RESUMEN
There is evidence that gender-affirming hormone treatment (GAHT) for transgender individuals modulates their risk for specific malignancies including breast and prostate cancer, and meningiomas. However, there is insufficient data to make precise risk estimates accounting for age and inherited cancer risk. As such, screening recommendations remain broad. Even less evidence exists for best practice in the management of active or historical cancers in the transgender population. Guidance is therefore mainly extrapolated from cisgender populations but with considerations of the significant benefits of GAHT in the face of any hormonal risk. Clinical experience, the multidisciplinary team and shared decision making with the patient are vital in providing person-centred care, while further research is acquired.
RESUMEN
INTRODUCTION: Persistent infection with high-risk human papillomavirus (HPV) is the causal agent of several cancers including cervical, anal and oropharyngeal cancer. Transgender men and transmasculine non-binary (TMNB) people with a cervix are much less likely to undergo cervical cancer screening than cisgender women. Transgender women and transfeminine non-binary (TWNB) people assigned male at birth may be at increased risk of HPV. Both TMNB and TWNB people face many barriers to HPV testing including medical mistrust due to stigma and discrimination. METHODS AND ANALYSIS: The Self-TI Study (Self-TI) is a pilot study designed to measure acceptability and feasibility of HPV self-testing among transgender and non-binary people in England. TMNB people aged 25-65 years, with at least 1 year of testosterone, and TWNB people, aged 18 years and over, are eligible to participate. Participants self-collect up to four samples: an oral rinse, a first void urine sample, a vaginal swab (if applicable) and an anal swab. TMNB participants are asked to have an additional clinician-collected cervical swab taken following their routine Cervical Screening Programme sample. TWNB people are asked to take a self-collection kit to perform additional self-collection at home and mail the samples back to the clinic. Acceptability is assessed by a self-administered online survey and feasibility is measured as the proportion of samples returned in the clinic and from home. ETHICS AND DISSEMINATION: Self-TI received ethical approval from the Research Ethics Committee of Wales 4 and ethical review panel within the Division of Cancer Epidemiology and Genetics at the US National Cancer Institute. Self-TI was coproduced by members of the transgender and non-binary community, who served as authors, collaborators and members of the patient and public involvement (PPI) group. Results of this study will be shared with the community prior to being published in peer-reviewed journals and the PPI group will help to design the results dissemination strategy. The evidence generated from this pilot study could be used to inform a larger, international study of HPV self-testing in the transgender and non-binary community. TRIAL REGISTRATION NUMBER: NCT05883111.

Background: Sex and gender are vitally important in the study of epigenetic mechanisms for various types of cancer. However, little has been done to assess the state of sex and gender-based analyses (SGBA) in this field. The aim was to undertake a critical evaluation of sex and gender representation, discussion, and data analysis within the cancer epigenetics field since 2010. Methods: A PRISMA-ScR scoping review was conducted with 111 peer-reviewed studies comprising of colorectal, gastric, head and neck, hepatocellular carcinoma, and lung cancers. Data extraction and a quality appraisal were performed by a team of epidemiologists and bioethicists. Results: Of the 111 included studies, only 17 studies (15.3%) explicitly stated sex and gender analysis to be their primary aim. A total of 103 studies (92.8%) provided a detailed analysis of sex/gender as a biological or social variable, while the remaining 8 studies (7.2%) only stratified results by sex/gender. Although sex and gender were a key facet in all the eligible studies, only 7 studies (6.3%) provided an explicit definition of the terms "sex" or "gender", while the remaining 104 studies (93.7%) used the words "sex" or "gender" without providing a definition. A total of 84 studies (75.7%) conflated the concepts of "sex" and "gender", while 44 studies (39.6%) were inconsistent with their usage of the "sex" and "gender" terms. Conclusions: Very few studies offered a robust analysis of sex/gender data according to SAGER guidelines. We call for clear and directed guidelines regarding the use of sex/gender as a variable in epigenetics research.
RESUMEN
Sex differences in cancer risk and outcome are currently a topic of major interest in clinical oncology. It is however unknown to what extent cancer researchers consider sex as a biological variable for their research. We conducted an international survey among 1243 academic cancer researchers and collected both quantitative and qualitative data. Although most of the participants indicated that they were familiar with the concept of studying sex differences in cancer biology, they did not think it was important to investigate sex differences in every context of cancer research nor in all tumor types. This is in stark contrast to the current recommendations and guidelines and illustrates the need for increased awareness among cancer researchers regarding the potential impact of the sex of cell lines, animals, and human samples in their studies.
RESUMEN
Over the past decade, bioethicists, legal scholars and social scientists have started to investigate the potential implications of epigenetic research and technologies on medicine and society. There is growing literature discussing the most promising opportunities, as well as arising ethical, legal and social issues (ELSI). This paper explores the views of epigenetic researchers about some of these discussions. From January to March 2020, we conducted an online survey of 189 epigenetic researchers working in 31 countries. We questioned them about the scope of their field, opportunities in different areas of specialization, and ELSI in the conduct of research and knowledge translation. We also assessed their level of concern regarding four emerging non-medical applications of epigenetic testing-i.e., in life insurance, forensics, immigration and direct-to-consumer testing. Although there was strong agreement on DNA methylation, histone modifications, 3D structure of chromatin and nucleosomes being integral elements of the field, there was considerable disagreement on transcription factors, RNA interference, RNA splicing and prions. The most prevalent ELSI experienced or witnessed by respondents were in obtaining timely access to epigenetic data in existing databases, and in the communication of epigenetic findings by the media. They expressed high levels of concern regarding non-medical applications of epigenetics, echoing cautionary appraisals in the social sciences and humanities literature.

Background: Lesbian, gay, bisexual, transgender, queer or questioning (LGBTQ+) people experience healthcare inequalities in cancer care. Previous studies have focused on knowledge, attitudes and behaviours of healthcare professionals (HCPs) treating adults with cancer and how these contribute to inequalities. To date, no research has focused on HCPs treating LGBTQ+ children and adolescents with cancer in the UK. This is important given that this group may be at a critical time for exploring their gender identity and sexual orientation, whilst also facing a cancer diagnosis. We aimed to explore the knowledge, attitudes and behaviours of paediatric, teenage and young adult oncology HCPs treating LGBTQ+ patients in the UK. Methods: We carried out semi-structured interviews with 8 HCPs in paediatric, teenage and young adult (TYA) oncology from the Royal Marsden NHS Foundation Trust. Eight questions were asked, which centred around participants' knowledge, attitudes and behaviours regarding management of LGBTQ+ patients in oncology. Interview transcripts were analysed by inductive thematic analysis. Results: We identified 10 themes, including novel themes (how HCPs acquire knowledge and expectations of a 'third party' to be the expert) which may underlie previously observed trends in knowledge, attitudes and behaviours of HCPs. We highlight other themes and HCP concerns specific to care of LGBTQ+ patients in paediatrics (influence of the parental-carer dynamic, concerns around patient age and development as a barrier to disclosure) which require further research. We found evidence of the interrelatedness of HCP knowledge, attitudes and behaviours and the ability of these elements to positively influence each other. We mapped our themes across these elements to form a new suggested framework for improving HCP-patient interactions in LGBTQ+ Cancer Care. We found a need both for individual HCP education and organisational change, with creation of a culture of psychological safety to improve patient care. Conclusion: Knowledge, attitudes and behaviours of HCPs are closely interdependent when providing care to young LGBTQ+ patients with cancer. The authors suggest that future efforts to improve care of these patients address this complexity by spanning the domains of our suggested framework. Whilst HCP education is essential, change must also occur at an organisational level.
RESUMEN
Sex hormones are crucial for the body's development and function. Therefore, many transgender people seek hormone therapy as part of their transition. However, sex hormones modulate cancer risk. Studying sex hormones in cisgender and transgender populations will improve our knowledge of their biological role in cancer and reduce health disparities.

INTRODUCTION: Over one million people in the UK identify as LGBTQ+ (lesbian, gay, bisexual, transgender, queer or questioning). Research has shown that this population experience differing cancer risk factors compared with non-LGBTQ+ patients and persistent inequalities in cancer care. Literature concerning the knowledge of oncologists of this group's healthcare needs is limited; our study aimed to evaluate knowledge, attitudes and behaviours of UK oncologists about LGBTQ+ patients. METHODS: A 53-question survey was delivered via a secure online platform. Questions covered respondent demographics, knowledge, attitudes and behaviours with the majority of responses on a Likert scale. Oncologists were recruited via email from professional bodies and social media promotion. Informed consent was sought and responses fully anonymised. Multifactorial ordinal logistic regression and Fisher's exact test were used to assess for interactions between demographics and responses with Holm-Bonferroni multiple testing correction. RESULTS: 258 fully completed responses were received. Respondents had a median age of 43 years (range 28-69); 65% consultants and 35% registrars; 42% medical, and 54% clinical, oncologists. 84% felt comfortable treating LGBTQ+ patients but only 8% agreed that they were confident in their knowledge of specific LGBTQ+ patient healthcare needs. There were low rates of routine enquiry about sexual orientation (5%), gender identity (3%) and preferred pronouns (2%). 68% of oncologists felt LGBTQ+ healthcare needs should be a mandatory component of postgraduate training. CONCLUSIONS: This survey showed that UK oncologists feel comfortable treating LGBTQ+ patients but may fail to identify these patients in their clinic, making it more difficult to meet LGBTQ+ healthcare needs. There is self-awareness of deficits in knowledge of LGBTQ+ healthcare and a willingness to address this through postgraduate training. Educational resources collated and developed in accordance with this study would potentially improve the confidence of oncologists in treating LGBTQ+ patients and the cancer care these patients receive.

Neuroendocrine neoplasms (NENs) arise from cells of neuronal and endocrine differentiation. While they are a rare entity, an increasing proportion of patients with NEN present with metastatic disease and no evident primary site using routine imaging or histopathology. NENs of unknown primary site have a poorer prognosis, often due to the challenge of selecting appropriate evidence-based management. We review the available literature and guidelines for the management of NENs of unknown primary site including clinical features, biochemical tests, histopathology, imaging, surgical exploration and localised and systemic treatments. We also discuss novel molecular techniques currently under investigation to aid primary site identification.

Neurological conditions present a challenge when obtaining consent for lumbar punctures (LPs), as patients often have -visual, hearing or cognitive impairments. The aim of this -project was to improve the quality of the consent process for LPs. Surveys of doctors and patients suggested there was scope to standardise and improve information provided during the consent process. A patient information video was -developed using online software and shown to patients using tablet -computers. Patient surveys were distributed to re-assess the quality of the process for obtaining consent. There was a -significant improvement (p=0.031) in the median response score after the video was presented to the same group of patients. The use of patient information videos -significantly improves understanding and recall of the procedure, and -satisfaction with the consent process. In conclusion, audio--visual tools are a valuable tool for standardising and -improving the process of gaining consent for LPs.
RESUMEN
A 74-year-old woman presenting with acute abdominal pain underwent surgery for suspected small bowel ischaemia. At laparotomy, a sacrocolpopexy mesh in the pelvis, which had been inserted 8 years previously, was found to be causing strangulation of a 2-m length of the small bowel. Following resection and primary anastomosis, the patient spent several days in intensive care before her eventual discharge. This unusual life-threatening complication should be considered in patients presenting with abdominal pain even many years following abdominal sacrocolpopexy.
