Copper is an essential trace element with inherent redox properties and fundamental roles in a diverse range of biological processes; therefore, maintaining copper homeostasis is crucial. In this Review, the authors discuss new insights into the mechanisms by which disrupted copper homeostasis contributes to tumour initiation and development, including the recently defined concepts of cuproplasia (copper-dependent cell growth and proliferation) and cuproptosis (a mitochondrial pathway of cell death triggered by excessive copper exposure). They also discuss potential strategies to exploit cuproplasia and cuproptosis for the treatment of cancer.
The benefits and potential harms of mammography-based screening for breast cancer are often a matter of debate. Here, I discuss the promises and limitations of a recent study that tested an artificial intelligence-based tool for the detection of breast cancer in digital mammograms in a large, prospective screening setting.
FGFR inhibitors are now approved for use in patients with advanced-stage urothelial carcinoma, cholangiocarcinoma and myeloid or lymphoid neoplasms that harbour certain FGFR alterations. Nonetheless, challenges such as tolerability and acquired resistance limit the clinical potential of these agents. In this Review, the authors summarize the available clinical data on FGFR inhibitors, describe promising novel agents and highlight future research directions that might optimize the efficacy of FGFR-targeted therapies.
Patients with early stage hepatocellular carcinoma typically undergo resection, liver transplantation or local ablation; however, 30–50% will have disease recurrence at 3 years. The authors of this Review describe the tumour immune microenvironment and mechanism of action of immunotherapies, and discuss the available evidence from phase II/III trials of neoadjuvant and adjuvant treatment approaches in this setting.
Increasing evidence indicates that signalling networks activated downstream of oncogenic alterations contribute fundamentally to cancer immune evasion, including by promoting the accumulation of regulatory T (Treg) cells and other immunosuppressive cells in the tumour microenvironment (TME). Herein, the authors discuss the mechanisms via which cancers engage Treg cells to evade antitumour immunity, as well as the characteristics of Treg cells in the TME and their roles in resistance to immune-checkpoint inhibitors. Considering these aspects, they propose the concept of ‘immuno-genomic cancer evolution’ for tumorigenesis and the related paradigm of ‘immuno-genomic precision medicine’, postulating that the specific characteristics of cancer, especially genetic profiles that correlate with particular immunosuppressive networks in the TME, are likely to inform individualized strategies for combining molecularly targeted agents with immunotherapies.
In 2023, the US FDA approved several new cancer drugs and biologic agents, including seven small-molecule inhibitors, four bispecific T cell engagers, two anti-PD-1 antibodies and one cell therapy product. Regulatory focus areas included analyses of biomarker-positive subgroups that drive efficacy, equipoise in randomized controlled trials and a new authority to require confirmatory trials be underway before accelerated approval.
Ataxia telangiectasia and Rad3-related protein serine/threonine kinase (ATR) is a mediator of the cellular replication stress response that, upon activation, initiates a cascade of coordinated reactions that ultimately enables DNA repair. This biological function makes ATR an attractive therapeutic target in cancers with elevated replication stress or DNA-repair deficiency. This Review discusses the currently available results from clinical trials testing ATR inhibitors as well as challenges and solutions in the development of this therapeutic class.
Dendritic cells (DCs) are antigen-presenting cells that function at the interface between innate and adaptive immunity, thereby acting as key mediators of antitumour immune responses and immunotherapy efficacy. In this Review, the authors outline the emerging complexity of intratumoural DC states that is being revealed through single-cell analyses as well as the contributions of different DC subsets to anticancer immunity and the activity of immune-checkpoint inhibitors. The authors also discuss advances in the development of DC-based cancer therapies and considerations for their potential combination with other anticancer therapies.
The US FDA Accelerated Approval of sotorasib required the sponsor to conduct a randomized trial that compared the safety and efficacy of the approved dose with a lower dose. These results, recently disclosed, have important implications for patients, payers, oncologists and the pharmaceutical industry.
Durable responses with first-line platinum-based chemotherapy for advanced-stage urothelial carcinoma are rare, and patient outcomes are poor. Recently, CheckMate 901 became the first phase III trial to establish a significant overall survival benefit from a combined chemoimmunotherapy approach in this disease setting. Herein, we discuss key findings from CheckMate 901 and their implications in the context of a rapidly evolving treatment landscape.
