Advances in molecular biology, genetics, and epigenetics have refined our understanding of metastatic brain cancer and underscored the need for better classification and targeted approaches. The heterogeneity of brain metastases highlights the differences from their primary source of origin and contributes to therapeutic resistance. Before colonising the brain, tumour cells acquire specialised proficiencies that enable them to capitalise on the unique microenvironment of the brain. ⋯ These adaptations facilitate tumour survival, growth, and treatment resistance. Recognising metastatic brain cancer as a distinctive CNS disease, rather than an extension of the primary cancer, would support the development of rational approaches that target its molecular and genetic features and improve research funding in this area. Here, we delve into the distinct genetic and phenotypic characteristics of metastatic brain cancer, and reflect on how a change in the perception of this disease could accelerate the development of more effective therapies and drive continued progress in the field of neuro-oncology.

Randomized Controlled Trial Multicenter StudyTiragolumab in combination with atezolizumab and bevacizumab in patients with unresectable, locally advanced or metastatic hepatocellular carcinoma (MORPHEUS-Liver): a randomised, open-label, phase 1b-2, study.
PD-L1 and VEGF blockade with atezolizumab plus bevacizumab has been shown to improve survival in unresectable hepatocellular carcinoma. TIGIT is an immune checkpoint regulator implicated in many cancers, including unresectable hepatocellular carcinoma. Here, we evaluate the clinical activity and safety of the addition of tiragolumab, an anti-TIGIT monoclonal antibody, to atezolizumab plus bevacizumab. ⋯ F Hoffmann-La Roche and Genentech.

Global linear accelerator requirements and personalised country recommendations: a cross-sectional, population-based study.
The Linear Accelerator Shortage Index (LSI) is a practical tool for prioritising the deployment of linear accelerators (LINACs) in various regions within a country. The LSI reflects the ratio of LINAC demand to current availability. The aim of this study was to use the LSI to predict global LINAC needs and classify countries according to the degree of radiotherapy shortage (LINAC shortage grade). ⋯ None.

Multicenter StudyPsychosocial impact associated with a multicancer early detection test (PATHFINDER): a prospective, multicentre, cohort study.
PATHFINDER was a prospective cohort study of multicancer early detection (MCED) testing in an outpatient ambulatory population. The aim of this study is to report the patient-reported outcomes (PROs) collected as secondary and exploratory measures in the PATHFINDER study. ⋯ GRAIL.

ReviewManagement of immune checkpoint inhibitor-associated toxicities in older adults with cancer: recommendations from the International Society of Geriatric Oncology (SIOG).
Immune checkpoint inhibitors (ICIs) have substantially advanced the treatment landscape for a wide variety of malignancies. Older adults represent a large and rapidly growing demographic, among whom ICIs are widely prescribed. Management of ICI-associated toxicity among older adults, particularly in the presence of frailty and comorbidity, poses unique challenges. In this Policy Review, developed by the International Society of Geriatric Oncology (SIOG), we offer an evidence-based framework for health-care providers, caregivers, and policy makers for treating older adults with ICIs, focusing on unique considerations for this population that are not adequately addressed by existing guidelines, and expanding them to encompass geriatric oncology principles.
