Bridging that gap: a qualitative study of perceptions of equality, diversity and inclusivity in colorectal surgery in the UK and Ireland.

BACKGROUND: There is a growing recognition on the importance of equality, diversity and inclusion (EDI) within surgery and the need to diversify the surgical community and its various organisations, in a bidto reflect the diverse populations they serve. To create, sustain and encourage a diverse surgical workforce requires an in-depth understanding of the current makeup of key surgical institutions, relevant issues pertaining to EDI and appropriate solutions and strategies to ensure tangible change. OBJECTIVES: Following on from the recent Kennedy Review into Diversity and Inclusion commissioned by the Royal College of Surgeons of England, the aim of this qualitative study was to understand the EDI issues which affected the membership of the Association of Coloproctology of Great Britain and Ireland, while seeking appropriate solutions to address them. DESIGN: Dedicated, online and qualitative focus groups. PARTICIPANTS: Colorectal surgeons, trainees and nurse specialists were recruited using a volunteer sampling strategy. METHODS: A series of online, dedicated, qualitative focus groups across the 20 chapter regions were held. Each focus group was run informed by a structured topic guide. All participants who were given the opportunity to remain anonymous were offered a debriefing at the end. This study has been reported in keeping with the Standards for Reporting Qualitative Research. RESULTS: Between April and May 2021, a total number of 20 focus groups were conducted, with a total of 260 participants across 19 chapter regions. Seven themes and one standalone code pertaining to EDI were identified: support, unconscious behaviours, psychological consequences, bystander behaviour, preconceptions, inclusivity and meritocracy and the one standalone code was institutional accountability. Five themes were identified pertaining to potential strategies and solutions: education, affirmative action, transparency, professional support and mentorship. CONCLUSION: The evidence presented here is of a range of EDI issues which affect the working lives of those within colorectal surgery in the UK and Ireland, and of potential strategies and solutions which can help build a more inclusive, equitable and diverse colorectal community.

Spatial immune profiling of the colorectal tumor microenvironment predicts good outcome in stage II patients.

Cellular subpopulations within the colorectal tumor microenvironment (TME) include CD3+ and CD8+ lymphocytes, CD68+ and CD163+ macrophages, and tumor buds (TBs), all of which have known prognostic significance in stage II colorectal cancer. However, the prognostic relevance of their spatial interactions remains unknown. Here, by applying automated image analysis and machine learning approaches, we evaluate the prognostic significance of these cellular subpopulations and their spatial interactions. Resultant data, from a training cohort retrospectively collated from Edinburgh, UK hospitals (n = 113), were used to create a combinatorial prognostic model, which identified a subpopulation of patients who exhibit 100% survival over a 5-year follow-up period. The combinatorial model integrated lymphocytic infiltration, the number of lymphocytes within 50-µm proximity to TBs, and the CD68+/CD163+ macrophage ratio. This finding was confirmed on an independent validation cohort, which included patients treated in Japan and Scotland (n = 117). This work shows that by analyzing multiple cellular subpopulations from the complex TME, it is possible to identify patients for whom surgical resection alone may be curative.
