Introduction Patient-reported outcome (PRO) measures serve to capture vital patient information not otherwise obtained by primary study endpoints. This paper examines how PROs are utilized as endpoints in industry-sponsored metastatic breast cancer clinical trials. Methods A search was conducted in the clinicaltrials.gov web site for trials involving common treatments for metastatic breast cancer. Thirty-eight clinical trials were identified which included a PRO endpoint in the study, and data were extracted and summarized. Results Overall, 17 unique PRO questionnaires and 14 concepts of measurement were identified as secondary or exploratory endpoints. The Functional Assessment of Cancer Therapy—Breast was the most frequently utilized questionnaire, commonly implemented to assess quality of life. The EORTC QLQ-C30 was also frequently used to measure quality of life or pain. Conclusion This review shares insights into the role of PROs in trials for metastatic breast cancer from which treatment developers and other stakeholders can enhance successful implementation of the patient voice into future trials.
