Patient-reported outcome (PRO), which is directly obtained from patients, is a multidimensional measure to evaluate the health condition of a patient. The obtained data give evidence of effectiveness from patients' point of view. This article reviews the application of PRO in the study of cancer. The application of PRO is studied from aspects, such as evaluating cancer clinical trials, formulating health policies, evaluating adverse events, evaluating compliance, approving new drugs, and studying the relation between health-related quality of life and PRO.
