Research priorities in metastatic breast cancer: A James Lind Alliance Priority Setting Partnership.

Breast cancer remains the most common cancer among women, and the second most common cause of cancer death. With advances in treatment, women are living longer, in some cases many years, with metastatic breast cancer (MBC). These advances are a direct result of research, however, many studies are primarily researcher or industry led, with minimal input from patients and caregivers. The James Lind Alliance (JLA) brings patients, caregivers, and clinicians together in priority setting partnerships (PSPs) to determine key priorities in research. In this study, we utilized the JLA approach to identify unanswered questions on MBC from patient and clinical perspectives and prioritized to reach a top 10. Following the established JLA approach, MBC patients, caregivers, and health care professionals (HCPs) were surveyed to elicit their questions regarding MBC. Research questions were generated from survey responses, and following literature review to ensure the questions were currently not completely answered, an interim prioritization survey was conducted to identify a shortlist of questions taken to a final consensus meeting. One thousand, one-hundred and ninety-four responses were collected from 668 individuals, which were refined into 62 unique unanswered questions. The interim prioritization survey was completed by 174 individuals, and the top 27 questions were taken to a final meeting to determine by consensus the top 10. The top 10 questions cover a wide range of research questions, identified by valuable stakeholders as being priorities. This list can be used to inform prioritization and funding of future MBC research.
