49 Key Opinion Leader Interviews We interviewed 59 KOLs representing the breast cancer patient advocacy, academic, government, pharmaceutical industry, and nonprofit sectors. The goal of these interviews was to gain input on urgent priorities, gaps, and opportunities in MBC research. We identified our list of interviewees from the leadership of our own Alliance member organizations and from the MBC Grants Dataset by identifying those scientists who were listed as principal investigator on 6 or more grants. A complete list of the KOLs interviewed is in Appendix 2. Many of the experts cautioned against specifically focusing on the list of 7 questions we had developed, noting that not all possible or exciting target areas were listed. However, the questions did elicit informative responses. The recurring themes that emerged from the 3 or more respondents are summarized in Table 5.
