[Diversity, equity and inclusion in radiation oncology : where do we stand ?] / Diversité, équité et inclusion en radiothérapie-oncologie : où en sommes-nous ?

INTRODUCTION: The promotion of diversity, equity and inclusion (DEI) is increasingly sought after in healthcare, which is why we wanted to draw up a picture of DEI in radiation oncology and give some ideas on how to contribute to its dissemination. METHOD: This article proposes a non-exhaustive review of the international literature on DEI in radiation oncology, both among health professionals and patients. In addition, this review identifies some implicit cognitive biases and proposes strategies to address them. RESULTS: Most of the proposed publications identify a lack of DEI among radiation oncology staff and document inequities in access to high-quality radiotherapy affecting patients belonging to minority groups. CONCLUSION: Significant disparities exist between genders and ethnic groups within the radiotherapy teams, and in the radiotherapy treatment of patients. Nevertheless, DEI is gaining importance, and a range of initiatives and instruments are being developed to address these disparities.

INTRODUCTION: La promotion de l'équité, de la diversité et de l'inclusion (EDI) est de plus en plus recherchée dans les soins de santé, raison pour laquelle nous avons voulu dresser un tableau de l'EDI en radiothérapie et donner des pistes pour contribuer à sa diffusion. Méthode : Cet article propose une revue non exhaustive de la littérature internationale sur l'EDI en radiothérapie, tant chez les professionnels de la santé que chez les patients. En outre, cette revue relève des biais cognitifs implicites et propose des stratégies pour y remédier. Résultats : La majorité des publications proposées identifient un manque d'EDI parmi les professionnels en radiothérapie, et documentent également des iniquités dans l'accès à une radiothérapie de haute qualité touchant les patients issus de groupes minoritaires. CONCLUSION: D'importantes disparités existent entre genres et groupes ethniques au sein des équipes de radiothérapie ainsi que dans le traitement des patients par radiothérapie. Néanmoins, l'EDI gagne en importance et toute une série d'initiatives et d'instruments pour remédier à ces disparités se développent.

Qualitative Study on Diversity, Equity, and Inclusion Within Radiation Oncology in Europe.

PURPOSE: Organizational culture plays a major role in prioritizing diversity, equity, and inclusion (DEI) objectives by aligning individual values of employees with organizational values. However, effective strategies to create an inclusive organizational culture, in which these values are aligned, remain unclear. The European Society for Radiotherapy and Oncology (ESTRO) launched a qualitative study, as a follow-up of the previous project on DEI that highlighted low levels of inclusion and work engagement among radiation oncology (RO) professionals in Europe. The aim of the present study was to gain an understanding of how DEI could be improved within RO departments by creating a more inclusive organizational culture. METHODS AND MATERIALS: A qualitative research study was conducted by enrolling RO professionals from 4 selected European countries through an open call on the ESTRO platform. Respondents who completed an online survey and met the inclusion criteria, such as experiencing low DEI levels at work, were invited for an online semistructured interview. Interview transcripts were analyzed thematically with an abductive approach via concepts in relation to "DEI," "work engagement," "organizational culture," and "professional values." RESULTS: Twenty-six eligible respondents from Great Britain, Italy, Poland, and Switzerland were interviewed. The thematic analysis identified cases in which limited engagement at work emerged when the personal values of RO professionals conflicted with dominant organizational values, hampering DEI. Three conflicts were found between the following personal versus organizational values: (1) self-development versus efficiency, (2) togetherness versus competition, and (3) people-oriented versus task-oriented cultures. CONCLUSIONS: Awareness of how organizational values can conflict with professionals' values should be raised to improve inclusion and engagement in the workplace. Additionally, efforts should be focused on tackling existing power imbalances that hamper effective deliberation on organizational- versus personal-value conflicts.

Gender-related and geographic trends in interactions between radiotherapy professionals on Twitter.

Background and purpose: Twitter presence in academia has been linked to greater research impact which influences career progression. The purpose of this study was to analyse Twitter activity of the radiotherapy community around ESTRO congresses with a focus on gender-related and geographic trends. Materials and methods: Tweets, re-tweets and replies, here designated as interactions, around the ESTRO congresses held in 2012-2021 were collected. Twitter activity was analysed temporally and, for the period 2016-2021, the geographical span of the ESTRO Twitter network was studied. Tweets and Twitter users collated during the 10 years analysed were ranked based on number of 'likes', 're-tweets' and followers, considered as indicators of leadership/influence. Gender representation was assessed for the top-end percentiles. Results: Twitter activity around ESTRO congresses was multiplied by 60 in 6 years growing from 150 interactions in 2012 to a peak of 9097 in 2018. In 2020, during the SARS-CoV-2 pandemic, activity dropped by 60 % to reach 2945 interactions and recovered to half the pre-pandemic level in 2021. Europe, North America and Oceania were strongly connected and remained the main contributors. While overall, 58 % of accounts were owned by men, this proportion increased towards top liked/re-tweeted tweets and most-followed profiles to reach up to 84 % in the top-percentiles. Conclusion: During the SARS-CoV-2 pandemic, Twitter activity around ESTRO congresses substantially decreased. Men were over-represented on the platform and in most popular tweets and influential accounts. Given the increasing importance of social media presence in academia the gender-based biases observed may help in understanding the gender gap in career progression.

The role of medical physicists in clinical trials across Europe.

INTRODUCTION: The roles and responsibilities of medical physicists (MPs) are growing together with the evolving science and technology. The complexity of today's clinical trials requires the skills and knowledge of MPs for their safe and efficient implementation. However, it is unclear to what extent the skillsets offered by MPs are being exploited in clinical trials across Europe. METHODS: The EFOMP Working Group on the role of Medical Physics Experts in Clinical Trials has designed a survey that targeted all 36 current National Member Organisations, receiving a response from 31 countries. The survey included both quantitative and qualitative queries regarding the involvement of MPs in trial design, setup, and coordination, either as trial team members or principal investigators. RESULTS: The extent of MPs involvement in clinical trials greatly varies across European countries. The results showed disparities between the roles played by MPs in trial design, conduct or data processing. Similarly, differences among the 31 European countries that responded to the survey were found regarding the existence of national bodies responsible for trials or the available training offered to MPs. The role of principal investigator or co-investigator was reported by 12 countries (39%), a sign of efficient collaboration with medical doctors in designing and implementing clinical studies. CONCLUSION: Organisation of specific training courses and guideline development for clinical trial design and conduct would encourage the involvement of a larger number of MPs in all stages of trials across Europe, leading to a better standardisation of clinical practice.

Establishing a benchmark of diversity, equity, inclusion and workforce engagement in radiation oncology in Europe - An ESTRO collaborative project.

BACKGROUND AND PURPOSE: Diversity, Equity and Inclusion (DEI) in the medical workforce is linked to improved patient care and innovation, as well as employee retention and engagement. The European Society for Radiotherapy and Oncology launched a survey to provide a benchmark of DEI and engagement among radiation oncology (RO) professionals in Europe. METHODS: An anonymous survey was disseminated among RO professionals in Europe. The survey collected demographics and professional information, and participants were asked if they felt they belonged to a minority group. A DEI and workforce engagement questionnaire by Person et al. evaluated 8 inclusion factors. A favourable score was calculated by adding the percentage of "strongly agreed" or "agreed" answers. RESULTS: A total of 812 complete responses were received from 35 European countries. 21% of respondents felt they belonged to a minority group, mostly based on race/ethnicity (5.9%), nationality (4.8%) and age (4.3%). Compared to benchmark data from the United States, scores were lower for most inclusion factors, and to a greater extent for minority groups. The overall favourable score was 58% for those belonging to a minority group, significantly lower than for other respondents (71%, p < 0.001). Those belonging to a minority group because of their gender or age had the lowest overall favourable score (47% and 51% respectively). CONCLUSIONS: Our work indicates that actions to improve DEI and workforce engagement among RO professionals in Europe are urgently needed, in particular among minority groups. This would potentially improve employee wellbeing and retention, promoting high quality care and innovation.

Alexithymia and professional quality of life in radiation oncology: The moderator effect of the professional profile.

BACKGROUND AND PURPOSE: Cancer care can be taxing. Alexithymia, a personality construct characterized by difficulties in identifying and describing feeling and emotions, an externally-oriented thinking style and scarcity of imagination and fantasy, is significantly correlated with higher levels of both secondary traumatic stress (STS) and burnout and lower levels of compassion satisfaction in medical professionals in radiation oncology. In this study, we aimed to assess the difference in professional quality of life (QoL) and the association with alexithymia in this multidisciplinary field depending on the specific profession (radiation/clinical oncologist, RO; medical physicist, MP; radiation therapist, RTT). MATERIAL AND METHODS: The study was conducted via an online questionnaire, receiving 1500 submissions between May and October 2018. Alexithymia was assessed via the Toronto Alexithymia Scale (TAS-20) and professional QoL was evaluated using the Professional Quality of Life Scale (ProQoL) version 5. Comparisons between the RO, RTT, and MP groups were performed by ANOVA or MANOVA, followed by Bonferroni corrected ANOVAs for continuous variables, and Pearson's chi-square test for categorical variables. The effect size was determined by calculating partial eta-squared (η2). RESULTS: Profession had a moderator role on the correlation between alexithymia and STS, with RO being at a higher risk than MP and RTT. Further, the results of this study demonstrate the relevant point prevalence of decreased well-being at work even for professional categories such as MP despite the more technical profile and reduced interaction with patients. CONCLUSIONS: This study demonstrates the importance of alexithymia as a factor contributing to decreased professional QoL amongst radiation oncology professionals. Alexithymic ROs are impacted to a higher extent compared to MPs and RTTs by the indirect exposure to patients suffering. It is worth addressing these observations in professional education, aiming to improve QoL for healthcare personnel.

The role of alexithymia and empathy on radiation therapists' professional quality of life.

BACKGROUND AND PURPOSE: Physical and mental well-being are crucial for oncology professionals as they affect performance at work. Personality traits, as alexithymia and empathy, may influence professional quality of life. Alexithymia involves diminished skills in emotion processing and awareness. Empathy is pertinent to the ability to understand another's 'state of mind/emotion'. The PROject on Burn-Out in RadiatioN Oncology (PRO BONO) investigates professional quality of life amongst radiation oncology professionals, exploring the role of alexithymia and empathy. The present study reports on data pertinent to radiation therapists (RTTs). MATERIAL AND METHODS: An online survey targeted ESTRO members. Participants were asked to fill out 3 questionnaires for alexithymia, empathy and professional quality of life: (a) Toronto Alexithymia Scale (TAS-20); (b) Interpersonal Reactivity Index (IRI); (c) Professional Quality of Life Scale (ProQoL). The present analysis focuses on RTTS to evaluate compassion satisfaction (CS), secondary traumatic stress (STS) and Burnout and their correlation with alexithymia and empathy, using generalized linear modeling. Covariates found significant at univariate linear regression analysis were included in the multivariate linear regression model. RESULTS: A total of 399 RTTs completed all questionnaires. The final model for the burnout scale of ProQoL found, as significal predictors, the TAS-20 total score (ß = 0.46, p < 0 0.001), and the individual's perception of being valued by supervisor (ß = -0.29, p < 0.001). With respect to CS, the final model included TAS-20 total score (ß = -0.33, p < 0.001), the Empatic Concern domain (ß = 0.23, p < 0.001) of the IRI questionnaire and the individual's perception of being valued by colleagues (ß = 0.22, p < 0.001). CONCLUSIONS: Alexithymia increased the likelyhood to experience burnout and negatively affected the professional quality of life amongst RTTs working in oncology. Empathy resulted in higher professional fulfillment together with collegaues' appreciation. These results may be used to benchmark preventing strategies and implement organization-direct and/or individual-directed interventions.

Professional quality of life and burnout amongst radiation oncologists: The impact of alexithymia and empathy.

BACKGROUND AND PURPOSE: Different factors may influence the professional quality of life of oncology professionals. Among them, personality traits, as alexithymia and empathy, are underinvestigated. Alexithymia is about deficits in emotion processing and awareness. Empathy is the ability to understand another's 'state of mind'/emotion. The PROject on BurnOut in RadiatioN Oncology (PRO BONO) assesses professional quality of life, including burnout, in the field of radiation oncology and investigates alexithymia and empathy as contributing factors. MATERIAL AND METHODS: An online survey was conducted amongst ESTRO members. Participants completed 3 validated questionnaires for alexithymia, empathy and professional quality of life: (a) Toronto Alexithymia Scale; (b) Interpersonal Reactivity Index; (c) Professional Quality of Life Scale. The present analysis, focusing on radiation/clinical oncologists, evaluates Compassion Satisfaction (CS), Secondary Traumatic Stress (STS) and Burnout and correlates them with alexithymia and empathy (empathic concern, perspective taking and personal distress) with generalized linear modeling. Significant covariates on univariate linear regression analysis were included in the multivariate linear regression model. RESULTS: A total of 825 radiation oncologists completed all questionnaires. A higher level of alexithymia was associated to decreased CS (ß: -0.101; SE: 0.018; p < 0.001), increased STS (ß: 0.228; SE: 0.018; p < 0.001) and burnout (ß: 0.177; SE: 0.016; p < 0.001). A higher empathic concern was significantly associated to increased CS (ß: 0.1.287; SE: 0.305; p = 0.001), STS (ß: 0.114; SE: 0.296; p < 0.001), with no effect on burnout. Personal distress was associated to decreased CS (ß: -1.423; SE: 0.275; p < 0.001), increased STS (ß: 1.871; SE: 0.283; p < 0.001) and burnout (ß: 1.504; SE: 0.245; p < 0.001). CONCLUSIONS: Alexithymic personality trait increased burnout risk, with less professional satisfaction. Empathic concern was associated to increased stress, without leading to burnout, resulting in higher professional fulfillment. These results may be used to benchmark preventing strategies, such as work-hour restrictions, peer support, debriefing sessions, and leadership initiatives for professionals at risk.

Professional quality of life and burnout among medical physicists working in radiation oncology: The role of alexithymia and empathy.

BACKGROUND AND PURPOSE: The professional quality of life of radiation oncology professionals can be influenced by different contributing factors, including personality traits. Alexithymia involves deficits in emotion processing and awareness. Empathy is the ability to understand another's 'state of mind/emotion'. We investigated professional quality of life, including burnout, in radiation oncology, exploring the role of alexithymia and empathy and targeting the population of medical physicists (MPs), since this professional category is usually underrepresented in surveys exploring professional well-being in radiation oncology and MPs may experience professional distress given the increasing complexity of multimodal cancer care. MATERIAL AND METHODS: An online survey was addressed to ESTRO members. Participants filled out three questionnaires to evaluate alexithymia, empathy and professional quality of life: a) Toronto Alexithymia Scale (TAS-20); b) Interpersonal Reactivity Index (IRI); c) Professional Quality of Life Scale (ProQoL). Professional quality of life as per ProQoL was considered as dependent variable. The three domains of the ProQoL, namely compassion satisfaction (CS), secondary traumatic stress (STS) and burnout were correlated with alexithymia (as per TAS-20) and empathy (as per IRI with three subcategories: empathic concern, perspective taking and personal distress) and demographic/professional characteristics as independent variables. Generalized linear modeling was used. Significant covariates on univariate linear regression analysis were included in the multivariate linear regression model. RESULTS: A total of 308 medical physicists completed all questionnaires. Alexithymia as per TAS-20 was correlated to decreased CS (ß = -0.25, p < 0 0.001), increased likelihood for STS (ß = 0.26, p < 0 0.001) and burnout (ß = 0.47, p < 0 0.001). With respect to empathy, the 'Empatic Concern' subscale of the IRI was found to be a significant predictor for increased CS (ß = 0.19, p = 0 0.001) and increased STS (ß = 0.19, p < 0 0.001), without significant correlation with burnout. The individual's perception of being valued by own's supervisor was correlated to increased CS (ß = 0.23, p < 0.001), and decreased burnout (ß = -0.29, p < 0.001). CONCLUSIONS: Alexithymic personality trait increased the likelihood to develop burnout, with less professional satisfaction amongst MPs working in radiation oncology. Empathy results in higher professional fulfilment. These results may be used to benchmark preventing strategies, including peer support, debriefing sessions, leadership initiatives and work-load limitation strategies.

Radiomics and Machine Learning for Radiotherapy in Head and Neck Cancers.

Introduction: An increasing number of parameters can be considered when making decisions in oncology. Tumor characteristics can also be extracted from imaging through the use of radiomics and add to this wealth of clinical data. Machine learning can encompass these parameters and thus enhance clinical decision as well as radiotherapy workflow. Methods: We performed a description of machine learning applications at each step of treatment by radiotherapy in head and neck cancers. We then performed a systematic review on radiomics and machine learning outcome prediction models in head and neck cancers. Results: Machine Learning has several promising applications in treatment planning with automatic organ at risk delineation improvements and adaptative radiotherapy workflow automation. It may also provide new approaches for Normal Tissue Complication Probability models. Radiomics may provide additional data on tumors for improved machine learning powered predictive models, not only on survival, but also on risk of distant metastasis, in field recurrence, HPV status and extra nodal spread. However, most studies provide preliminary data requiring further validation. Conclusion: Promising perspectives arise from machine learning applications and radiomics based models, yet further data are necessary for their implementation in daily care.

Updates on the diagnosis and treatment of prostate cancer.

Prostate cancer is the second most prevalent cancer in males worldwide and the commonest cancer in males in the UK. The recent updates on the diagnosis and treatment of prostate cancer were discussed at a multidisciplinary day event organized by the British Institute of Radiology and held in London in November 2016. This day covered the use of the prostate-specific antigen biomarker and of advanced imaging techniques such as multiparametric and whole-body MRI, choline positron emission tomography/CT and gallium-labelled prostate-specific membrane antigen for the detection of prostate cancer. In addition, the results of several trials assessing the management of the disease were discussed, in particular the Prostate Cancer Intervention Versus Observation Trial and Prostate Testing for Cancer and Treatment trials which evaluated the gain of intervention vs observation, and four randomized controlled trials comparing hypofractionated and standard radiotherapy regimen. Further to this event, this commentary highlights the topical issues relating to recently published guidelines and to trials for the management of prostate cancer where these were discussed.

An external dosimetry audit programme to credential static and rotational IMRT delivery for clinical trials quality assurance.

PURPOSE: External dosimetry audits give confidence in the safe and accurate delivery of radiotherapy. The RTTQA group have performed an on-site audit programme for trial recruiting centres, who have recently implemented static or rotational IMRT, and those with major changes to planning or delivery systems. METHODS: Measurements of reference beam output were performed by the host centre, and by the auditor using independent equipment. Verification of clinical plans was performed using the ArcCheck helical diode array. RESULTS: A total of 54 measurement sessions were performed between May 2014 and June 2016 at 28 UK institutions, reflecting the different combinations of planning and delivery systems used at each institution. Average ratio of measured output between auditor and host was 1.002±0.006. Average point dose agreement for clinical plans was -0.3±1.8%. Average (and 95% lower confidence intervals) of gamma pass rates at 2%/2mm, 3%/2mm and 3%/3mm respectively were: 92% (80%), 96% (90%) and 98% (94%). Moderately significant differences were seen between fixed gantry angle and rotational IMRT, and between combination of planning systems and linac manufacturer, but not between anatomical treatment site or beam energy. CONCLUSION: An external audit programme has been implemented for universal and efficient credentialing of IMRT treatments in clinical trials. Good agreement was found between measured and expected doses, with few outliers, leading to a simple table of optimal and mandatory tolerances for approval of dosimetry audit results. Feedback was given to some centres leading to improved clinical practice.
