Background: The role of combined modality in the adjuvant treatment of Endometrial Cancer has not been established. This study aims to assess the benefits of Sequential Chemoradiotherapy (SCRT) compared to Radiotherapy (RT) alone in the treatment of patients with Endometrial Cancer.
Methods: Retrospective analysis of patients with Endometrial Cancer stage I to stage III C at King Abdullah Medical city, Makkah. Each group of patients was assigned to receive External pelvic RT, brachytherapy or both. While a second group received SCRT consisting of six cycles of Carboplatin (AUC 5) and Paclitaxel 175 mg/m2 followed by radiotherapy.
Results: Fifty-six women were treated of which 26 received SCRT and 30 received RT. The two groups had a median age of 58 years old ranging from 34 - 84 years old with no other statistically significant difference. Patients who received SCRT had poorer prognostic tumor characteris-tics. Median follow-up was 29.6 months (95% CI: 19.6-39.5 months). All deaths (n=5) were exclusively in the RT group. The 2 and 4-year OS rates were 100% and 100% in SCRT group versus 87.3% and 64.9% in RT group (hazard ratio [HR] 0.018 [95% CI: 0-24.4; p= 0.038); The 2- and 4-year DFS were 100% and 100% in SCRT group versus 78.1% and 43.9% in RT group (HR 0.102 [95% CI: 0.103-0.805; p= 0.008).
Conclusion: Adjuvant chemotherapy given before radiotherapy for Endometrial Cancer may lessen the effect of high-risk features on the DFS and OS. Randomized clinical trials are needed to determine the benefits of early Systemic Therapy.

Objective: In England, through the Genomic Medicine Service Alliances (GMSAs), a national transformation project aims to embed robust pathways to deliver universal Lynch syndrome (LS) testing for patients with colorectal and endometrial cancers. Prior to commencement of the project, there was evidence of variation and low testing levels in eligible patients which is consistent with other health systems; however, we believe this is amenable to systematic improvement with responsibility for testing delivery by local cancer teams supported by regional infrastructure.
Methods And Analysis: A project team and national oversight group was formed in May 2021 with membership including 21×cancer alliances, 7×GMSAs, charities and other stakeholders who agreed key performance indicators.
Objective: To explore the impact of molecular subtype in endometrial cancer (EC) on CD8+T cell densities. Furthermore, this work will test the assumption that all mismatch repair deficient (MMRd) tumours are immunologically similar which would enable current trial data to be generalised to all MMRd ECs.
Methods And Analysis: All tumours were characterised into the four clinical molecular subtypes.

Transgender and gender-diverse (TGD) individuals face an elevated risk of cancer in comparison with the general population. This increased risk is primarily attributed to an imbalanced exposure to modifiable risk factors and a limited adherence to cancer screening programmes, stemming from historical social and economic marginalisation. Consequently, these factors contribute to poorer clinical outcomes in terms of cancer diagnosis and mortality.

Understanding how epithelial cells in the female reproductive tract (FRT) differentiate is crucial for reproductive health, yet the underlying mechanisms remain poorly defined. At birth, FRT epithelium is highly malleable, allowing differentiation into various epithelial types, but the regulatory pathways guiding these early cell fate decisions are unclear. Here, we use neonatal mouse endometrial organoids and assembloid coculture models to investigate how innate cellular plasticity and external mesenchymal signals influence epithelial differentiation.
