Accepted: 2026) UK consensus recommendations for onward testing for Lynch Syndrome in patients

Addition of chemotherapy to radiotherapy promotes progenitor-exhausted CD8⁺ T-cell clonal dominance in head and neck cancer

Abstract Concomitant chemoradiotherapy (CRT) is a standard-of-care treatment for unresectable locally advanced head and neck squamous cell carcinoma (LA-SCCHN), but its immune effects, particularly relative to radiotherapy (RT) alone, remain incompletely understood. Using syngene...

Postoperative outcomes and costs associated with multimodal prehabilitation for advanced ovarian cancer surgery: an exploratory retrospective cohort study at a UK specialist centre

Neoadjuvant chemotherapy (NACT) followed by cytoreductive surgery (CRS) is the standard of care for advanced ovarian cancer and is associated with deconditioning and a high burden of perioperative morbidity. Multimodal prehabilitation may attenuate physiological decline during NA...

Werner helicase inhibitor for advanced microsatellite instability solid tumors: a phase 1 trial

Abstract Werner syndrome helicase (WRN) is a synthetic lethal target for microsatellite instability (MSI) cancers. In part 1 of this ongoing first-in-human, phase 1 trial, escalating doses of RO7589831 (VVD-133214), a first-in-class, WRN covalent inhibitor, were evaluated in 88 p...

Management of Soft Tissue and Visceral Leiomyosarcomas

Importance Leiomyosarcoma is a rare and heterogeneous malignant mesenchymal neoplasm associated with substantial morbidity and mortality. Given recent advances in biologic understanding and the complexity of leiomyosarcoma, a consensus-driven approach is needed to harmonize manag...

Extended Follow-Up of Botensilimab Plus Balstilimab in an Expanded Cohort of Microsatellite-Stable Metastatic Colorectal Cancer Without Active Liver Metastases

PURPOSE: Microsatellite-stable metastatic colorectal cancer (MSS mCRC) has limited treatment options and responds poorly to conventional immunotherapy. We report extended follow-up results from a fully-enrolled, phase 1b cohort evaluating botensilimab (BOT; Fc-enhanced anti-CTLA-...

Targeting Overweight and Obesity Phenotypes for Secondary Prevention of Cardiovascular Disease: A Call to Action for the Middle East and Beyond

ABSTRACT Although there are conflicting clinical data on the efficacy of weight reduction in reducing secondary events in patients with comorbid overweight and obesity (OAO) and cardiovascular disease (CVD), there is excellent epidemiological and biological evidence of a cause–ef...

In-depth characterisation of the tumour microenvironment reveals HHV-8-dependent immune regulation in HIV-associated and classic Kaposi sarcoma

BACKGROUND: Kaposi's sarcoma (KS) is the most common malignancy occurring in people living with HIV (PLWH). The clinical course of KS in PLWH established on combined anti-retroviral therapy (cART) resembles that of classic KS. OBJECTIVES: To compare the clinical and biological ch...

The mirrored burden and accountable handovers in cancer survivorship: co‑designing a post‑treatment transition standard

Post-treatment transitions after active cancer care often lack clear ownership, timelines and closure rules, shifting coordination work onto survivors and staff. We aimed to identify how these failures arise and to co-design a handover standard for post-treatment survivorship car...

Sex-based survival differences in patients with untreated advanced oesophageal squamous cell carcinoma receiving chemotherapy and immune checkpoint inhibitors: a meta-analysis

Purpose Chemotherapy combined with immune checkpoint inhibitors (ICIs) is the standard first-line treatment for patients with advanced oesophageal squamous cell carcinoma (OSCC). Evidence from other tumour types suggests that biological sex may influence ICI efficacy, but this re...
