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.

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.

: 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.

Aim: To examine the prevalence of several cancer risk factors among TGD individuals compared with cisgender individuals.
As the rate of people openly identifying as transgender or gender diverse (TGD) is increasing, UK cancer genetics services are seeing growing numbers of TGD patients. Lack of appropriate clinical guidelines and a scarcity of robust data about the impact of gender-affirming treatments on cancer risk has led to uncertainty of how best to support TGD patients, and inequity in standards of care. To address this gap, the UK Cancer Genetics Group and Central & South Genomic Medicine Service Alliance facilitated a 2-day meeting to develop national consensus to support the management of TGD patients with inherited cancer risks.

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.

The ecological and evolutionary dynamics responsible for treatment failure are incompletely understood. Here, we performed a comprehensive multi-omic analysis of samples collected from EAC patients in the MEMORI clinical trial, revealing major changes in gene expression profiles and immune microenvironment composition that did not appear to be driven by changes in clonal composition.

Design/setting: Nationally representative, population-based cross-sectional survey in England with survey data collection from January to March 2021.
Participants: 840 691 survey respondents including 6333 trans and non-binary adults.
Importance: Limited prior research suggests that transgender and gender diverse (TGD) people may have higher mortality rates than cisgender people.
Objective: To estimate overall and cause-specific mortality among TGD persons compared with cisgender persons.
Design, Setting, And Participants: This population-based cohort study used data from general practices in England contributing to the UK's Clinical Practice Research Datalink GOLD and Aurum databases.
Genetic and epigenetic variation, together with transcriptional plasticity, contribute to intratumour heterogeneity. The interplay of these biological processes and their respective contributions to tumour evolution remain unknown. Here we show that intratumour genetic ancestry only infrequently affects gene expression traits and subclonal evolution in colorectal cancer (CRC).

However, DNA mutations alone do not fully explain malignant transformation. Here we investigate the co-evolution of the genome and epigenome of colorectal tumours at single-clone resolution using spatial multi-omic profiling of individual glands.

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.

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 review highlights recent developments with epigenetic editing technology in comparison with the canonical CRISPR-Cas genome editing, as well as the epistemic and ethical considerations with preemptive translation of epigenetic editing into clinical or commercial use in humans. Key considerations in safety, equity, and access to epigenetic editing are highlighted, with a spotlight on the ethical, legal, and social issues of this technology in the context of global health equity.

Here, we show that fluctuating DNA methylation marks can be used as clocks in cells where ongoing methylation and demethylation cause repeated 'flip-flops' between methylated and unmethylated states. We identify endogenous fluctuating CpG (fCpG) sites using standard methylation arrays and develop a mathematical model to quantitatively measure human adult stem cell dynamics from these data.

Aim: To understand the attitudes towards and preferences for cervical screening among UK-based TMNB.
Design And Setting: Cross-sectional survey of TMNB at an NHS gender identity clinic (GIC) and an NHS sexual health service specialising in care of transgender people.
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.
View Article and Find Full Text PDFCervical cancer mortality in the United Kingdom (UK) has decreased over the last decade, largely due to uptake of cervical cancer screening. However, only those with a female gender marker on their health records are invited, creating a significant barrier to gender minorities accessing screening. We undertook a systematic review to synthesise published literature on cervical cancer screening among eligible gender minorities, aiming to identify barriers and facilitators that might inform changes in UK policy and clinical practice.
