater patient empowerment through active engagement, potentially resulting in various benefits that can lead to improved clinical outcomes. Greater patient engagement can increase involvement in RWE, helping more patients to access the benefits of RWE research. Clinical Trial Registration: NCT03935763 (ClinicalTrials.gov).
