Underrepresented Minority Composition of Invited Panelists at the 2021 ASTRO Annual Meeting

The American Society for Radiation Oncology (ASTRO) Annual Meeting is one of the primary venues for radiation oncologists to present new research, network, and share innovations. In this brief report, we describe the racial representation of invited physician speakers at the Annual Meeting relative to the specialty.

The program list of all invited educational sessions and panel speakers in the ASTRO annual meetings from 2021 was accessed via the ASTRO website. Race was determined by a combination of facial recognition and Internet investigation. Speakers and panels were divided by race and specialty. Underrepresented in medicine (URiM) was defined as Black race and/or Hispanic ethnicity.

We identified 182 cumulative speaking panels at the 2021 ASTRO annual meeting and 960 individuals who filled these panels. The majority of speakers were of White race (57%), followed by Asian race (34.2%). URiM speakers made up approximately 8.6% of speakers and were mostly congregated in diversity, equity, and inclusion in health care (DEI) panels. A total of 15.6% of panels were White-only, and 14.8% of panels had at least 1 URiM member. URiM race speakers were mostly congregated in DEI panels, comprising 44.9% of DEI speaker positions and 4.1% of non-DEI speaker positions; this difference reached statistical significance (P < .0001).

The proportion of underrepresented minorities receiving panel invitations at ASTRO remains minimal and is virtually nonexistent outside of DEI-related panels. Targeted efforts to increase URiM representation will be needed to make tangible progress on this issue, just as they have yielded progress on increasing gender diversity in panel invitations.
